A package exploded early this morning at a FedEx facility in Schertz, Texas, about 60 miles south of Austin, according to the FBI and local law enforcement. According to media reports, it was bound for Austin.

"Early this morning, Schertz Police responded to the Fedex facility in the 9900 block of Doerr Lane for a report of an explosion," Schertz police wrote on Facebook. "Further investigation revealed the explosion came from a package in the sorting area of the facility. One person was treated and released at the scene."

In a statement, FedEx confirmed one employee sustained injuries in the blast.

"We can confirm that a single package exploded while in a FedEx Ground sortation facility early this morning. One team member is being treated for minor injuries," FedEx said. "We are working closely with law enforcement in their investigation. We are not providing any additional specific information about this package at this time."

The explosion comes amid a string of four bombings that have struck Austin over the past three weeks. Two people have been killed, and four others wounded.

“We believe that the [latest] explosion is likely connected to our overall investigation into the bombings,” FBI Special Agent Michelle Lee told KUT.

The Austin Fire Department says it has received calls about a suspicious package at a FedEx facility on 4117 McKinney Falls Parkway, near the Austin-Bergstrom International Airport. The fire department's hazardous materials team is at the scene with the Austin Police Department and Austin-Travis County Emergency Medical Services. </s> AUSTIN, Texas >> Emergency teams were responding Tuesday night to another reported explosion in Texas’ capital, this one at a Goodwill store in the southern part of the city.

In a tweet, the Austin Police Department urged residents to avoid the area. Austin-Travis County EMS said there had been reports of at least one person injured, though it was not immediately clear how serious the injuries were.

It came as investigators who have pursued a suspected serial bomber terrorizing Austin for weeks uncovered what seemed like valuable new leads in the case.

Even before the report of the Goodwill blast, it had already been a busy day for authorities. Before dawn Tuesday, a bomb inside a package exploded around 1 a.m. as it passed along a conveyer belt at a FedEx shipping center near San Antonio, causing minor injuries to a worker. The Austin Police Department, the FBI and other federal agencies confirmed that the package center blast was related to four previous ones that killed two people and seriously injured four others.

That explosion occurred at a FedEx facility in Schertz, just northeast of San Antonio and about 60 miles southwest of Austin.

Later in the morning, police sent a bomb squad to a FedEx facility outside the Austin airport to check on a suspicious package that was reported around 6:20 a.m. Federal agencies and police later said that package had indeed contained an explosive that was successfully intercepted by authorities. They added that the intercepted package, too, was believed to be related to the other bombings.

Meanwhile, authorities also closed off an Austin-area FedEx store where they believe the bomb that exploded was shipped to the distribution center. They roped off a large area around the shopping center in the enclave of Sunset Valley and were collecting evidence, including surveillance camera footage.

Then, authorities closed off an Austin-area FedEx store where they believe the bomb that exploded was shipped to the distribution center — roping off a large area around the shopping center in the enclave of Sunset Valley and were collecting evidence, including surveillance camera footage.

U.S. Rep. Michael McCaul, a Republican from Austin who is chairman of the House Homeland Security Committee, said that investigators have obtained surveillance videos that “could possibly” show a suspect, but are still poring through video.

“I hope his biggest mistake was going through FedEx,” McCaul, who has spoken to federal investigators and Austin police Chief Brian Manley, said of the bomber in a phone interview.

He added that the person responsible for the bombings had previously been “very sophisticated in going around surveillance cameras.”

“They’ve got a couple of videos that could possibly be the person but they’re not sure at this point,” McCaul said.

Before it exploded, the package had been sent from Austin and was addressed to a home in Austin, Texas Attorney General Ken Paxton said.

In a statement, FedEx officials said the same person responsible for sending the package also shipped a second parcel that has been secured and turned over to law enforcement. A company spokeswoman refused to say if that second package might have been linked to the one reported at the distribution center near the airport.

