A law enforcement officer among three people killed in a shootout near Texas A&M University is being remembered as a good friend, a loving family man and a dedicated public servant whose calling in life was to help others.

Several thousand people attended a funeral service for Brazos County Constable Brian Bachmann on Saturday in College Station.

Friends and family described Bachmann as compassionate, humble and selfless.

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 behind on rent.

Other officers fatally shot Caffall. His family members have said he suffered from an unspecified mental illness.

A bystander checking some property was also killed. Three police officers and a female bystander were wounded.
