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

The violence Monday left a neighborhood shaken, a law enforcement community in mourning and the family of 35-year-old gunman Thomas Alton Caffall "distraught by the havoc that he has caused."

Officers responding to the scene exchanged shots with Caffall, 35, for nearly 30 minutes.

By then, Caffall and Brazos County Constable Brian Bachmann had been mortally wounded. So was 43-year-old Chris Northcliff, of College Station, who was apparently caught up in the gunfire.

Police wouldn't speculate on what sparked the deadly outburst, which is the latest shooting nationwide resulting in multiple deaths in recent weeks.

KHOU in Houston received cell phone video of the shooting exchange between officers and Caffall. You can see it below.
