Investigators do not yet know if Tashfeen Malik radicalized husband Syed Farook, but he traveled to Saudi Arabia in 2013 for a long vacation 
 
 The husband and wife who shot dead 14 people in San Bernardino, California, last week were both radicalized “for quite some time” and spent time at shooting ranges, the FBI said on Monday. 
 
 FBI assistant director David Bowdich said that Syed Farook, 28, and his wife Tashfeen Malik, 27, were radicalized long before they went on a rampage at a community center in southern California last Wednesday, but would not specify whether he meant months or years.

 Bowdich said investigators do not yet know what role Malik had in the radicalization of her husband. 
 
 “How did that [radicalization] happen is the question,” Bowdich said. “And by whom, and where did that happen? And I will tell you right now we don’t know those answers at this point.” 
 
 A Pakistani citizen who emigrated to the US on a “fiancee visa” in 2014, Malik spent most of her life in Saudi Arabia and reportedly practiced an austere form of Islam. The American-born Farook traveled to Saudi Arabia for what coworkers described as a long vacation in 2013, returning the next year with Malik. 
 
 Before the shooting, the couple apparently practiced their firearm skills by visiting firing ranges in the greater Los Angeles area, Bowdich said, including once “within days” of staging their attack. 
 
 He added that bomb experts had found a total of 19 pipes for improvised explosives in the couple’s arsenal, more than the dozen originally thought. 
 
 John D’Angelo, an official with the Bureau of Alcohol, Tobacco and Firearms, also revealed new details of the arsenal that the shooters had amassed before the attack. He said that the shooters possessed five weapons in total, bought between 2007 and 2012. They included two handguns and a rifle purchased legally by Farook, and two assault-style rifles purchased legally by an acquaintance of Farook’s, named Enrique Marquez. 
 
 
 
 D’Angelo added that investigators were not sure how those rifles reached Farook and Malik from Marquez. Bowdich said he was “not prepared to discuss Mr Marquez at this point”. 
 
 The Los Angeles Times reported on Monday that Marquez entered a mental hospital after the attacks and has met with investigators, law enforcement sources told the paper on condition of anonymity. 
 
 Investigators have no evidence that anyone beyond the shooters was involved in planning the plot, Bowdich said, nor that last week’s attack was linked to anyone outside the continental US. The FBI is “looking at these two individuals and we are working to build it out from there”, he said. 
 
 During an address to the nation on Sunday night, Barack Obama also said there was no evidence of a “broader conspiracy here at home”. 
 
 The agency “did not have an open investigation into Farook at the time of this incident,” he added when asked about past suspicion surrounding the man. 
 
 Police and the FBI have conducted more than 400 interviews in the five days since the couple carried out the attack, which was declared an act of terrorism by the agency.

 In public and private, officials have said that the shooters’ “digital fingerprints”, including a reported Facebook post pledging allegiance to the jihadi group Islamic State, led them to the conclusion that the couple were inspired by extremist groups. Investigators have said that the couple attempted to destroy some digital media, but not said the couple used any encryption techniques to disguise their planning. 
 
 Family of the couple have similarly expressed shock, confusion and horror that their relatives could have carried out the attack. A coworker killed during the attack had an argument with Farook about Islam, according to one of the victim’s friends, but colleagues and siblings alike described the gunman as a quite and polite man – and the happy father of a six-month-old daughter. ||||| MULTAN, Pakistan — The Pakistani woman who carried out the mass shooting in California along with her husband last week had earlier spent a year studying at a conservative religious school for women in this southern Pakistani city, officials said Monday. 
 
 Officials at the Al Huda center in Multan said that the woman, Tashfeen Malik, enrolled in an 18-month course to study the Quran in 2013, just as she completed a degree in pharmacology at a nearby public university. But she left before finishing the course, telling administrators she was leaving to get married. 
 
 A national spokeswoman for Al Huda, an international chain of religious schools geared toward educated and often affluent women, said that Ms. Malik stopped her religious studies with the group in May 2014. A few months later, she was granted a K-1 visit that enabled her to travel to the United States, where she married Syed Rizwan Farook, according to American officials. 
 
 The couple had a baby girl six months ago. Then, after covertly amassing a stockpile of ammunition and homemade explosives, they attacked a holiday party last week at a social services center in San Bernardino, Calif., killing 14 people and wounding 21, the authorities say. ||||| These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to.

– The husband-and-wife team that murdered 14 people in San Bernardino, Calif., last week had apparently been "radicalized" for a good while, the New York Times reports. "We believe that both subjects were radicalized and for quite some time," says FBI assistant director David Bowdich. He adds that the killers, Syed Rizwan Farook and Tashfeen Malik, "participated in target practice in some ranges" in the Los Angeles area including "one occasion [that] happened within days of this event." But Bowdich says their path to radicalism isn't yet clear, the Guardian reports. "By whom, and where did that happen?" he asks. "And I will tell you right now we don’t know those answers at this point." In other developments: The killers' "digital fingerprints"—including apparent support for ISIS on Facebook—gave them away, according to officials. Seems the pair tried and failed to wipe away their digital trail. Officials are investigating Farook's friend, LA-area resident Enrique Marquez, who apparently bought two guns used by the couple, the LA Times reports. Marquez was in a mental hospital after the attack. Malik recently attended a religious school in Multan, Pakistan, the New York Times reports. Called an Al Huda center, it's part of a worldwide chain that teaches conservative Islam to women. It apparently doesn't teach violence, but imparts "a strong dose of 'Muslims are destined to lead the world' and 'the corrupt West must be confronted,'" says Husain Haqqani, former Pakistani ambassador to the US. Farook's father says he was shy and studious but "obsessed with Israel."
