Authorities in Colorado have arrested a Denver man on suspicion of murder for allegedly shooting a passenger in his car.

According to the New York Post, 25-year-old Michael Hancock was driving for Uber on June 1 when he picked up a rider identified as 45-year-old Hyun Kim.

Denver District Attorney Beth McCann said police recovered the passenger’s body from Hancock’s car the same day along Interstate 25.

An affidavit compiled by Denver authorities indicates Hancock told a motorist that his passenger attempted to attack him and admitted shooting the man in self defense.

The suspect had reportedly worked for Uber for about three years. The company has a policy prohibiting drivers from carrying firearms.

A corporate statement acknowledged the arrest, adding that it was “deeply troubled” by the allegations and had removed Hancock’s access to his account.

When police responded to the scene, they reportedly found a handgun in Hancock’s possession. They say 10 bullet casings were also recovered from the scene near the suspect’s vehicle.

Initial reports indicate Hancock did not answer investigators’ questions. His family, however, has turned to the media to defend him.

Kilisha Beasley claims her brother acted in self defense after his passenger beat him in his head, as reported by KDVR.

The suspect’s father called the charges against Hancock “ridiculous,” predicting that he will be exonerated.

“My son will be vindicated and unfortunately we’ll probably have to spend a lot of money to do that,” he said.

As of the latest reports available, he remained in jail without bail.
