On April 10, 2016, Alameda County Sheriff’s deputies responded to a music studio on Lake Chabot Road in Castro Valley after a reported shooting. When deputies arrived, they found Martinez lying on the ground of the parking lot, suffering from a single gunshot wound to the side of his head. He was pronounced dead at the hospital.

The four-unit office complex houses three medical offices and the hip-hop production studio Trak Nation, which has provided production for Bay Area rappers such as Dru Down and Keak da Sneak. According to Martinez’s Facebook page, he was an “audio finesser” for Trak Nation.

A witness to the shooting testified that an unknown gunman approached Martinez, ordered him face down on the ground and shot him before fleeing the scene.

Alameda County Sheriff’s detectives discovered that Jones had taken out multiple life insurance policies in Martinez’s name over the five months prior to the shooting. A search of Jones’ home revealed five different policies totaling $1.35 million as well as prepaid credit cards in the victim’s name.

Almost a year after the murder, the defendant admitted during an interview with detectives that he had opened the insurance policies, secretly installed a GPS tracking device on the victim’s car and paid a man an undisclosed amount of money to shoot the victim. He also admitted to his unsuccessful attempts to try to collect the insurance money.

Jones told detectives that the two had been friends, but Jones wanted revenge after they had a falling out over a rent dispute. After the interview, detectives found the GPS tracking unit from underneath the victim’s car. When Martinez was fatally shot, he was inches away from his car and the tracking unit.
