TUCSON, Ariz. — Two people are dead after a shooting on board an Amtrak train in Arizona.

On Monday, agents from the Drug Enforcement Administration and Tucson, Ariz., Police Department were doing a regular sweep of the eastbound Sunset Limited for illegal drugs and weapons during a station stop when one person onboard opened fire on the officers. One DEA agent was killed and two other law enforcement officers were injured. The shooter barricaded himself in a bathroom and was eventually killed, although it’s unclear if they were shot by officers or if they took their own life, the New York Times reports. 

One other person was arrested at the scene. All other passengers were safely evacuated from the train.
