good evening. tonight, a deadly turn of events sparking even more distrust between the fbi and a group of angry militia men in rural oregon. one rancher killed and conflicting eyewitness accounts adding fuel to the fire in the nearly month-long armed standoff. tonight questions about how this will end. here's abc's neal karlinsky. >> reporter: authorities said it was supposed to be a careful and peaceful traffic stop. but instead it ended in the shooting death of robert lavoy finnicum. a takedown that left the leaders of his group handcuffed on the ground. tonight the scene has turned into a rallying cry for the armed occupiers at a remote wildlife refugug here w w t tk over this land in early january. they're calling lavoy a hero in the patriot movement. his picture now spreading online. wrongfully taken out, they say, enforcement.

>> reporter: the fbi and local police won't explain how it all happened or even name finnicum as the man killed by police gunfire. >> i'm disappointed that a traffic stop yesterday, it wawa supposed to bring peaceful resolution to this -- ended badly. >> reporter: but one alleged eyewitness says he was just walking with his hands in the air. >> he's like, just shoot me, then, just shoot me! and they did, they shot him dead. >> reporter: in an audio interview posted to youtube, victoria sharp, seen here in this video shot by abc news earlier this month at the refuge, says she was in the car with nnicum when it went down. >> he was just walking. with his hands in the air, i saw it. i swear to god. then after he was down on the ground, shot him three more times. like so much about the bizarre occupation, the story is not so clear. another alleged witness said finnicum was not executed -- >> he charged at law enforcement.

that nonsense. that was a miscommunication. >> reporter: one of the occupiers, pete santilly, live streamed his appppach to the fbi ockade after he heaea shots had been fire >> if they've taken ammon into custody, it's time for -- there's women and children up there, okay? there's women and children. we need go get them out. >> reporter: he was then taken into custody. >> they're surrounding us. there's no firearms in the car, please don't aim the rifle -- >> no one'e'aiming a rifle at you. >> this is a rimeter, you need to go back. . >> reporter: f fm the beginning police found this strange standoff challenging, fearing a bloodbath if they moved in too quick. >> any timi you have people dug in that are armed and that they are making certainty manneds s demands and saying they're not going to leave until they get those demands the you've set up a dynamic where there's a potential for violence,

is there a way to back out of that? >> reporter: while we still don't know the details of the deadly traffff stop, finnicum himself almost seemed to predict tensions were about to escalate. in an interview just posted by "the oregonian" by youtube. >> the tenor has changed. they have become more hardened. they're doing all the things that shows that they want to take some kinetic action against us. they do not intend on losing here. and we do not intend giving it back to them. >> reporter: but tonight the area's on lockdown, now sealed off by heavily armed fbi s.w.a.t. teams at roadblocks eight miles out. as we found out when approaching. >> you need to go back out and stay outside that sign, please. >> okay, will do. well, those guys meant business. >> reporter: in all, eight key members of the occupation are under arrest, facing a federal charge of conspiracy to impede u.s. officers by use of force. ammon bundy, the leader of the

in a surprisee move his lawyer called for an end to the standoff. >> right now i'm asking the federal government to allow the people at the refuge to go home withwut being prosecuted. >> reporter: words he says bundy wanted him to share. >> to those remaining at the refuge, i love you. let us take this fight from here. please stand down. >> reporter: but the circumstances of finnicum's death could be making the occupiers nervous. >> they told us that we could safely leave. well -- the group that was leaving has a dead man in it so it depends on what you believe. >> reporter: the standoff began in early january when several dozen militia men, led by bundy and finnicum, took over the remote refuge when no one was there. >> this refuge here is rightfully owned by the people. and we intend to use it. >> reporter: bundy said his group was fighting for the return of thousands of square miles of federal land to

for freedom for two other nchers convicted of lighting fires on federal land. >> i'm going to jail for five years for 127. seems like a bit of an overkill. >> reporter: when we first visited the compound, despite the fact that many were armed, it was seemingly peaceful and law enforcement was keeping their distance. >> this is the sanctuary they've taken over. you can see their guard tower inn the distance ovevethere. and here youeally donon see a lot of presence at all. and they have gasoline, actually, fuel pumps for their vehicles. >> reporter: inside, bunks the militia members slept on. a woman preparing meals. at the time, ranchers were pleading for others to join their cause. >> we need you to get here and stand with us. whether you're armed or unarmed, get up here. >> reporter: finnicum, a grandfather of 19, traveled here from arizona and said he was from a long line off ranchers. >> theirivelihood is being threatened, their economic ability to ranch is being squeezed, and they're being

their way of life, generational. >> love you, support you! >> reporter: lavoy had been in trouble with supports before, joining rancher cliven bundy in a 2014 face-off with federal agents over cattle grazing rights. >> back off! >> reporter: when i met him, he told me he was willing to die for the cause. >> how did we get here in the first place? was there not people who gave their life to us? was it not a great gift, a great sacrifice? it certainly was. you love your wife, kids, you give them a hug. and if i see them on the flip side, i see them on the flip side. >> reporter: today there's growing concern that finnicum will become a martyr for extremist groups. many of his supporters voicing their anger all over the internet. nevada assembly member michelle fiori tweeted her support, referring to his death as murder. my heart and prayers go out to lavoy lavoy's family. he was just murdered with his hands up in burns, oregon.

the comes days may be critical in how all this gets resolved. >> i think what the government does not want to do is get into an excessive force situation. where they basically raid this refuge and physically remove people who are armed, who may well try to shoot at them, whihi will p pbably result in thehe getting shot. >> reporter: reports tonight that only a handful remain and they are being encouraged by nearby patriot groups to end the siege. the sheriff made it clear today that their time is up. >> it's time for everybody in this illegal occupation to move on. we don't arm up and rebel. this can't happen anymore. this can't happen in america and it can't happen in harny county. >> repororr: for "nightline,e, neal karlinskykyn burns, oregon. up next, the miami doctor captured on video lashing out at the uber driver. the attack spreading like wildfire online.

my father was actually placed in the hospital. i just recently broke up with a boyfriend. >> literally that evening? >> minutes prior to. and that's w w i decided to leave my car there. i'd taken a couplef drinks and i was trying toatch an uber to get home. >> reporter: the driver, igor bellic, speaking to wtvj. >> she was erattic, screaming, cursing. >> reporter: he waits for police to arrive. >> good night! >> reporter: that's when angeli says she started trying to make amends. >> i apologized that night to him after we settled and i paid him for the damages. he accepted my apology and i was very grateful he didn't press any charges. >> a lot of people are saying because he didn't press charges that you're getting away with it. >> i don't believe that i got away with it. it was his idea, okay, if you pay me for the damages, everything will be fine. i had no further problems with him that night. >> reporter: but once the video started exploding on the internet, the judge and juries on social media began weighing