The Schertz blast came less than two days after a bombing wounded two men Sunday night in a quiet Austin neighborhood about 3 miles from the FedEx store. It was triggered by a nearly invisible tripwire, suggesting a “higher level of sophistication” than agents saw in three package bombs previously left on doorsteps, according to Fred Milanowski, the agent in charge of the Houston division of the Bureau of Alcohol, Tobacco, Firearms and Explosives.

A criminologist at the University of Alabama said if a single perpetrator is behind the blasts, changing the means of delivery increases the bomber’s chance of getting caught.

“I think it would suggest that the bomber is trying to stay unpredictable,” Adam Lankford said. “But it also increases the likelihood that he would make a mistake.”

Authorities have not identified the two men who were hurt Sunday, saying only that they are in their 20s and white. But William Grote told The Associated Press that his grandson was one of them and that he had what appeared to be nails embedded in his knees.

On the night of the fourth bombing, one of the victims was riding a bike in the street and the other was on a sidewalk when they hit the tripwire.

“It was so dark they couldn’t tell, and they tripped,” Grote said.

In Washington, President Donald Trump said the assailant behind the bombing is “very sick.”

During an Oval Office meeting Tuesday with Saudi Arabia’s Crown Prince Mohammed bin Salman, the president said, “This is obviously a very sick individual or individuals,” and authorities are “working to get to the bottom of it.”

Despite bombing tactics that have now shifted, investigators have repeated prior warnings about not touching unexpected packages and urged people to be wary of any stray object left in public. Austin police say they have now responded to more than 1,200 reports of suspicious packages in a little more than a week — without finding anything dangerous.

Officers originally pointed to possible hate crimes, but the victims have now been black, Hispanic and white and from different parts of the city.

“We are clearly dealing with what we believe to be a serial bomber,” Manley says.

Associated Press writers Jim Vertuno in Austin and Matt Sedensky in New York contributed to this report. </s> (CNN) Austin, Texas has been on edge after a string of package bomb explosions -- but a possible blast reported Tuesday night turned out to be unrelated, police say.

The latest incident turned out to be a Goodwill worker who was injured by simulated military ordnance in a donation box.

The worker's injuries were not life-threatening and he was treated and released from a hospital, officials said.

Earlier, authorities said they were responding to a report of a possible explosion, setting off fears a serial bomber had struck again in the Texas capital.

The Goodwill employee found two artillery simulators in a box of dropped-off items, and was injured when one of the ordnances "initiated," Assistant Chief of Austin Police Ely Reyes told reporters.

"This incident is not related to any of the other incidents that we've had here in Austin," Reyes said at a late-night news conference. He added that it didn't appear a copycat was responsible for the Goodwill box.

#UPDATE: There was no package explosion in the 9800 block of Brodie Ln. Items inside package was not a bomb, rather an incendiary device. At this time, we have no reason to believe this incident is related to previous package bombs. #Breaking #packagebombmurders — Austin Police Dept (@Austin_Police) March 21, 2018

The news of the incident came on a day two packages, one in a different part of Texas, caused authorities to widen their investigation.

The two packages, one that exploded at a FedEx sorting center near San Antonio and another later discovered back in Austin, are connected to four bombings in Austin, law enforcement agencies said Tuesday evening.

The ATF tweeted Tuesday evening that it, the FBI and Austin police had confirmed the connection.

One package Tuesday injured a FedEx worker in Schertz, near San Antonio, when the parcel went off just after midnight, officials said. Schertz is a little more than an hour southwest of Austin.

A second package, which was found at a FedEx facility near Austin's international airport, was being examined by authorities, the FBI's San Antonio office said in a tweet Tuesday afternoon.

Tuesday's developments added to the anxiety in the state capital, where four package bombs that caused two deaths and reports of other dubious parcels have Austin in what one US lawmaker from Texas described as "absolute panic."

Key developments

• A FedEx spokesman, Jim McCluskey, said of the person who sent the package that exploded Tuesday, "The individual responsible also shipped a second package that has now been secured and turned over to law enforcement."

• The company also gave law enforcement "extensive evidence related to these packages and the individual that shipped them collected from our advanced technology security systems," McCluskey added in a statement.

