When Audrey Carey met Morrison Lampley, Sean Angold, and Lila Alligood in San Francisco's Golden Gate Park in October 2015, the Canadian backpacker thought she'd found new friends. "She trusted you, you three unspeakable monsters … And you stole her from me," her mother said in a statement read out in a San Rafael courtroom on Tuesday, per the San Francisco Chronicle. Both Lampley, 24, and Alligood, 19, had pleaded guilty to murdering 23-year-old Carey and later 67-year-old Steve Carter. During a preliminary hearing, Angold, 25—who took a plea deal in exchange for testimony against the pair, per NBC Bay Area—said the three were using marijuana, heroin, meth, and LSD leading up to their crimes, which began when they stole a handgun from an unlocked truck in San Francisco.
The group then befriended Carey with the goal of robbing her, Angold said. But after Alligood got her to the ground, Angold said he heard gunshots and Lampley told him, "She's dead, dude. Don't worry about it." Three days later, Lampley shot and killed Carter, whom the group had targeted for his station wagon, as he hiked with his dog in Marin County, Angold said. Authorities soon after tracked the vehicle to a soup kitchen in Portland, Ore., where the suspects were arrested. Lampley was sentenced Tuesday to 100 years in prison for first-degree murder. Alligod received 50 years but will be eligible for youthful offender parole in 25 years. Angold was given 15 years for second-degree murder. All three asked for forgiveness for their crimes, reports KRON.
