New details have been released regarding the deadly 1-car wreck on Casper's west side.

According to the Casper Police Department, speed played a factor in a 1-car crash at the intersection of 13th and King Boulevard, near the 3 Crowns Golf Course, that killed 24-year old Dylan Brock, back on Wednesday (October 12th).

The Department says all 4 occupants in the vehicle were not wearing their seat-belts.

Police are still trying to determine who was driving the 4-door Cadillac, which way it was going, and if there were any other contributing factors such as alcohol or illegal substances.

The names of the other 3 involved in the crash as well as their status, have not yet been made available, because the investigation is still on-going.
