TUCSON (KVOA) - The individual arrested in connection to Monday's downtown shooting that left a Drug Enforcement Administration agent dead was identified in court documents obtained by News 4 Tucson on Tuesday.
On Monday, Devonte Okeith Mathis was arrested on drug charges after he and an unidentified individual were allegedly caught in possession of a large amount of marijuana during a routine interdiction on an Amtrak train stopped at the downtown train station, located at 400 N. Toole Ave.
According officials, the unidentified individual and Mathis were reportedly sitting in the back row of the train stationed when a DEA agent observed Mathis reportedly retrieve several bags.
When the agent asked Mathis about the bags, he allegedly denied that the bags belonged to him. However, after he removed the bags from the train, the DEA agent opened one bag and said he found "two packages of bulk marijuana."
Two other DEA special agents, one of which was identified by the Associated Press as Mike Garbo, to speak with the unnamed individual who accompanied Mathis on the train. After consenting to a K-9 sniff of his bags, the unidentified person reentered the train.
After Garbo and the other DEA agent received word about the two packages of marijuana, the two agents approached the unnamed suspect on the train. Upon contact, the unidentified individual reportedly shot and killed Garbo and shot the other DEA agent several times. Officials say a Tucson Police Department officer was also shot and injured in connection to the incident.
