Federal authorities are investigating a possible connection between a Madras homicide and the death of a man found in Warm Springs.

Madras resident Cody Custer Wallulatum, 29, was killed by a gunshot March 15. Two days later, the body of Gunner Johnson Bailey, 31, was found on the side of the road in Warm Springs. Authorities would not release Bailey’s cause of death but have opened a criminal investigation.

Jefferson County Sheriff Jim Adkins confirmed that authorities believe the two deaths are linked and the FBI is investigating.

FBI spokesman Kevin Sonoff said the deaths are being investigated by the bureau’s Indian Country Crime Unit.

“It’s still an active investigation, so unfortunately, there’s not much I can say,” Sonoff said.

Jefferson County District Attorney Steve LeRiche confirmed his office is working on an investigation related to Wallulatum’s death but declined to comment further. He said the Central Oregon Major Incident Team, involving representatives of various law enforcement agencies, has been deeply involved.

Just before 9 p.m. March 15, Wallulatum’s wife, ­Kaliska Wallulatum, arrived at the emergency room of St. Charles Madras with her husband, who was unconscious and the victim of a single gunshot wound to the lower left side of his abdomen, according to court documents. He was placed on a gurney and wheeled inside.

The wound appeared to come from a small-caliber bullet, according to court documents.

Doctors found no pulse and no blood pressure. He was given blood, but pronounced dead shortly after his arrival.

Kaliska Wallulatum said she was home when her husband came home injured. He sat down on their bed and told her he needed to go to the hospital, she told police.

She told an interviewing officer her teenage sons helped carry her husband to her two-door Toyota sedan. She said she didn’t know he had a gunshot wound until she lifted his shirt and saw a small hole in his abdomen.

Cody Wallulatum had twin teenage sons. A viewing of his body was held March 21 in Warm Springs.
