PHOENIX - Police have confirmed that a man, who was already in jail for an unrelated incident, is accused of burying two people in a Phoenix backyard in 2011.
According to Phoenix police Sgt. Tommy Thompson, 42-year-old Alan Matthew Champagne is accused of killing a man and woman, who he got into an altercation with in October 2011.
Detectives identified Champagne as a probable suspect, but the bodies were not found.
In March 2012, he ended up in a barricade situation at his mother's home near Indian School Road and 16th Street.
He was arrested and charged with multiple counts of attempted first degree murder for trying to shoot police officers, Thompson said.
While in jail, detectives continued investigating the double homicide and discovered more evidence that pointed to Champagne as the suspect, Thompson said.
His mother has since moved out of the home near Indian School Road and 16th Street.
On Tuesday around 1:45 p.m., Phoenix police were called to his mother's former house.
The current owners hired landscapers to renovate the property, who then found a wooden box buried in the yard.
In the box were the remains of what looks like a male and female victim, Thompson said.
The remains were taken to the Maricopa County Medical Examiner's Office, where autopsies will be conducted.
On Wednesday, Champagne was transported to Phoenix Police Headquarters to be interviewed about the double homicide.
He chose not to speak to detectives, Thompson said. But there was reportedly probable cause to charge him with two counts of first degree murder.
