The 38-year-old Martinez was credited 3.7 years for time served, dropping his sentence to just below 50 years.

On Oct. 6, 2021, Martinez pleaded guilty to second-degree murder and trafficking stolen property.

Belman, who owned Arizona Auto Refrigeration, was found dead in his Foothills home in April 2018.

Authorities said Belman had been tied to a chair with belts and neckties. The home was ransacked and several items including a truck, TV, stereo, computer and surveillance cameras were missing.

During Monday’s sentencing hearing, the judge said Martinez planned to steal a Lotus sports car from Belman and had even texted his girlfriend bragging that he was about to get a car.

The Pima County Sheriff’s Department went to Belman’s home when his employees called and requested a welfare check.

According to the Arizona Department of Corrections, Martinez has an extensive criminal history that includes convictions for vehicle theft, aggravated assault, weapons misconduct, forgery and promoting prison contraband.
