The system failed - this guy was a thug criminal, history and life of violence .............. we HAVE to get better background checking and when they fail, prosecute them fully. As it is, they don't :(
Gary Martin, 45, had at least six prior arrests and used an illegal firearm, police said.
The gunman who opened fire in an Aurora factory, killing five and wounding six, was a divorced father of at least two children with a history of violent and threatening behavior spanning more than two decades, according to court records.
“I felt helpless,” an ex-girlfriend wrote in a 2008 petition seeking a restraining order against Gary Martin. “Confused and scared. I have no one to defend me. Not even the law.”
Martin had threatened to kill her, had put his hands on her and beat her, and had thrown rocks at her, bruising her leg, she stated in the petition.
It was around the time that he and his wife had stopped living together. In 2011, she filed for divorce and sought custody of their two children, now 9 and 14.
“Without cause or provocation (Martin) has been guilty of extreme and repeated mental cruelty toward the petitioner,” Martin’s ex-wife stated in her petition for dissolution of marriage.
Martin’s history of violence dates back to at least 1995, when he was convicted of aggravated assault in Mississippi, authorities said.
About 13 years later — between July 16 and August 25, 2008 — a woman documented at least seven instances when his behavior made her afraid. They lived in different building in the same apartment complex and had dated less than a year, according to court records.
