SALT LAKE CITY (ABC4) -- The Utah Department of Homeland Security was at the center of an FBI raid within the last week, resulting in at least one agent in custody.

That agent has now been identified by court documents as David Cole. He has been federally charged with one count of conspiracy to distribute and possess with intent to distribute a controlled substance.

Prosecutors say Cole, along with an unidentified agent, used his position with Homeland Security Investigations to sell cathinone, or bath salts, using an HSI-sanctioned informant. According to court documents, the informant would purchase the bath salts from the two agents before selling them on the streets.

Cole and the unidentified agent allegedly never arrested any of the people the informant would sell the bath salts to. Meanwhile, the informant continued to perform legitimate controlled buys with other HSI agents.

In October 2024, the informant reportedly told his attorney that Cole and the unidentified agent were asking him to do unlawful acts outside of HSI-sanctioned operations.

The FBI launched an investigation, using the informant to gather evidence. Throughout November, the informant wore a wire for the FBI, gathering evidence through several meetings with Cole and the unidentified agent.

"Person A and Cole have conspired and worked together to execute this scheme, regardless of which one of them actually appears at the buy location to meet [the informant]," court documents state.

According to the FBI investigation, Cole and the unidentified agent profited between $150,000 and $300,000 in illegal proceeds earned through the sale of bath salts.

The investigation culminated in a raid late on Wednesday, Dec. 4, and Thursday, Dec. 5. FBI agents searched the two agents' cubicles, vehicles, phones, and homes, seizing bath salts and $67,000 in cash, among other evidence.
