The Boulder County Coroner’s Office has identified the two men killed in a crash on Diagonal Highway Monday night as Brock Borman, 56, and David Vollmar, 53.

Both men are from Boulder, according to the release from the coroner’s office.

The crash occurred about 11:20 p.m. Monday at the intersection of Diagonal Highway and 34th Street, according to a release by Boulder police.

According to police, a BMW sedan driving west on Diagonal Highway made a left turn at 34th Street in front of a Nissan Altima driving east, leading to the collision.

No charges have been filed at this time, and Boulder police spokeswoman Dionne Waugh said Thursday the “investigation is still ongoing as we await further information.”

Anyone with information about this crash is asked to call Boulder police Officer C. Shepherd at 303-419-9943 and reference case No. 21-06561.
