A 42-year-old man choked to death early Sunday at Voodoo Doughnut on East Colfax Avenue in Denver.

Travis Malouff was pronounced dead at the scene.

The Denver Office of the Medical Examiner says he died of asphyxia, due to obstruction of the airway.

The Denver Police Department and Denver Health medical center declined to comment on the case. The Denver Fire Department said it responded to Voodoo Doughnut at 1:10 a.m., but a spokesman said he couldn’t discuss the incident further.

A manager at the store declined to comment on Monday evening.

KUSA-Channel 9 reported that witnesses say Malouff was doing a doughnut challenge before he died — trying to eat a half-pound doughnut in 80 seconds or less.
