>> yesterday a tragedy occurred in san bernardino. >> reporter: this massacre marking yet another instance of president obama speaking out about a mass shooting in america. >> going to have to i think search ourselves as society to make sure that we can take basic step s steps that would make it harder -- not impossible but harder -- for individuals to get access to weapons. >> reporter: the san bernardino shooting is the 355th mass shooting this year according to mass shooting tracker group that counts shootings where four or more or injured or killed by gunfire, more shootings than days this year. reality sinking in for the families of those 14 killed. >> we know he's in a better place. >> reporter: among them, nicholas thalasinos, employee of the county of public health. >> i got a hug and kiss from him yesterday, that's what i'm

>> reporter: aurora godoy, shannon janson. >> right now we're just great to feel god that she's alive, knowing that she's okay, she's going to pull through, makes it a big sense of relief. >> reporter: for those who lost their loved ones there is no relief, only unrelenting heartache. >> i have no idea how i'm going to handle this. the world will is ufr from having one less person like him in it. that's what bothers me. is, you know, he is a ray of light to so many people. when we come back, we hear from the survivor who worked with, even shared a cubicle, with one of the alleged killers. and the moment he knew something was horribly wrong. >> i'm ready to leave. and there's like a bomb went off. what about my family?

and what if this happened again? i was given warfarin in the hospital but i wondered if this was the right treatment for me. then my doctor told me about eliquis. eliquis treats dvt and pe blood clots and reduces the risk of them happening again. not only does eliquis treat dvt and pe blood clots, but eliquis also had significantly less major bleeding than the standard treatment. knowing eliquis had both... turned around my thinking. don't stop eliquis unless your doctor tells you to. eliquis can cause serious and in rare cases fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. if you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. while taking eliquis, you may bruise more easily... and it may take longer than usual for bleeding to stop. seek immediate medical care for sudden signs of bleeding, like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. eliquis treats dvt & pe blood clots. plus had less major bleeding.

patrick bacari shared a cubicle with one of the alleged shooters who he considered a friend. he was sitting next to syed yesterday. he told david muir everything seemed normal until he excused himself to go to the bestrestroom, then the blast of bullets. >> this was a guy you shared a kubel with for how long? >> about two years. >> you'd been sitting at the table with him? >> a very long table, he was at the op site end, i was at the other end. i think he came late so he positioned himself there. >> did you talk to him? >> just a nationalcasual nod or whatever. they announced a 15-minute break. during that break i excused myself and got to the restroom. and there's like a bomb went off. i turned back and looked at the mirror. i'm bloody here, here, here. i don't know what it is. >> you were at the paper towel dispenser? >> in the restroom, just pulled

pulled the towels, thought an explosion went out. i announced to the restroom we were under attack. got down on the floor, we put our feet against the door to inhibit anybody from entering. they're hearing gunfire take place. we're not feeling anything. i'm trying to contact my wife and tell her i love her. and that i'm okay. but we're under attack. the gentleman beside me, i asked him to call the police and he did. within minutes of us being there, i guess it was four or five minutes, they came and they attempted to open the restroom door but they couldn't move the door because we had the braced closed. >> with your feet? >> yeah. >> you were froze someone. >> we followed their directions. they took us across the -- that building to another building. they asked who's injured. one of my co-workers was outside that restroom and she took two or three rounds. and so we could see the injuries

i could feel my little bit of bleeding. some pepper marks all over my body. and so we said, you know, we've got to get her to an ambulance. >> reporter: patrick, also a medic, helped many of his co-workers who were wounded. today at the hospital he saw one of them, a woman who was shot, who he helped survive. >> did she thank you? >> yes. she said, this is the man that rendered me aid. and that made me feel good. >> your friends who were at that table? >> yes, i had very good friends. a very good friend who lives down the street. he had been the sweetest, most dear, most appreciated employee i've met while i worked there. he -- he was just a jack of all trades. and a blessing to be and to know. and he'll surely be missed. >> reporter: our thanks to david muir for that report. now we turn to the young couple alleged to have carried out the

after sweeping their house police found an arsenal big enough to kill thousands. rifles, pipe bombs, a chilling assortment of ammunition. abc's chief investigative correspondent brian ross takes us inside the search for answers. >> reporter: the fbi tonight is now treating the investigation of syed farook and his pakistani-born wife tashfeen malik as a potential case of terrorism, although without saying that was the motive. >> it would be irresponsible and remature repremature to call this terrorism. the fbi defines terrorism very specifically. that is still the big question, what is the motivation for this. >> jimmy: >> reporter: today behind the doors of the young couple's san bernardino home, police say they found an arsenal of weapons that could have been used to kill thousands of people. >> clearly they were equipped and they could have continued to do another attack. >> reporter: in the garage a virtual bomb factory with 12 unexploded bombs. described as similar to this one featured in an al qaeda publication. one neighbor said another

worried about what was going on in the garage. >> they had i guess -- receiving packages, quite a few packages in a short amount of time. and that they were actually doing a lot of work out in the garage. and she was kind of suspicious. >> reporter: but nobody called the police. also in the search, police found more than 6,100 unspent rounds or bullets found at the home. and in the getaway car. along with two high-powered assault rifles and two handguns. all purchased legally and quietly stockpiled by farook prior to the deadly assault on a holiday party for his fellow work frerls the county health department. >> he was there early on and he left. we did have some initial information that he left under some kind of duress or as if he was angry. >> reporter: farook came back with his wife, dressed in tactical gear, and marched into the meeting room and opened fire. not aiming at anyone in particular.

bullets so i don't know that there was any one person that they ultimately targeted. they killed 14 people there. >> reporter: the san bernardino police chief said it was clear to him that what happened was much more than simple workplace violence. >> nobody just gets upset at a party, goes home, puts together that kind of an elaborate scheme or plan to come back and do that. there was some planning that went into this. >> reporter: farook, upon in chicago, to all outward appearances lived a quiet life. he had worked five years at the county health department. one of his victims was fellow health inspector nicholas that will hasthalasinos, whose life said farook gave no signs anything was wrong. >> they all knew him. most of the victims, the victims i'm aware of, they were all friends with the man that did this. and even though they knew he was muslim, they had no idea that he had become radicalized.

>> reporter: on muslim dating sites farook described himself as devout and looking for love, seeking a wife who would wear a hijab. he called himself a liberal interested in snowboarding, working on cars, and taking target practice in the backyard. at the san bernardino mosque he regularly attended the imam said tonight the community was shocked by what happened. >> the news of the shooting was shocking. unbelievable. unfathomable. left us all speechless. and it is an act that we condemn as muslims. >> reporter: as for farook's wife, she is also a mystery to authorities tonight. and it's not clear how they first met. >> we don't know enough. we do not know enough. >> reporter: she came to the u.s. with him in 2014 from saudi arabia on what's known as a fiance visa and this marriage certificate shows they married on august 16th, 2014, in riverside, california. when their daughter was born,

registered for baby gifts asking for pampers diapers and an infant car seat. yet on wednesday they left all that behind. as farook took the wheel of the suv, rented just a few days earlier. his wife sat in the back, firing dozens of rounds as the police closed in and ultimately killed them both. now the fbi is looking for connections between farook and at least two specific individuals here in the united states who may have been involved in the radicalization of farook or in the planning of the attack. but bottom line the fbi says it is still too early to call this an act of terrorism. byron? >> thank you, brian. we'll be right back. >> this special edition of "nightline" is brought to you by geico. good thing geico offers affordable renters insurance. with great coverage it protects my personal belongings should they get damaged, stolen or destroyed.
