Las Vegas teens charged with murdering retired police chief allegedly attempted to kill a second cyclist

A source told 8 News Now that the pair allegedly stole three cars, committed a burglary, hit and killed Pobst, and tried to run over a second cyclist over the course of two hours.

Alaya and Keys were arrested last week after a video went viral on social media of the teens appearing to intentionally drive a vehicle into a person riding a bicycle. During the video, which is seemingly filmed by a passenger in the front seat, a person can be heard saying, "Alright go, go go go," before sideswiping another car.

"B**** ass n*****!" One person yelled. "Stop talking sh**, b****!"

"Get his a**," one voice says just before the car hits a man on a bicycle. "That n**** knocked out!" one voice said afterward.

Ayala claimed to police that he would get a slap on the wrist for the incident. "You think this juvenile **** is gonna do some *****? I'll be out in 30 days, I'll bet you," he said.

"It's just ah ... ah, hit-and-run, slap on the wrist," he said, even though the cops never mentioned the incident to him.

On Wednesday, a judge ruled that the two suspects would be charged as adults in the Las Vegas Justice Court. Both have been charged with murder with a deadly weapon, battery, and attempted murder.

Authorities said Ayala was the alleged driver of the 2016 Hyundai Elantra, in the video and Keys filmed the disturbing video on a cellphone. The judge ordered the two to remain behind bars at the Clark County Detention Center for the remainder of their trial.

Metro Lieutenant Jason Johansson called the video "appalling" in a press conference Tuesday. He said the drivers "lacked morality."

Ayala's mother said, through a translator, that she doesn't know, if "God can forgive this." While Keys' mother said, "My son's side of the story will be told, ‘the truth,’ not the inaccuracies the media will try to portray."

Probst retired in 2009 after serving on the Bell, California, police force for 35 years. He was described as a "ray of sunshine" by his daughter.
