Champagne's legal troubles started when he was 15 years old. According to court documents, he began sniffing paint during his early teens.
Champagne was also convicted for second degree murder in 1992. The 42-year-old was also accused of being a member of the Thirteenth Street East Side Loco Gang in the 1990s.
According to court records, Champagne was convicted of stabbing Ricky Marquez to death during a fight at a party. Court documents indicate he may have done so "because of his extreme intoxication induced by his consumption of alcohol and drugs."
He served 13 years in prison and was released in 2005.
Court records show Champagne had an arrest warrant for aggravated assault and trespassing charges. When police tried to contact him, he fired more than two dozen rounds at them with an AR15.
Champagne "admitted to holding his son and girlfriend as hostages and that it was against their wills."
He told the negotiator "that he would shoot any officer that came into his house and that he was not going to surrender…(Champagne) told the investigator he would rather die a free man than die a caged animal," records show.
Champagne was indicted on 52 criminal counts, including attempt to commit first degree murder, misconduct involving weapons, aggravated assault, and kidnapping.
His trial is set to begin April 18.
Police on Thursday confirmed Champagne is now considered a suspect in a double homicide following the discovery of human remains in a Phoenix backyard.
