Trio pleads not guilty to 2 Calif. murders, one in San Francisco park

SAN RAFAEL, Calif. -- Two men and a woman pleaded not guilty Thursday morning to killing a California therapist on a Marin County hiking trial and a Canadian tourist in San Francisco's Golden Gate Park last month, reports CBS San Francisco.

Steven Carter, 67, was found dead on Oct. 5, and Audrey Carey, 23, of Quebec, Canada was found three days before. Morrison Haze Lampley, 23, Sean Michael Angold, 24, both of San Francisco, and Lila Scott Alligood, 18, of San Rafael, Calif. are charged with murder with special circumstances of lying in wait, multiple murder and murder during commission of a robbery.

They face life in prison without parole or the death penalty if convicted.

The defendants allegedly were armed during the murders but Lampley has been accused in court documents as the shooter.

Lampley also is also accused of shooting Carter's dog, who was still leashed to Carter when he was slain. He also is charged with animal cruelty.

Police say the defendants stole Carter's Volkswagen Jetta and Carey's camping equipment, including a tent, daypack, tarp, and sleeping bag. They also allegedly stole airline tickets and a passport from Carey.

The three were arrested Oct. 7 outside a dining hall in Portland, Oregon, after investigators traced them there with the GPS in Carter's car.
