COLLEGE STATION, Texas (CNN) -- A Texas constable and two others were killed Monday in a shooting near Texas A&M University, police said.
Scott McCollum, assistant chief with the College Station police department, told reporters Monday afternoon that the three people killed were the constable, the man authorities say exchanged gunfire with law enforcement officers and an unidentified 65-year-old male civilian.
The dead included Brian Bachmann, a constable in Brazos County, according to McCollum. According to his Facebook campaign page, Bachmann was a 41-year-old from College Station who had been a Brazos County sheriff's deputy since 1993. The county's website indicated that his four-year term as constable was set to expire on December 31, 2014.
"He was a pillar in this community, and it's sad and tragic that we've lost him today," McCollum said.
The assistant police chief didn't offer details on the suspected gunman, beyond saying he was in his mid-30s. As to the third victim, a post on the city of College Station's official Twitter page identified him as a "civilian bystander."
Four others suffered injuries in the prolonged ordeal, which occurred a few blocks from the Texas A&M campus.
They include a law enforcement officer who was shot in the calf and two other officers who suffered "non-life threatening injuries," McCollum said. A 55-year-old female civilian was also shot and was undergoing surgery Monday afternoon at a hospital, according to the assistant police chief.
He explained that police got a call shortly after 12:10 p.m. from "a citizen" indicating shots had been fired in the residential area just south of the university campus. He added that the constable had gone to the residence to deliver an "eviction notice."
Texas A&M issued a Code Maroon -- the university's emergency notification system -- at 12:29 p.m., telling people to avoid the area where there was a report of an "active shooter."
By then, two law enforcement officers who were nearby had responded and found the constable down in the front yard of a home. They "received fire from the suspect inside, ... took cover and defended themselves," McCollum said, noting other officers were then called to the scene.
"They ended up shooting the gunman," said the assistant police chief.
At 12:44 p.m., Texas A&M posted another Code Maroon update on its website indicating the suspect was by then "in custody."
Officer Jon Agnew with the Bryan Police Department -- a community that's adjacent to College Station -- noted the shooting occurred in a "residential area." He and McCollum said authorities were investigating, and they stressed that authorities had control of the scene.
"The area is secure," Agnew said. "We feel the community is safe for right now."
