YAKIMA, Wash. -- A White Swan man accused of killing a Cheney marijuana store employee has been charged with killing a man on the Yakama Nation reservation in 2016.

Donovan Thomas Culps, 36, was indicted by a federal grand jury in April on a first-degree murder charge in the death of 20-year-old Neil Cloud in summer 2017. George Skyhawk Thompson was named as a co-defendant in Cloud’s death.

Federal court documents also show that Cloud, whose remains were recently identified by the FBI crime lab, was a suspect in the death of Felina Metsker, whose body was found near White Swan in May 2016, a month after she was reported missing.

The cases are in federal court because the victims and suspects are Native Americans and the crimes are alleged to have occurred on the reservation.

Culps is awaiting trial in Spokane County Superior Court on a first-degree murder charge in the death of pot shop worker Cameron Smith in 2017. In an October 2017 interview with a KHQ-TV reporter, Culps said that he had fatally stabbed a man on the Yakama reservation in 2016 to avenge Metsker’s death.

Culps described Metsker in the interview as the mother of his child, according to news reports.

Cloud’s remains were found in Medicine Valley in September and were recently identified through DNA analysis, according to authorities. An autopsy determined he was stabbed to death, Yakima County Coroner Jack Hawkins said.

Thompson was initially charged as an accessory after the fact but was later charged with murder. He is scheduled to be tried in U.S. District Court in February.

Federal prosecutors allege that Neil Cloud and George Skyler Cloud, 22, fatally shot Metsker in late March 2016.

Two women, Nicole Lee Sunny Cloud, 28, and Kristen Ashlie Cloud, 33, were charged with being accessories after the fact, as prosecutors alleged they assisted George and Neil Cloud in avoiding arrest. George, Nicole and Kristen Cloud are scheduled for trial in January.

George Cloud previously pleaded guilty in federal court to an unrelated carjacking case in which federal prosecutors alleged he shot a woman in the leg and stole her car from a Toppenish convenience store parking lot in March 2016.