An ATF vehicle sits at a FedEx sorting center where a package exploded Tuesday in Schertz, Texas.

• The FBI is investigating a "confirmed link" between packages involved in the Austin investigations and a mail delivery office in Sunset Valley, southwest of downtown Austin, police in Sunset Valley said Tuesday. They did not indicate which packages were connected to the Sunset Valley office.

• The FedEx explosion represents a new method for the bomber or bombers. None of the four previous explosives was shipped, police have said.

• Schertz Police Chief Michael Hansen said he was confident the package that exploded there was not meant to target that facility or the city, though he wouldn't say why.

• FBI Special Agent James Smith declined to answer reporters' questions about whether the package that blew up was destined for Austin. Smith also said he had no reason to believe people in Schertz face any threat.

• There have been more than 1,200 calls about suspicious packages that have come in since March 12, Austin police said

• Rep. Sheila Jackson Lee asked an FBI acting deputy director for a briefing in Washington on efforts to find the bomb maker. "There is absolute panic in Austin," said Jackson-Lee, who represents Houston.

• President Donald Trump did not comment when asked Tuesday if he thought the bombings were acts of domestic terrorism. Trump called the situation "absolutely disgraceful" and said of those responsible: "We have to find them really immediately."

The four Austin bombings

In Austin, authorities have been combing for clues to the four explosions there, the first three of which involved cardboard packages left in front yards or on porches. They weren't delivered by the US Postal Service or services such as UPS or FedEx, police say.

Those three explosions -- one on March 2 and two more on March 12 -- killed or wounded three African-American people and one Hispanic person. The blasts happened in east Austin areas that predominantly have minority residents, and some in the area expressed concern the attacks might have been racially motivated

Police have not uncovered a motive and have not ruled out the possibility those bombings could be hate crimes.

In the fourth blast, a device Sunday was triggered by a tripwire, injuring two white men, police said. It had been left on the side of a road in a predominantly white area. Those men are in good condition at St. David's South Austin Medical Center, a hospital representative said.

"The use of a tripwire is far less discriminating than leaving parcel bombs at residences and suggests that (Sunday's) victims were not specifically targeted," the global think tank Stratfor said in one of its Threat Lens reports.

At the Schertz FedEx facility, a package that was moving along an automated conveyor exploded around 12:25 a.m. Tuesday, Hansen said. A worker standing near the explosion suffered minor injuries and was treated and released, officials said.

If one perpetrator is behind all five blasts, then the person deployed an unusually wide range of skills and delivery methods, CNN law enforcement analyst James Gagliano said.

"Some of these folks ... as long as the bomb maker walks away with 10 fingers and 10 toes, that's successful to them," said Gagliano, a retired FBI supervisory special agent.

"But the method, the delivery system and the different means that he's having these things in place shows that he's trying to show -- if it's the same person on all five of these -- a full panoply of different ways of doing this," he added, "and that's frightening."

Three members of the Congressional Black Caucus called Monday for federal officials to classify the bombings as terrorist attacks and determine whether they are "ideologically or racially motivated."

'I was pretty scared'

Brian Jaimes, 19, a package handler at the FedEx facility near Austin where investigators were working on a suspicious package, said employees were called to the front office and then told to leave the building.

"I was pretty scared," said Jaimes, who has worked at the facility for four months.

When asked whether the news about the bombings has made him nervous about coming to work, he said: "I try not to think about it, especially since I work (at a package shipper)."

What agencies are involved?

More than 350 special agents assigned by the FBI, as well as Bureau of Alcohol, Tobacco, Firearms and Explosives agents and forensic investigators in Quantico, Virginia, are on the Austin case.

At the state level, about 100 Texas Department of Public Safety officers, sergeants and special agents as well as the Texas Ranger bomb squad, bomb-sniffing dogs, intelligence agents and helicopters are also involved, CNN affiliate KXAN reported.

Police departments in Houston and San Antonio are sending bomb technicians and canine teams to Austin, their police chiefs said Monday.

