Three people were killed -- including a law enforcement officer -- and three others were injured after a gunman opened fire near the Texas A&M campus on Monday, police said.
The suspected gunman was among the dead, shot after trading gunfire with police, said authorities in College Station, Texas.
Details surrounding the incident were scarce as College Station police try to piece together a chaotic scene that began unfolding shortly after noon, local time.
Authorities have identified that slain lawman as Brazos County constable Brian Bachmann, 41. Additional identities were not immediately made available.
Scott McCollum, assistant police chief in College Station, said during a media briefing that it was not immediately known why Bachmann, an elected official, was at the scene of the shooting.
"It is a tragedy," McCollum said during the press briefing. "We will do our best to conduct a very thorough and accurate investigation to determine why this occurred."
Another press briefing is expected Monday afternoon.
But here's what is known so far:
Police responded to a report of a man with a gun just a few blocks from the college campus.
When police arrived, McCollum said, the gunman opened fire on the officers, who fired back, striking the gunman. A motive is not known at this time, McCollum said. Authorities were still trying to determine the relationship of the civilians to the crime scene.
"We don't believe there is a second suspect," said officer Jon Agnew, a spokesman for police in neighboring Bryan, Texas, assisting with the situation.
Agnew said he could not confirm several media reports suggesting that Bachmann was at the address to serve an eviction notice. But Agnew said that is the type of document work typically handled by constables in Texas.
"I can't confirm that, but that sounds appropriate, about what he was doing [there]," Agnew said.
A third person, a male civilian, was also killed, Agnew said. In addition, a female civilian was shot and injured, and two additional officers were also injured with non-life threatening injuries, Agnew said.
The incident led Texas A&M university to issue a Code Maroon warning on its website just before 12:30 p.m. Monday stating that an "active shooter" was in the area and warning students and others to stay away.
A school representative told The Times the gunman was not on campus.
