Two men already jailed on federal drug and weapons offenses are being charged with the murder of a 35-year-old Anchorage man who was working as an undercover informant for the Anchorage Police Department.

Marquis Eloi, 38, and Scotty Mataia, 30, face first-degree murder charges in the death of David Cargill, police said in an alert Tuesday. Cargill’s body was found near the old hydroelectric plant along the Old Glenn Highway last month. Investigators said he suffered multiple gunshot wounds.

Federal investigators have already detailed much of what authorities believe happened to Cargill, who allegedly made several drug buys and purchased a stolen firearm while secretly working with police in the months leading to his death. According to an affidavit filed by Bureau of Alcohol, Tobacco and Firearms special agent J. R. Crump, Cargill was killed after Eloi and Mataia learned Cargill was working with APD.

In September, the auto body shop where the purchases allegedly occurred was raided by police. Eloi and Mataia were later arrested, and through the discovery process, Eloi’s attorney was given information about the department’s use of a confidential informant.

Cargill stopped by the business Oct. 14, Crump wrote. After a conversation with Mataia, Cargill was seen going into a rear area of the shop.

“A short time later, a scream was heard followed by the sound of a single gunshot,” Crump wrote.

Police were alerted that Cargill was missing two days later, Crump wrote. The missing man’s body was found the next day in a wooded area near the power plant, and police said there was evidence linking the body to the shop on East 66th Avenue.

When Mataia was shown a photo of Cargill, he allegedly told investigators that Cargill was the person “who told on us.”

APD has not publicly acknowledged Cargill was an informant. On Tuesday, an APD spokeswoman said the department had no further comment on the case.

“This is an on-going investigation that still has to make its way through the court system,” wrote APD spokeswoman Renee Oistad. “Because of this, APD will not be releasing any more information prior to adjudication.”
