Scott Allen Ostrem, the man accused of shooting and killing three people at a Walmart in suburban Denver Wednesday evening, usually kept to himself and was sometimes seen carrying a rifle bag back and forth between his apartment and car, neighbors said Thursday.

Colorado court records show he has been arrested at least four times since 1990, when he was arrested on a harassment charge in Westminster. He was found guilty of the charge and sentenced to two days in jail.
In April 1991, Ostrem was charged with driving under the influence in Adams County, but he was never convicted, according to the court records.
In December 1999, he was charged in Denver with assault on a peace officer, possession of dangerous weapons, disorderly conduct and resisting arrest.

In January 2013, Ostrem was arrested by Wheat Ridge police on a DUI charge. But the charge was eventually lowered to driving while ability impaired...
He declared Chapter 7 bankruptcy in September 2015...
...he walked off the job Wednesday morning before the shooting, employees confirmed.
At the time of the bankruptcy filing, he calculated he was expending about $270 a month more than he was receiving in income. The filing also showed that there were dozens of creditors seeking payments from Ostrem, including the IRS and Colorado Department of Revenue.
His bankruptcy attorney told Denver7 he didn’t remember much about Ostrem, but said the shooting was “very sad.”
Records from the Colorado Secretary of State's Office show that Ostrem also created two different limited-liability corporations in Colorado that have both since been classified as delinquent.
He registered Ostrem Installation LLC in June 2012 at an address in Thornton. It was delinquent as of No. 1, 2013.
And he registered MKA Electronics LLC on Jan. 2, 2013 at a PO Box in Arvada, which was delinquent as of June 1, 2014.
Ostrem is registered as a Republican in Colorado, according to voter records. He is not married.
