Have you seen Benjamin Song? State and federal agencies have issued a Blue Alert for a suspect who allegedly shot a Texas police officer during the attack of a U.S. Immigration and Customs Enforcement (ICE) detention facility on July 4.

Song, a former Marine Corps reservist, has been charged by federal complaint with three counts of attempted murder of federal agents and three counts of discharging a firearm in relation to a crime of violence, according to a statement. Song allegedly purchased three of the firearms used in the crime.

Phones buzzed across Texas just before 8 p.m. Wednesday with a high-priority emergency alert. But it wasn't about flooding, a storm, or a missing child. It was about a five-day-old shooting at an ICE detention center hundreds of miles away.
