(CBS/AP) COLLEGE STATION, Texas - A deadly shootout erupted Monday near the Texas A&M University campus when a man being brought an eviction notice opened fire on a Texas law enforcement officer, leaving three people dead, including the officer and the gunman.
Police say Thomas Alton Caffall, 35, opened fire on Brazos County Constable Brian Bachmann just after noon as the lawman brought an eviction notice. Both men were later pronounced dead at a hospital.
Police identified Chris Northcliff, 43, as the third person killed in the shootings at an off-campus home not far from the university's football stadium. Three other law enforcement officers and a 55-year-old woman were wounded, College Station Assistant Police Chief Scott McCollum said.
Caffall's sister said Monday night the family was "shocked" by the violence.
"Our hearts and prayers go out to the families and this is just a senseless tragedy," said Courtney Clark, Caffall's sister, reached Monday evening at her mother's home in Navasota, about 20 miles to the south. "We are just distraught by the havoc that he has caused."
She declined additional comment.
Caffall's stepfather, Richard Weaver, told CBS station KHOU that the suspected gunman refused to work after apparently quitting his job less than a year ago. Weaver said Caffall regularly played video games inside his rental home near the campus. According to KHOU, Northcliff, the third man killed on Monday, was Caffall's landlord.
Weaver told KHOU that Caffall played video games so much that it seemed to be warping his sense of reality. He said Callfall's alleged violent reaction to an eviction notice was not something that surprised him. Weaver even told KHOU he had become concerned that Callfall might hurt, or even kill, one of his own family members in recent months.
Weaver told KHOU reporter Drew Karedes over the telephone that he was worried his stepson was going to snap. When asked if the family ever brought the concerns to authorities, he said they had not.
Officers responding Monday afternoon to reports of an officer down saw Bachmann wounded on the ground in the front yard, then got into what McCollum described as an extended shootout with Caffall, who eventually was shot.
Police spokeswoman Rhonda Seaton said Northcliff was outside the home when he was shot, as was the wounded woman, whose name had not been released by Monday evening.
The woman was hospitalized in serious condition following surgery. One of the injured officers, Justin Oehlkee, was treated for a gunshot wound in the calf and was in stable condition, Seaton said. Two other officers - Brad Smith and Phil Dorsett, were treated for "shrapnel injuries" and released, Seaton said.
Police declined to speculate on a motive for the gunfire.
The shootings prompted Texas A&M to issue an emergency alert warning students and residents to stay away from the area. Most of the university's 50,000 students were not on the campus about 90 miles northwest of Houston because the fall semester doesn't start until Aug. 27, university spokeswoman Sherylon Carroll said.
Diana Harbourt, 27, who lives about a block from where the shootings happened, said she heard five loud popping sounds from a back room of her home looking out her front door to see an officer park his vehicle on the street and crouch in front of another vehicle.
"We heard him exchanging some words with the person and then shots being fired," Harbourt said. "And then we heard more sirens and more officers and fire trucks came and they were keeping their distance, kind of slowly moving in. More officers showed up and told us to stay inside."
Officers, meanwhile, were dealing with losing someone McCollum called a respected colleague.
"Brian Bachmann was very close to everyone in law enforcement," McCollum said. "He was a pillar in this community, and it's sad and tragic that we've lost him today."
Bachmann, 41, worked more than 19 years in law enforcement, according to the Texas Commission on Law Enforcement Officer Standards and Education. He started out with the Hempstead Police Department before spending most of his career with the Brazos County Sheriff's Office. He had been a constable since January 2011, after winning election to the post the prior November.
In a February 2010 candidate profile in the Bryan-College Station Eagle, the married father of two said he wanted to bring "constables back to the community" by actively patrolling neighborhoods to discourage crime.
Constables are law enforcement officers similar to sheriff's deputies who are elected to serve in specific county precincts. They primarily serve warrants and official paperwork or act as courtroom bailiffs.
Texas Gov. Rick Perry, an A&M alumnus, said at an event in Florida that his "prayers are with any of those that have been injured." A&M President R. Bowen Loftin issued a statement calling Monday a "sad day in the Bryan-College Station community."
