I found an article about Troy Driver's 1997 crime, which was indeed a murder, but he wasn't the main killer.
The killer was actually the girlfriend of the victim, who lured him to come take a look under the hood of a car, and then shot him in the head with a shotgun. Driver and another dude helped move and dump the body. All three were involved in the planning stages of this murder, which was premeditated. The shotgun was provided by either Driver or the other guy (it's not clear which one).

The girlfriend, Alissa Marie Moore, then 18, was sentenced to 15-years-to-life for this one. There were fears that Moore would possibly be out by age 32, as she committed the murder at age 17. However, it hasn't happened. She's now 42, and still in the clink.
In 2013, she was denied parole:

She's still in prison:

This actually surprises me, because California parole boards tend to be quite liberal, and she was a 17-year-old female at the time of the murder, which tends to get more leeway in spots like these than dudes in the same spot. Perhaps her behavior behind bars has been bad, or perhaps she isn't showing sufficient responsibility or remorse for what she did.
The worst thing you can do at a parole hearing is take a "it wasn't me" attitude, or state that you were justified to commit the crime.
