Now. Good evening. Tonight, we begin with a nation increasingly on edge as details slowly emerge about the San Bernardino shooters and the weapons they used to carry out their vicious attack. In an online radio broadcast today isis praises the two shooters and this comes as the president is ramping up his language saying the act was an act of terror. We have it all covered and we begin in redland, california. Reporter in this Bedroom Community outside los angeles, neighbors tell nbc news siyed farook and tashfeen malick appeared normal. Today the group isis praised the attack, calling the couple martyrs, but theres no evidence that the attack was directed by a militant group. Malik was born in pakista pakistan. She spent time in the Punjab Province in her early years and later went to university there which was a hotbed for recruiting. There was no signs she was involved with radical islamic groups. Some say u. S. Officials are right to ask if she radicalized her husband. I think Tashfeen Malik selected a clean candidate to be her cohort in terrorism. In duos, we have a primary actor who manipulates a more vulnerable subservient person. Reporter malik married farook after meeting in saudi arabia. He was born in chicago.

Thank you for that report. President obama met with his National Security team today for a briefing on the shooting investigation. Officials say theres no solid evidence tying this attack to any specific terror group. Our justice correspondent Pete Williams is following this angle. Pete, good evening. Kristin, good evening. The white house says the president was told today they found no indication that the couple was part of an organized group or terror cell. James comey says several factors suggest they were radicalized. Among them their extensive preparations, the way they built their bombs, and the pledge of support for isis that malik posted before the shooting. No sign at this point that the couple was in direct contact with anyone from any terror group. Investigators hope theyll discover the couples motives on the computers and cell phones they left behind, but the couple damaged those devices before the shooting. While the lab at washington is working overtime to recover that data, that work is slow going. Pete williams from our washington newsroom. Thank you, pete. We are learning more tonight about the four guns used in the massacre and where they came from. It turns out two of those guns, the assault rifles, were purchased by a friend of syed farook. Reporter the attack on the Holiday Party didnt take long. Roughly 75 rounds in just a matter of minutes. Overnight, Law Enforcement searched a house belonging to a friend of syed farook who they believe originally purchased the two assault rifles during the rampage.

Reporter the couple tried to alter one rifle to make it fully automatic, but their attempts failed. The law in the state of california says a magazine can only hold ten rounds, but the shooters had magazines that could hold 30 and they had them taped together. When magazine finished, all they needed to do was flip it and use the next one. Federal investigators took security video and financial records from this gun range. The couple may not have needed much practice. Law enforcement officials tell nbc news the man who originally bought the gun has not been able to tell them how or when they ended up in the couples hands. They say hes been too emotionally distraught to give them that level of detail. Just a fascinating look at assault rifles. We have a program note now. Chuck todd will have much more on the San Bernardino shootings tomorrow on meet the press. As we told you earlier, president obama spoke out again today about this weeks shootings and so did some of the president ial candidates.
