A passenger had bulk marijuana on a train before fatally shooting drug enforcement agents in Tucson, Ariz. on Monday, investigators said.
A federal criminal complaint filed in a U.S. District Court on Tuesday alleged the Amtrak passenger had five pounds of “bulk marijuana” and 50 packages of edibles, according to The New York Times.
The complaint did not identify the gunman by name but provided new details about the sequence of events that led up to the shooting.
As drug enforcement officers boarded, the passenger stowed the products elsewhere on the train and returned to his seat, the Times reported.
The gunman was seated across from Devonte Okeith Mathis, who was later charged with intent to distribute marijuana, according to the Times.
The complaint said that Mathis denied that a bag containing marijuana belonged to him. After that interaction, the agents approached the gunman who opened fire on them.
The shooting left one DEA agent dead, another agent critically injured and a police officer hospitalized.
The agents were aboard the train investigating a tip they received from Amtrak. All 137 passengers and 11 crew members aboard the train were safely evacuated, an Amtrak representative told the Times.
Arizona allows people who are over 21 to have one ounce of marijuana for recreational use. However, possession of marijuana remains illegal at the federal level. Trafficking the drug is illegal at both the state and federal level.
