BOULDER — Residents of Mapleton Hill say Boulder police shot and killed a large bull elk near Ninth Street and Mapleton Avenue late Tuesday night — but no one from the police department, Boulder County Sheriff’s Office or Colorado Parks and Wildlife has any record of the incident.

Jennifer Churchill, a spokeswoman for Colorado Parks and Wildlife, said her office would investigate. “This is a large game animal and a trophy animal,” she said.

The elk appears to be the same one that reportedly trapped a mail carrier on a porch in the area last week and was photographed by a Camera photographer later that evening. Neighbors said the elk continued to frequent the area along Mapleton between Ninth and 11th streets and behaved aggressively toward passers-by.

Roger Koenig said he saw people approach the elk with their cellphone cameras repeatedly Monday night. The elk would lower its head and begin to charge.

On Tuesday night, Koenig said, the elk was in his front yard around 11 p.m. when people who appeared to be Boulder police officers arrived and told his wife that they might put down the animal and that she shouldn’t be alarmed if she heard a gunshot. A short while later, they heard a gunshot and went outside and saw the dead elk.

Koenig said the animal was removed quickly, apparently with the assistance of what appeared to be deputies from the Boulder County Sheriff’s Office.

However, officials with the Boulder Police Department and the county sheriff’s office said Wednesday they have no record of responding to a call about an aggressive elk or of an officer discharging his weapon that night.

Boulder police spokeswoman Laurie Ogden said officers who discharge their weapons have to document the reason for firing, regardless of the circumstances, but no one has any record of any incident involving an elk late Tuesday.

However, neighbors described several police vehicles with their lights on in the area Tuesday night.

Churchill said Colorado Parks and Wildlife also had no record of the incident. State wildlife officers were not involved, she said.
