Uber driver arrested after fatally shooting passenger in Denver, motive still unknown

Denver police say an Uber driver who fatally shot a passenger has been arrested.

Police say 29-year-old Michael Hancock was arrested Friday on suspicion of first-degree murder in the shooting on an interstate.

Authorities say Hancock shot a man in a car shortly before 3 a.m. after some kind of altercation, and the man later died at a hospital. Police haven’t released any other details about what led up to the shooting.

Hancock hasn’t been charged, and it’s not clear if he has a lawyer.

It will be up to prosecutors to decide whether or not to pursue a murder charge or any other criminal charges against him.

Uber says it’s “deeply troubled” by the fatal shooting. The ride-hailing company says in a statement Friday that its thoughts are with the families of all those involved and that it will continue to work closely with police.
