The FBI and Texas DPS are asking for the public's help in the search for Benjamin Song, accused of shooting an officer in the Alvarado ICE attack.

He is wanted in connection with a July 4 attack on the U.S. Immigration and Customs Enforcement (ICE) Detention Facility in Alvarado, Texas, where an Alvarado police officer was shot.

The suspect is believed to have fired two AR-15-style rifles at three officers, and his criminal complaint document says he was in the U.S. Marine Corps Reserves for five years.
