PHOENIX — A co-conspirator of the man who killed a federal agent on an Amtrak train in Tucson in 2021 pleaded guilty on Wednesday to multiple drug and weapons charges, federal prosecutors said.

Devonte Okeith Mathis, 24, pleaded guilty to conspiracy to possess with intent to distribute marijuana, using and carrying a firearm during and in relation to a drug trafficking crime and possession of a firearm in furtherance of a drug trafficking crime, the United States Attorney’s Office for the District of Arizona said in a press release Thursday.

A conviction on the drug trafficking charge carries up to five years behind bars, a fine up to $250,000, or both, while a conviction for the weapons-related charges has a mandatory minimum sentence of five years in prison to run consecutively with other counts, a fine of up to $250,000, or both.

Sentencing for Mathis, of Mesquite, Texas, is scheduled for May 24.

Drug Enforcement Administration agents and police officers were inspecting baggage belonging to Mathis and Darrion Taylor for contraband on tips from Amtrak at the train station in downtown Tucson on Oct. 4, 2021.

After finding two bulk packages of marijuana, DEA agents reentered a train car to talk to Taylor.

Taylor proceeded to open fire, killing DEA group supervisor Michael Garbo and injuring a second DEA agent and a DEA task force officer.

Taylor was found dead after barricading himself in a bathroom and exchanging gunfire with several responding officers.

Mathis, in pleading guilty to the charges, admitted to knowing Taylor had two handguns and he could use the weapons for the drug trafficking conspiracy, authorities said.

“Yesterday [Wednesday] was an important step in securing justice on behalf of a federal law enforcement agent,” United States Attorney Gary Restaino said in the release.

“We await the sentencing in this matter. In the meantime, we celebrate Michael Garbo’s life of service, we mourn with his family and his colleagues at the Drug Enforcement Administration and we remember his end of watch on October 4, 2021.”