How are they examining the evidence?

ATF has taken evidence from the four blast sites in Austin, Police Chief Brian Manley said.

"The prior three scenes are already in the lab at Quantico, and the evidence from the scene from last night is on its way to Quantico as well," he told CNN's Anderson Cooper on Monday night.

"They're looking at the devices, they're comparing them, looking for similarities," he said. "The similarities they've seen to this point, lead them to believe -- as we do -- that these are all being constructed by the same person or persons who are responsible for this."

How are officials handling the tips?

Austin police have received lots of tips, Manley said Monday night.

"As each tip comes in, it gets assigned to either a team of FBI agents, ATF agents or Austin police detectives to do follow-up work on," he said.

Manley urged residents to call police with any information.

"No matter how inconsequential you think it may be, that may be the piece of evidence we need to link it together and solve this before we have someone else in our community that gets seriously injured or killed," he said.

What are police asking residents to do?

Police are appealing to residents to pay attention to their surroundings. Residents shouldn't approach or touch anything that looks suspicious, Manley said.

A sixth suspected package bomb was discovered at an Austin FedEx depot Tuesday morning, hours after a package exploded at a San Antonio facility.

Cops in the Texas city probed a parcel in a depot close to Austin’s airport, and sealed off nearby roads.

Specialist fire services were sent to the scene, as 500 FBI agents were put on the case in a bid to halt the bombing campaign that has already killed two people.

Workers at the depot said they were evacuated, hours after a female FedEx worker was injured when a package filled with nails and metal shrapnel exploded in San Antonio shortly after midnight.

She escaped with ringing in her ears.

The latest incident comes a day after a tripwire device sprayed two cyclists with nails

That blast– the fourth this month – left two young men seriously injured and the city on edge.

Police said the explosion was connected to three previous bombings in Austin and the bomber used a tripwire in the latest attack, showing a higher level of skill.

It came a week after an exploding package killed Austin teenager Draylen Mason, 17.

The same afternoon, another package exploded and killed an elderly Hispanic woman in Austin, ten days after Anthony Stephan House was killed by an exploding package in the same Texan city.

Police are not believed to have identified any suspects for the attacks, and prompted widespread panic after warning Austin locals not to open any unexpected packages.

It was initially feared the bomber could have a racist motive, as the first three bombs killed two African American men, and injured an elderly Hispanic lady.

However, the two men injured in Sunday’s tripwire attack were white, which cast doubts over whether the attacker is a far-right extremist. </s> (CNN) -- A suspect in a wave of bombing attacks in Austin killed himself inside his car with an explosive device early Wednesday as authorities closed in, police said.

Since the bombings started on March 2, investigators frantically searched for clues, calling the attacks the work of a"serial bomber" who increasingly changed tactics. The bombings killed two people and left the Texas capital terrorized with fear for 19 days.
• In the past 36 hours, law enforcement received information directing them to a person of interest, who ultimately became a suspect.
• Surveillance teams tracked the suspect's vehicle to a hotel in Round Rock, north of Austin. As police waited on tactical units, the vehicle left the hotel.
• SWAT approached the vehicle and the suspect detonated a bomb, killing himself and injuring a SWAT member.
• A SWAT officer fired his weapon at the suspect after an officer was knocked down by the blast. It's unclear whether the officer shot the suspect.
• The suspect is a 24-year-old white man, and authorities don't know whether he acted alone or what his motive was.
• He is responsible for all the incidents in Austin, Austin Police Chief Brian Manley said.
• "This is the culmination of three very long weeks in our community," Manley said.
• He urged residents to be vigilant, saying they don't know where the bomber has been for the past 24 hours and if he sent additional packages.
• "Austin bombing suspect is dead. Great job by law enforcement and all concerned!," President Donald Trump tweeted.

In the latest incident,a package exploded at a FedEx sorting center near San Antonio on Tuesday, and a second unexploded bomb was discovered on the same day at another FedEx facility near Austin.

Those two packages are connected to four previous bombings that left two people dead. FedEx said the person who sent the package that exploded Tuesday also shipped a second one that was turned over to law enforcement officials.

