OMAHA, Neb. (AP) — An autopsy report says an Omaha man who officers say killed a police dog during a standoff died because of water on the brain and low levels of sodium and chloride in his blood.

Fifty-nine-year-old Mark L’Heureux (leh’-ROH’) died in custody on Feb. 2, more than a week after the 25-hour standoff with officers.

Officials say L’Heureux was examined at a hospital after surrendering on Jan. 23. He was mildly dehydrated, had some minor cuts and was diagnosed with cold exposure and psychosis.

L’Heureux refused to eat or take medications after he was released from hospital and placed in the Douglas County Jail.

Police say L’Heureux shot the dog, named Kobus, as officers tried to serve a warrant ordering L’Heureux to undergo psychiatric evaluation.
