According to College Station police, there were multiple crime scenes at which five people were shot.
Constable Brian Bachmann, as well as an unidentified civilian male and the shooting suspect, were killed. A College Station police officer was shot in the leg, and a female civilian was shot and injured. The officer is listed as stable. The female victim was taken into surgery at A&M St. Joseph Hospital.
Constable Bachmann was serving an eviction notice at a residence in the 200 block of Fidelity when he came under fire from the suspect, said College Station Police Department Assistant Chief Scott McCollum.
Two other officers were close by and responded, McCollum said. As they approached the scene, the suspected reportedly began to open fire on them, too. They took cover and defended themselves.
Soon, more officers arrived at the scene. Two of them opened fire on the suspect and fatally shot him. Constable Bachmann was then transported to a hospital, where he was pronounced dead.
"Brian Bachmann is very close to everyone in law enforcement. He was a pillar in this community and it's sad and tragic that we've lost him today," McCollum said. "And as you can imagine, as close as he was to all the officers in this area, these are the officers that are having to work this case and work through not only the emotions but all the details that required to make sure that we have a good understanding as to why this occurred."
The suspect is said to be in his mid-30s. The male civilian who was also fatally shot is said to be 65 years old and the woman who was injured during the shooting is 55. None of their names have been released.
Authorities are still trying to determine the motive behind the shooting.
"We still have a lot of questions to ask and we just ask that the public be patient with us as we wade through this volume of information and as best as we can, try to make some sense out of this situation," McCollum said.
The scene is a few blocks from the campus football stadium, Kyle Field, and prompted Texas A&M officials to take action. At about 12:30pm, a Code Maroon warning was issued to students to avoid the intersection of Welborn Road and George Bush Drive.
Bryan Police spokesman Jon Agnew says police don't know if the shooter was a student at A&M.
Texas A&M spokeswoman Sherylon Carroll could not confirm any injuries or details about the shooting, but said most students were not on campus Monday and the fall semester doesn't begin until August 27.
"It appeared to be fairly quiet," Carroll said of campus. "It didn't appear to be a lot of people out and about at that particular time."
College Station police are still advising residents and students to avoid the area.
Constable Bachmann has been a certified peace office since 1992. He's became a Brazos County sheriff's deputy in 1993.
Meanwhile, the community is already coming together. Christ United Methodist Church on Highway 6 in College Station and A&M United Methodist Church on University Drive in the Northgate area will both hold vigils at their facilities at 7pm.
