Bennett was last seen in Los Angeles, California on February 16, 1983. He was was employed as a supervisor at the Whittier Narrows Sanitation Plant at the time of his disappearance. He has never been heard from again. Large amounts of his blood was later found in an overgrown area behind the sanitation plant and in a dump truck. Tire tracks from Bennett's truck and the dump truck were also found.

In 2006, John Alcantara was charged with murdering Bennett. A photograph of Alcantara is posted below this case summary. He has a criminal record with convictions for theft, cocaine possession and vandalism. He had worked as a gardener under Bennett at the sanitation plant in 1983. Alcantara had wanted a promotion to foreman, which was denied because Bennett gave him a poor performance review. He allegedly exhibited bizarre behavior at work, including exposing himself and masturbating in front of coworkers. The day before Bennett disappeared, the two men argued and on February 16, a coworker told Bennett that Alcantara had threatened him. Bennett was last seen when he drove his truck to where Alcantara was and told him to get inside.

Authorities believe Alcantara shot Bennett in the head and dismembered his remains. Supposedly, another coworker, who is now deceased, disposed of the body in the Puente Hills landfill. Alcantara had been a suspect in the case since shortly after Bennett disappeared, but prosecutors lacked the evidence to charge him until a witness came forward in 2004. The witness stated Alcantara had confessed Bennett's murder to him. Alcantara maintained his innocence is Bennett's case, but was convicted of murder in March 2008. He faces 25 years to life in prison.

In spite of an extensive search of the landfill, Bennett's remains have never been located. Foul play is suspected in his case due to the circumstances involved.
