A homicide victim, now identified as a confidential informant for the Anchorage Police VICE Unit, was killed just days after evidence of undercover drug buys was turned over to a suspect's defense attorney. His mother says he was never warned his identity had been compromised. 

On Oct. 19, APD announced the discovery of a body on Oct. 17 in the area of the Eklutna Power Plant. The victim was later identified by APD as 35-year-old David Cargill, who died of multiple gunshot wounds to the upper body. 

Little information was made public about the circumstances surrounding Cargill's death until federal charges were filed in a connected case Friday.

A complaint document signed by ATF Special Agent J.R. Crump lays out a months-long drug investigation by APD's VICE Unit that resulted in federal drug and weapons charges for 38-year-old Marquis Eloi and 30-year-old Scotty Mataia.

It also provides enough information to identify an APD confidential informant as recent homicide victim David Cargill, Debbie Cargill's son. 

"He was no angel," she admits. "I mean, I'm not gonna say he didn't have his faults. He did have faults, but he had many good things in him and I'm hoping people remember him for trying to clean up the world by what he was doing." 

According to the federal complaint, David completed five undercover buys for APD at a local auto body shop during the months of June, July and August, often recording video and audio the exchanges. He purchased methamphetamine, cocaine, opioids and a loaded, stolen gun. 

 

In a Sept. 6 raid, APD executed a search warrant at the business on East 66th Avenue and seized 22 firearms, more than $70,000 in cash, an apparent "drug ledger" and scales and packaging materials. 

They also arrested Eloi on nine felony drug and weapons charges. According to the document, he was experiencing health issues and was taken to a local hospital. Once discharged on Sept. 13, he was booked into jail. He posted bail and was released the same day. 

 

On Oct. 11, Eloi's defense attorney received discovery materials in the state case against him, including the recordings made by David. 

By Oct. 16, Debbie reported her son missing, telling authorities he was last seen on Oct. 14.  

David's body was found on Oct. 17 with gunshot wounds in the torso.  

According to the charging document, materials found at the site of the body matched items seen at the business on 66th Avenue, including FastLine brand commercial grade automotive masking film and blue painter's tap.

Additionally, APD interviewed witnesses who reported seeing David go behind the business with Eloi and Mataia on Oct. 14, then heard a scream and a single gunshot. 

 

During a second search of the business on Oct. 19, the document says when APD showed Mataia a photo of APD's "Confidential Informant 18-3," Mataia said the person in the photo was the person "who told on us."  

"I'm proud of him for what he did, but I don't like the way it ended," said Debbie. 

She said she was aware that David was working as a confidential informant for APD and worried "all the time." 

Once Eloi was able to pay his $15,000 bail and get out of jail; Debbie said she worried even more. 

"I knew there was gonna be problems, or I felt there was gonna be problems," she said. 

Debbie said David was motivated to be a confidential informant because he wanted to set a better example for his teenage sons. 

"He had used drugs in the past... He thought the only way for him to really get off the stuff was to try and help the police department get rid of the drug dealers in town so he could get clean and wouldn't be able to go to the places he was going to to get drugs," she explained. 

KTVA previously reported Cargill was charged in a 2015 sex abuse and drug case. The charges no longer appear in online court records. 

His mother said the charges were unfounded and later dropped, and did not serve as incentive for his cooperation with APD.  

Multiple inquiries to confirm the resolution of the charges have gone unanswered.   

Debbie said better protections for confidential informants are necessary. 

"Otherwise, I think they're not going to be able to get confidential informants. David thought he was safe. He didn't think that any of the information would get out unless it went to trial or whatever, but apparently, all the information got out about who was doing what, and that's what ended his life," said Debbie. 

When asked if David was ever warned his identity had been compromised, she responded, "Not that I know of. I don't want to condemn anybody or anything, but as far as I know, no." 

APD Communications Director MJ Thim responded to several questions Tuesday with this statement: 

"We don't discuss confidential informants due to the sensitivity and safety of those investigations. Detectives continue to investigate why the victim was killed and who's responsible." 

The Office of Special Prosecutions, which is prosecuting Eloi on the state charges, declined an interview Tuesday, as did the prosecutor in the U.S. Attorney's Office pursuing the federal charges against Eloi and Mataia. 

Michael Moberly, listed in online court records as Eloi's defense attorney in the state case, did not respond to a voicemail. 

A GoFundMe page has been started for Debbie who is now without a vehicle and planning her son's funeral. 

She joins APD in asking that anyone with information about David's death come forward. Information can be reported anonymously through Crime Stoppers: 907-561-7867.
