Compassionate. Humble. A good friend. A dedicated public servant.

Those were some of the words that family and friends used during a funeral service Saturday to fondly remember a law enforcement officer who was among three people killed in a shootout near Texas A&M University.

More than 3,000 people attended the service for Brazos County Constable Brian Bachmann at an arena on the A&M campus in College Station. Among those in attendance were law enforcement officers from across the state, including Lubbock in West Texas and Hidalgo County in South Texas. A choir of more than 80 people from Bachmann's Methodist church in College Station sang during the service.

"Brian would sacrifice himself for the benefit of others, always," his mother, Carmen Bachmann, said as she stood on a stage above her son's flag-draped coffin.

Authorities say Bachmann was fatally shot Monday by Thomas Alton Caffall III. The 41-year-old constable was trying to serve Caffall with a court summons for being two months behind on rent. Other officers fatally shot the 35-year-old Caffall.