FedEx said it provided authorities with "extensive evidence" from its security system on the packages and the person who shipped them.

In the incident near San Antonio, the device detonated on an automatic conveyor, Police Chief Michael Hansen said. A female employee was treated on site and released. The FedEx facility was not the intended target.

A possible explosion reported Tuesday night at a Goodwill store in Austin turned out to be unrelated. In that incident, an employee was injured by two "artillery simulators" in a donation box, said Ely Reyes, Austin's assistant police chief. The employee was treated and released from a hospital, Reyes said.

With every change in the bomber's tactic, Austin residents are getting increasingly nervous.

Grocery stores, apartment buildings and restaurants have been evacuated at a moment's notice as investigations intensify.

"This is terrorizing the city of Austin," Rep. Michael McCaul told President Donald Trump on Tuesday.

As investigators search for answers, they are checking the cameras at the facilities from Tuesday's incidents, the source said.

Investigators believe the same person is behind all the devices, the source said, adding that the devices have a lot of consistencies. They are similar in the way they are made and use the same items, including a "mouse trap" or a "close pin" switch, according to the source.

"We made one to show everyone what it looks like and we did it in an hour," the source said. The the bombmaker may have taken longer to do it to avoid blowing themselves up, according to the source.

The level of bombmaking skill doesn't necessarily point to military experience, the source added.

Investigators said the package that was found intact Tuesday may yield some clues.

"Now we have the blueprint and possible DNA on the inside of the bomb. So teams are working to render it safe and then look for DNA," the source said. The outside of the package would have been touched by employees at the store where it was dropped off and by the bombmaker, the source said.

The bombmaker may have been wearing gloves.

Of the four previous explosions in Austin, the first three involved cardboard packages left in front yards or on porches. They weren't delivered by the US Postal Service or services such as UPS or FedEx, police say.

Those three explosions -- one on March 2 and two more on March 12 -- killed or wounded three African-Americans and one Hispanic person. They happened in east Austin areas with predominantly minority residents. Some residents expressed concern the attacks might have been racially-motivated.

The first explosion killed 39-year-old Anthony Stephan House on March 2. The second blast on March 12 killed 17-year-old Draylen Mason. The third blast happened several hours later and critically injured a 75-year-old woman.

Those three blasts all happened after someone left explosives-laden packages on the victims' doorsteps.

In the fourth blast, a device was triggered by a tripwire, injuring two white men in a predominantly white area.

Police have not ruled out the possibility that those bombings could be hate crimes. They urged residents to pay attention to their surroundings, and not approach or touch anything that looks suspicious. </s> ROUND ROCK, Texas — The suspect in the Austin explosions has died, multiple CNN affiliates reported, citing law enforcement sources. CNN is working to confirm this latest information.

Since March 2, a serial bomber has terrorized the Texas capital, leaving several explosive packages around the city.

Highway closure: Police shut down parts of Interstate 35 early Wednesday following an officer-involved shooting. It’s unclear whether it was related to the explosions investigation.

Lots of officers: Police cars swarmed the area as sirens blared, with police, the FBI and other federal agencies at the scene.

Latest incident: A package exploded at a FedEx sorting center near San Antonio on Tuesday, and a second unexploded bomb was discovered on the same day at another FedEx facility near Austin. Those two packages are connected to four previous bombings that left two people dead.

Secured: FedEx said the person who sent the package that exploded Tuesday also shipped a second one that was turned over to law enforcement officials.

Evidence: The company said it provided authorities with “extensive evidence” from its security system on the packages and the person who shipped them.

Connected: Austin police and the FBI say the two packages at separate FedEx facilities are connected to the four previous package explosions in the Texas capital.

Wrong target: In the incident near San Antonio, the device detonated on an automatic conveyor, Police Chief Michael Hansen said. A female employee was treated on site and released. The FedEx facility was not the intended target.

