(CNN) -- One of the three guns Adam Lanza used to kill 20 children and six adults at an elementary school in Newtown, Connecticut, was a military-style semiautomatic rifle known as an AR-15. That surprised and shocked a lot of people unfamiliar with America's gun culture. They questioned why such weapons are available and why anyone would need them. "Personally I don't know how any ordinary citizen can justify owning an automatic or semiautomatic gun," writes CNN commenter Mark Smerkanich. "Can't we leave those guns to the trained military?" Self-described gun owner Julie Jones-Hawkins comments, "I ... fully support a ban on rapid-fire weapons. Any weapon that can take out an entire kindergarten class is a problem." Here are five reasons many gun owners say they want military style rifles: . 'Some people play golf, others bowl. I shoot' "Every month or so I take my guns out to the range and shoot. It's thrilling, exciting and a great way to vent," says Christopher L. Kirkman, a Florida-based military-style gun owner. Kirman was one of more than 100 gun enthusiasts who shared opinions on CNN iReport about owning firearms that would have been banned under the now-expired 1994 federal weapons ban. "Sure, I could try to say that the reason I own these guns is self-defense, but the truth of the matter is that, although they will technically serve this purpose, they are not why I own them," he says. Michigan gun owner Ethan Daniels describes his enthusiasm for his rifle more succinctly, saying, "I like to shoot, and that is one heck of a fun carbine to plink with." iReport: Tell us why you own your military-style weapon . Background can factor into a gun owner's choice of weapon. "The AR-15 is what I am used to from my extensive training as an airborne infantryman," writes Nathan Lee. "Because of my training, it's what I feel the most comfortable with." Another reason for these guns is hunting. The AR-15 is a "good hunting platform. I've hunted coyote with it," says CNN iReporter MVR155, who owns two of the weapons. He asked to remain anonymous. Owners of military-style rifles also use them to hunt deer and other game. But some states have banned the AR-15 and its .223 caliber for deer hunting. Related: Newtown shooter's guns: What we know . 'It's cool' It may not be the best or most important reason, but military-style weapons often appeal to the enthusiast side of the American gun owner. Just like many car lovers who dream of owning a Lamborghini, many gun owners get excited about the idea of owning an AR-15. "There are people who buy certain types of firearms because they have a certain image -- the AR-15 is one of them," says Austin Nikel, a former AR-15 owner in Boulder, Colorado. "One thing about this country is how Hollywood has glorified the image behind those certain types of weapons. A lot of guys grow up with GI Joe, and that image is extremely attractive. It grabs you and affects you. "A lot of people buy the AR-15 because, well, it's cool." Apparently it wasn't cool enough for Nikel to hold on to. He ended up selling his AR-15 to his father. iReport: Why some own military-style weapons . 'A part of history' "Since coming of age -- and in the decades since -- I have collected many different firearms, some of them historical pieces, some for sport, some of them even the so-called 'assault weapons' that are now a controversy," says iReporter Hrothgar01. "Guns like these are as much a part of the history of this country as the muskets carried by pioneers, the rifles toted by doughboys in the trenches, and the other arms that have served and protected throughout the years. To hold one in your hands, appreciate its history and design, and to be able to take that piece of history to the range and work -- it is a feeling that many people in this debate do not understand or appreciate." Related story: By the numbers: Guns in America . 'Protecting my family' "I believe the foremost person responsible for protecting my family and myself is me," writes iReporter ShortyDoowap, who owns a pair of AR-15s. "These rifles provide me with the tools to perform that duty. I don't own these guns to target shoot, though I do that with them. I don't hunt with them, though I could in a pinch." Parks says he "would not hesitate to use one to simply defend my home and family from a single intruder if it became necessary." Related: Parents defend right to keep guns in the home . In some home-protection situations, fans say military-style rifles are generally more accurate than handguns. Rifles are generally easier to learn how to shoot, say military-style rifle owners. Like most firearms, military-style weapons such as the AR-15 are semiautomatic -- increasing protection because the shooter can fire off many shots without having to manually chamber a new bullet. With a bolt-action rifle or pump-action shotgun, firing multiple shots takes more time. "When you weigh it all out, these types of guns are stigmatized," says iReporter MVR155. Military-style weapons look more dangerous than other guns, he says, but really, there are many weapons available which are just as lethal, but which are not designed in a military style. iReport: One gun owner's solution . 'Fascination with the Second Amendment' "I am a proud owner of an AK-47," writes iReporter INGunOwner. "It's a terrific gun. Lots of fun to shoot. I own an AK because of my fascination with the Second Amendment, which I view as a backstop protector of freedom. Many people would argue that we have no use for it today because the government is trustworthy. "However since it acts as a deterrent, we can never measure exactly how much it has been effective. Perhaps the notion that people feel safe with our government after over 200 years is a testament to the Second Amendment value in balancing power with the citizens."

