An armed robber who later conspired to murder of the his victims was sentenced to 25 years in prison and four years probation on Tuesday.
Deputies say 26-year-old Shaun Tonge robbed an off-duty Phoenix police officer of his handgun and personal vehicle at gunpoint in May 2010.
Three days later, he burglarized a Phoenix home and hit the homeowner in the head with the stolen gun multiple times when she caught him there.
The woman was able to run outside and call 911. Tonge's accomplice, Shanna Lee Parent, also known as Shannon Ladue, was waiting nearby and drove off without him.
Deputies say they found him hiding in an alley a block away.
While in custody waiting to be tried on multiple counts of armed robbery and aggravated assault, Tonge tried to convinced Parent and another man to murder the woman he had robbed and attacked.
Maricopa County Sheriff's office found out about the plot and used an undercover officer posing as a hit man to eventually arrest her in Oct. 2010. Deputies say the woman wasn't harmed.
Parent pled guilty to one count of attempted first degree premeditated Murder and was sentenced to eight years in prison.
Attempted first degree premeditated murder was added to Tonge's charges.
Before opening arguments began in his trial, Tonge asked to change his plea to guilty for his charges.
He was sentenced to 12.5 years on each count to be served one after another.