Unrelated: A possible explosion reported Tuesday night at a Goodwill store in Austin turned out to be unrelated. In that incident, an employee was injured by two “artillery simulators” in a donation box, said Ely Reyes, Austin’s assistant police chief. The employee was treated and released from a hospital, Reyes said.

Numerous calls: Austin Police say they’ve responded to 1,257 reports of suspicious packages since March 12.

With every change in the bomber’s tactic, Austin residents are getting increasingly nervous.

Grocery stores, apartment buildings and restaurants have been evacuated at a moment’s notice as investigations intensify.

This time the explosion rocked a facility in the town of Schertz, in the San Antonio area. Reports said one employee was injured.

The Washington Post, quoting the FBI, reported that the package had been bound for Austin, the state capital.

Hundreds of police officers and FBI agents are searching for a mysterious "serial bomber" after Sunday's blast in Austin the fourth this month left two young men seriously injured and the city on edge.

Police said the explosion was connected to three previous bombings in Austin and the bomber used a tripwire in the latest attack, showing a higher level of skill.

"We're clearly dealing with what we expect to be a serial bomber at this point," Austin police chief Brian Manley told reporters. </s> An explosion at a South Austin Goodwill store on Tuesday evening injured a man in his thirties, according to Austin-Travis County Emergency Management Services. Austin police said the sixth blast in the Capital City this month was not a package bomb, but an incendiary device described as “an artillery simulator.”

“At this time there is no reason to believe this incident is related to previous package bombs,” police tweeted just after 8 p.m. Austin Assistant Police Chief Ely Reyes said the incident occurred just after seven Tuesday evening, when a Goodwill employee handled one of two of these simulators “that looks like some type of ordnance or some type of momento,” causing one to go off in his hand.

“We have no reason to believe that this was an attempt at a copycat,” Reyes said during a briefing Tuesday night.

But the massive emergency response, including the evacuation of a nearby grocery story and the “reverse” evacuation of a nearby high school (people were ordered into the building) demonstrated the growing angst that residents of the city are starting to face.

This was the area’s second explosion on Tuesday, part of a string of bombings that have killed two and injured four across Austin and in Schertz, northeast of San Antonio. Investigators said earlier Tuesday that the five previous bombs are connected.

Officials said the explosion happened on Brodie Lane near West Slaughter in far South Austin, about eight miles from Sunday’s blast in Southwest Austin.

The sixth explosion extends what has already been a tense day for residents and first responders in Austin. Early Monday morning, a bomb disguised as a package exploded at a FedEx facility in Schertz; there were no serious injuries. Investigators later found an undetonated bomb disguised as a package at a FedEx store near the Austin-Bergstrom International Airport in Southeast Austin, and confirmed that a package delivery store in Sunset Valley is believed to be the source of the bomb that exploded in Schertz. FedEx has cooperated with authorities and turned over to investigators information on the sender of the package, offering a glimmer of hope that the police and federal investigators who have struggled to find any clues leading to a suspect or motive may finally have something to work with.

Tuesday’s explosions came two days after a trip wire triggered a bomb that injured two men in Southwest Austin. On March 12, two separate packages exploded, one killing 17-year-old Draylen Mason and injuring his mother at their East Austin home, and the other injuring 75-year-old Esperanza Herrera in Southeast Austin. Anthony Stephan House was killed on March 2 when a package exploded at his home in Northeast Austin. Austin police chief Brian Manley has described the bombings as the work of a serial bomber. </s> Package addressed to Austin explodes at FedEx facility in Schertz

A packaged destined for an address in Austin exploded inside a FedEx distribution facility outside of San Antonio, law enforcement sources tell CBS Austin.

The package detonated around 12:25 am at the facility in Schertz, TX. Sources said the package was moving from an elevated conveyor belt to a lower section when it exploded.

A woman working near the package was treated for a headache but was not seriously hurt.

The package contained shrapnel consisting of nails and pieces of metal, sources said, but none of the 75 employees inside the facility were injured.

There are several law enforcement agencies at the scene, including agents from the ATF, FBI and Homeland Security.

This is a developing story. Please check back periodically for details.
