Gerald and Charlene Gallego

Gerald Armond Gallego (July 17, 1946 – July 18, 2002) and Charlene Adell Gallego (née Williams; born October 19, 1956), also known as Stephen and Charlene Feil and nicknamed the Sex Slave Killers, were American serial killers who abducted, raped, tortured, and murdered at least ten people between 1978 and 1980.

The couple abducted their victims from areas near the Interstate 80 freeway running through California and Nevada with the sole exception of a victim killed in Oregon. Typically, Charlene lured victims to the couple's vehicle with an offer of selling drugs, invitations to a party, or a request for help distributing flyers. Gerald would then restrain, abduct, and rape them before killing them with a variety of methods, most commonly by shooting. They were nicknamed the "Sex Slave Killers" because of the prolonged torture the victims suffered, which prosecutors asserted was due to the couple scouting for an ideal sex slave.

Charlene accepted a plea bargain whereby she agreed to testify against Gerald and was sentenced to sixteen years and eight months imprisonment in Nevada in February 1983. Gerald was convicted of four murders — two in California and two in Nevada — and received death sentences in both states. His death sentence in Nevada was overturned in 1997 after an appeal but was reimposed two years later. He died of cancer while on death row in Nevada in 2002.

Charlene was released from prison in 1997 upon the conclusion of her sentence and moved back to California, where she maintains a low profile. She continues to deny culpability in the murders and claims she only participated in them out of fear.
