Two teenage boys believed to be behind the sick hit-and-run homicide of a retired police chief in Las Vegas have been named as they are charged as adults. 

Jesus Ayala, 17, and Jzamir Keys, 16, are suspected of intentionally striking Andreas Probst, 64, while he was riding his bicycle down an empty highway in the northwest of the city at around 6am on August 14. 

Ayala was arrested the same day, accused of being the motorist behind the wheel of the 2016 Hyundai Elantra which hit the retired cop. 

Meanwhile Keys, who was detained this week following a police appeal for information, is believed to be the passenger who goaded the attack and filmed a sick video. 

The duo were transferred to the Clark County Detention Center on Wednesday and they will face charges of murder with a deadly weapon, battery and attempted murder in Las Vegas Justice Court, according to local reports. 

They appeared in separate hearings on Wednesday morning in Family Court, per the Las Vegas Review-Journal. DailyMail.com has contacted police and the attorney's office for confirmation and for photo identification of the suspects. 

Two of Keys' relatives cried during his first appearance in court in front of Hearing Master Timothy Andrews. 

One of Ayala's female relatives also attended his appearance before Hearing Master Randall Forman and used the assistance of a translator. 

She shielded her face and held back tears as she walked past reporters outside the courtroom afterwards, according to the Journal. 

Police said they also tied the teens to at least three hit-and-run incidents the same day. They believe the slaying of Probst, a former police chief in Bell, California, ended the spree.

Graphic video shows a dashboard view from the front seat of a vehicle approaching Probst from behind while he was riding near the curb on an otherwise traffic-free road. 

Laughter and comments from inside the car are heard before Probst, wearing a red shirt and dark shorts, was struck and thrown against the windshield.

A final image from the moving car shows the retired top cop on the ground beside the curb. 

Deputy Police Chief Nick Farese called the 'intentional' hit in a stolen vehicle and the sick video 'a cowardly act that in my 22 years of law enforcement left me personally appalled'.

At a news conference Tuesday, Taylor Probst described her father — known by loved ones as 'Andy' — as a man of honor and integrity who worked for more than 35 years in law enforcement.

'We are devastated by the senseless murder of Andy,' she said. 'Andy's life was robbed by two individuals who did not believe that lives of others matter.'

Probst urged the DA's office to 'take these crimes to the furthest extent of the law'.
