Case narrative

Aftermath

In Riverside, Greg was originally charged with two felonies: attempted lewd or lascivious acts with a child under 14 years of age and attempted forcible sexual penetration with a foreign object. His bail was set at $50,000. The District Attorney's office requested that his bail be raised to $1 million because he had two prior felony convictions. Greg was immediately taken into custody once Judge Schwartz gave his approval. In 2009, Greg ended up pleading guilty to the former charge and was sentenced to eight years in prison with credit for three years of time served, and continued lifetime registration as a well above average risk sex offender.

2023 update

Hansen attempted to reach out to Greg for an interview after obtaining a couple of phone numbers belonging to him, but Greg did not respond.

Trivia

Greg is second behind both Michael Seibert and Robert Lyons as having the highest bail of any predator featured in Hansen's predator investigations. Seibert, after being arrested in the Long Beach sting, had his set at $1.1 million due to his prior involvement in the Riverside sting. Lyons, who had previously been convicted for having sex with an underage male prostitute, also had his bail set at $1.1 million.
