LAS VEGAS -- The gunman who killed a security officer and wounded a deputy U.S. marshal had a long criminal record that included murder and sexual assault.

Sixty-six-year-old Johnny Wicks was shot to death by federal agents after he walked into the Lloyd George Federal Courthouse on Monday and opened fire with a Mossberg shotgun. Police say he fired five rounds before fleeing the scene. Court security officer 72-year-old Stanley Cooper was killed and a federal marshal was injured. Several officers pursued Wicks, ultimately shooting and killing him. More than 80 shots were fired during the incident.

SLIDESHOW: Federal Agent Shooting

Wicks was convicted of murdering his brother in Memphis, Tennessee in the mid-1970's. He also faced sexual assault charges in Sacramento, California in the late 1980's.

Records also show that Wicks was disgruntled with the federal government. According to court documents, he filed a lawsuit against the Social Security Administration in April of 2008 alleging racial discrimination. In the handwritten complaint, Wicks said the discrimination had followed him from California to Nevada. Wicks wrote that one California agent, "Doesn't try to hide the way he feels about black people so he reduced my benefits."

Read the Lawsuit filed by Johnny Wicks

Wicks explained he suffered a stroke some years back. He claimed his benefits dropped from $886 to $445 a month and then to $128 a month.

U.S. Magistrate Judge George Foley reviewed the case and determined Wicks' payments were reduced because Nevada, unlike California, does not provide a state supplement. When Wicks moved to Nevada he was no longer eligible for the supplement.

The case was ultimately dismissed in September of 2009.

According to police, Wicks has a lengthy criminal history, including an arrest for murder and domestic violence.

Prior to Wicks' arrival at the courthouse, investigators say he set his home on fire. He lived at Sunrise Senior Village on 30th Street in Las Vegas.
