Autopsy says woman died from dog attack

Jan 8, 2015 - By Katie Roenigk, Staff Writer

Officials have concluded that no humans were involved in the November death of Deanne L. Coando-Tyvonnes, 40, of Fort Washakie.

Coando-Tyvonnes was found unconscious on the afternoon of Nov. 12 in the 800 block of Rendezvous Road. Reports at the time indicated she had been attacked by "multiple dogs," but Coroner Mark Stratmoen said some people suspected foul play.

"There was a lot of scuttlebutt going around in the community that somebody had assaulted her and dumped her, that kind of thing," Stratmoen said. "The investigation showed absolutely no evidence ... whatsoever of any other human involvement or suspicious circumstances."

Coando-Tyvonnes' cause of death is listed as exsanguination, or blood loss, due to multiple injuries from an animal attack; her wounds were consistent with those inflicted by dogs, according to her autopsy report.

Emergency responders at the scene could be heard describing Coando-Tyvonnes' wounds, which resembled deep lacerations like those inflicted by a knife, according to scanner traffic. A male responder said he couldn't tell whether she had been attacked with a knife or by an animal. In addition, emergency personnel said they had to stay at the scene after the woman was transported, because they had found footprints in the snow.

The incident has been labeled an accident. Coando-Tyvonnes' blood-alcohol content was .308 at the time of her death at about 10:20 p.m. Nov. 12. She was pronounced dead at SageWest Health Care at Riverton after being transported there by ambulance from the spot where she was found unconscious and with a weak pulse on the side of Rendezvous Road.

Responders at the scene were unsure whether Coando-Tyvonnes had been outside overnight, and they said she appeared to have hypothermia.

The temperature at the time she was found was near zero. Hypothermia was not listed as a cause of death on her autopsy report, however.

She was about 5 feet, 6 inches tall and weighed 160 pounds, with brown hair and brown eyes.
