Brittany Killgore Murder: Suspects in Marine's wife slaying face preliminary hearing Monday

(CBS/AP) VISTA, Calif. - A preliminary hearing is scheduled this week for three people charged with torturing and killing Brittany Killgore, the wife of a Camp Pendleton Marine.

The hearing is scheduled Monday morning in Vista for Louis Perez, 46, Jessica Lopez, 25, and Dorothy Maraglino, 37. They've pleaded not guilty to murder in the 22-year-old Killgore's April 2012 death.

The hearing is expected to last five days and will determine whether there's enough evidence for them to stand trial.

Prosecutors said Perez kidnapped Killgore after he picked her up for a dinner cruise on April 13, according to the San Diego Reader. He allegedly took her to Maraglino's home in Fallbrook, a short distance from Killgore's apartment, where he summoned Maraglino and Lopez to come over.

Then the three accused persons "acted out parts of fantasies that members of the conspiracy had previously communicated within the BDSM community which included kidnapping a woman off the street, taking the woman somewhere, playing with the woman and raping the woman," Deputy District Attorney Patrick Espinoza says in court documents.

The alleged attack included use of a stun baton and causing "incised wounds" and a ligature on the victim's neck, according to the prosecutor.

Killgore's body was found April 17 in a rural area east of Temecula, a week after she filed for divorce from her husband, a Marine who was fighting in Afghanistan. The husband is not suspected in her death.
