"There was a young girl, laying right here. And she was -- I could tell immediately she was gone," said Sullivan, 19. "I saw a gunshot wound to her abdomen, also one to her side and one through her head."
She wasn't alone.
"There was a girl right here and she was really struggling. You could tell she was barely able to move her eyes and just moving her arms slightly," Sullivan said. "And there was another girl right here. You could tell she was lying down crouched. She was still conscious, talking."
By the end of the night, two of the three young women had died -- Katherine Cooper, 22, and Veronika Weiss, 19. Both were students at UC Santa Barbara.
Delta Delta Delta said on its Twitter page Sunday that it mourned the loss of two of its sisters.
"Tri Delta is saddened by the tragic loss of two members at UCSB. Our thoughts are with their family, friends, and Gamma Theta Chapter," the message said.
Alpha Phi posted on its Facebook page Saturday that "all our members are safe."
Rodger then zoomed around town in a black BMW, stopping at a delicatessen where he shot and killed Christopher Martinez, another UC Santa Barbara student.
Exactly why, no one knows for sure.
Rodger got back in his car, and the killing rampage continued.
He dashed around town, reportedly driving down the wrong side of the road so he could fire out the driver's side window near the sidewalk. He shot at two people on the sidewalk, pulled a handgun on a woman and fired some more, Brown said.
He encountered a sheriff's deputy who was on foot and exchanged gunfire.
Witness Ian Papa said he was inches away on the street when the gunman's car sped up and struck two bicyclists.
"It happened so fast," he said. "I had no time to react. I jumped on the sidewalk and I see a man on a BMW, his body inside the windshield and glass broken everywhere. ... I almost wanted to break into tears."
The nightmare finally ended after Rodger slammed into a parked vehicle and apparently shot himself in the head, police said.
By the time the melee was over, six victims were dead, 13 were injured, and a quiet beachfront community was left to wonder how this could happen -- and whether anyone could have prevented it.
In the nearly seven-minute video posted Friday, Rodger rants about women who ignored or rejected him over the past eight years, "since I hit puberty."
"Tomorrow is the day of retribution, the day in which I will have my revenge," he says in what he calls his last video. "You girls have never been attracted to me. I don't know why you girls aren't attracted to me, but I will punish you all for it." He specifically criticized sorority members.
It's unclear what Rodger might have done had he not wrecked his car. Inside the wrecked BMW, Brown said, police found three handguns -- all legally purchased -- and more than 400 rounds of unused ammunition. Brown said the guns were purchased the firearms over the past year in three different cities.
Martinez's father, Richard, said some politicians and the National Rifle Association are also to blame for his son's death.
"Chris died because of craven, irresponsible politicians and the NRA," he said. "They talk about gun rights -- what about Chris' right to live? When will this insanity stop?"
Rodger suffered from an undisclosed mental health issue and was under the care of a variety of health care professionals, Brown said.
But there was no indication he had been committed to a mental health facility.
