Police say a gunman was being served an eviction notice before he opened fire from inside a home near Texas A&M and killed a law enforcement officer.

College Station Assistant Police Chief Scott McCollum says Brazos County Constable Brian Bachmann was among three people, including the gunman, killed in a shootout at the house Monday.

McCollum says a 65-year-old man was the third person killed. A woman and three law enforcement officers also were injured.

McCollum says Bachmann went to the off-campus home near A&M's football stadium early Monday afternoon when the gunman opened fire. Other officers responded to the scene after receiving a call that an officer was down.

The shooting prompted Texas A&M to send out an alert warning students and residents to stay away from the area.
