A mass shooting Thursday at Fort Hood in Texas was the latest in a series of violence incidents at the military post in the past two years.
In September 2008, a 21-year-old Fort Hood soldier shot to death his lieutenant during a confrontation at his off-base apartment before turning the gun on himself.
The lieutenant and a staff sergeant went to the Army specialist's apartment, and a confrontation ensued. Killeen police officers responded to a call of a man with a gun, and they saw the specialist hit and then shoot the lieutenant as they arrived at the scene, Killeen police spokesman Carroll Smith said.
Two months later a New York parolee with an extensive criminal record was executed for robbing, raping and fatally shooting an Army medic at her apartment near Fort Hood.
Denard Manns, 42, who came to Texas after a second prison sentence in New York for armed robbery, was condemned for the murder 10 years ago of Michelle Robson, 26.
In July of 2009, Fort Hood Spc. Armano Baca was charged with murdering fellow soldier Spc. Ryan Richard Schlack from Wisconsin.
Baca and Schlack were members of the 1st Calvary Division and had recently returned from tours in Iraq.
Schlack was shot during a party at the Central Texas Army post and died at a Fort Hood hospital July 18.
Three months ago Spc. Jared Lee Bottorff was charged with murder after a shooting at a party near the post.
At the time, police said Bottorff and another soldier was at a party at house when a fight broke out and someone was shot and killed.
Bottorff was jailed on $1 million bond.