(CNN) -- A Florida exterminator and father of four children adopted from Florida's foster care system has told police that a body found in the pest-control truck he was driving is one of them -- his 10-year-old daughter, authorities said Wednesday. Jorge Barahona, 53, already faces a charge of aggravated child abuse for injuries to the dead girl's twin, Victor, who was also found in the truck, which was parked on the side of I-95 near West Palm Beach, Florida, officials said. According to a probable-cause affidavit filed by the West Palm Beach Police Department, a roadside assistance ranger with the Florida Department of Transportation stopped to check the red Toyota pickup Monday around 5:30 a.m. and found the 10-year-old boy inside next to an open gas can. The boy "appeared to be in respiratory distress and (was) trembling" and his clothing "was soaked with an unknown chemical," the affidavit said. The ranger then found Barahona on the ground beside the truck and called for help. The boy was hospitalized in intensive care with severe burns to his abdomen, upper thighs and buttocks, the affidavit said.  While examining the boy, doctors noted he had sustained previous injuries, including a broken collarbone, a broken arm, scarring to his buttocks and lower abdomen, and ligature marks on both wrists, police said. After Barahona and his son were taken to a hospital, a worker decontaminating the truck discovered the body of the girl, wrapped in a plastic bag, the document said. Barahona told police he was distraught over the death of his daughter, and had intended to commit suicide by dousing himself with gasoline and setting himself afire, the affidavit said.  Barahona said he didn't go through with his suicide plan because his son was with him, the document added. "Basically, to paraphrase, he was stating that he placed his daughter in a plastic bag being distraught over her death," West Palm Beach Police Spokesman Chase Scott told reporters. "He drove here from South Florida accompanied by his son, Victor. He then pulled off to the side of the road saying that he poured gas on his self, intending to light himself on fire. His son's head was in his lap and he decided, after giving his son some sleeping pills, that he wasn't going to do that." Barahona told police that he doused himself with gasoline and inadvertently got some on the boy, Police Capt. Mary Olsen said. But, she added, the man's story doesn't add up -- there was no gasoline on the boy. Instead, he was covered with another chemical whose composition had yet to be determined. "That's why we're still treating this as a hazmat (hazardous materials case)," she said. Scott said the chemicals were so potent that staff caring for the boy at the hospital became ill as well, he said. Victor, who was transferred Wednesday morning to a specialized burn unit at Miami's Jackson Memorial Hospital, has not been able to talk to investigators because he is on a breathing tube, she said. Olsen said police would decide how to charge Barahona further once the autopsy on his daughter determines her cause of death. Asked whether Barahona has expressed remorse, she said, "He feels remorse, but we're not getting consistent statements with what we're seeing in our evidence." She added, "It's a complex case." At a hearing Wednesday in Miami attended by Barahona's wife, Carmen, a judge ordered that the remaining two children in the home be placed in foster care. Florida's Department of Children and Families had opened a child protection investigation within the past few days to look into a complaint involving the Barahona family, and it wasn't the first such complaint, spokesman Mark Riordan said. Reporters in the courtroom Wednesday heard tales of abuse, mainly concerning the twins, from state officials and experts.  The caller to the child protection hotline in the latest case reported that the twins were routinely locked in a bathroom for long periods of time and had been bound with tape, the court heard. The story was corroborated by interviews with the other two children in the home, officials said in court. An investigator told the court that she had showed up last Friday night at the family's home but had not seen the children. Instead, she said, she had left the family's house after speaking with Carmen Barahona, planning to return on Monday. Asked why she had not planned to return sooner, she said, "I'm not allowed to do investigations on a weekend." However, a spokesman for the department, John Harrell, said it is the job of investigators to follow through immediately or refer to someone else in the department to follow through when a matter is urgent.

(CNN) -- Sawyer Jones kept asking if the tigers could get out of their enclosure. The 3-year-old boy was with his family at the San Francisco Zoo on Tuesday to enjoy a brisk holiday morning with the animals. A tiger dozes in the sun as Matthew Jones poses with his son Sawyer during their zoo visit Tuesday. Sawyer's father, Matthew Jones, said he was sure the tigers couldn't escape from their zoo exhibit. He never could have guessed it would really happen. Just a day after a tiger mauled one person to death and injured two others at the zoo, the elder Jones, of Menlo Park, California, was in shock. "I assured him they couldn't," Matthew Jones said. "I felt no reason for concern. I'm very curious to find out how the animal got out." The family visited the zoo Tuesday morning and left before 1 p.m. The coincidence was unsettling. "We couldn't believe that we were there just a few hours earlier," Matthew Jones said. The deceased victim has been identified as 17-year-old Carlos Sousa of San Jose, California, the San Francisco medical examiner's office said Wednesday. Matthew Jones said that after many trips to zoos around the country, he thought this zoo was "perfectly adequate" and saw nothing odd about it. He also thought it was highly unlikely that a huge tiger would be able to climb out of the enclosure. View CNN.com readers' photos of the tiger exhibit » . Other zoo visitors weren't so sure. Jina S., of San Jose, is questioning the nervous jokes she used to make about the tigers trying to jump out. Jina said she had always felt slightly uneasy about the pit surrounding the exhibit. She and her husband made comments about the tigers in the enclosure during their December 1 visit. "When we were there, we were discussing how it wasn't much of a stretch that they could jump over that gap," she said. "We were joking at the time, and it's horrible it happened to [Sousa]." But Jen Williams of Hollister, California, said she felt safe during her June 2007 visit and didn't think the animals could jump over anything. She says that keeping animals in zoos brings some risk to what is generally a safe environment. "It's always scary when you go someplace where there's large animals in captivity," she said. Steven Arnold of Mountain View, California, echoed Williams' sentiments and said tigers are wild animals that can do wild things, even in captivity. He has been going to the zoo for years and said he always thought it was theoretically possible for the tigers to escape their exhibit. "They're pretty spectacular animals when you see them up close," Arnold said. "They're huge. They don't remind you much of a house cat when you're seeing them up close." As at several other zoos, patrons are invited to watch the tigers get meaty meals. Arnold describes the feedings as "a big spectacle" where visitors can get fairly close to the animals. Tigers' animal instincts become more apparent at these events, he said. "[Zookeepers] feed them raw meat," Arnold said. "They definitely give you the impression of being wild animals." Reflecting on the mauling, Williams said she will continue to go see the animals and added that she's observed that renovations go on all the time. "I guess it's just a risk you take, but it's very sad." E-mail to a friend .
