SAN RAFAEL, Calif. (KTVU) -- Two Northern California drifters who were to stand trial in the murders last year of a hiker in Marin County and a visitor to Golden Gate Park in San Francisco pleaded guilty Monday to the slayings, prosecutors said.
Morrison Lampley, 24 of San Francisco, and Lila Alligood, 19, of San Rafael pled guilty to the first-degree murders of Audrey Carey, 23, and Steven Carter, 67, in Marin County Superior Court, District Attorney Edward Berberian said in a written statement.
Lampley, the alleged trigger man, was sentenced to serve 100 years to life in state prison, while Alligood was ordered to serve 50 years to life, according to the statement.
Sean Michael Angold, 25, of San Francisco, was also implicated in the slayings but he had agreed previously to testify against Lampley and Alligood and was granted immunity during a preliminary hearing. As part of the agreement, he was sentenced to 15 years to life in state prison on a second-degree murder charge, prosecutors said.
Angold testified against Alligood and Lampley at their preliminary hearing in September 2016.

Carey, 23, was making a solo trip to San Francisco's Golden Gate Park when she was slain. Her body was found Oct. 3, 2015 during the Hardly Strictly Bluegrass Festival. Carter was found two days later on a fire trail in the Loma Alta Open Space Preserve near Fairfax. He had been shot several times, authorities have said. His dog was also shot but survived.
According to reports, the drifters were arrested in Portland, Ore., after law enforcement officers tracked them using the GPS in Carter's stolen car. Police have said Lampley and Alligood were found with a handgun used in both slayings and Carey's passport.
Angold testified he stole the gun used in the murders from an unlocked vehicle in San Francisco and helped plan the robberies of Carey's backpack and Carter's vehicle and wallet.
Angold testified he walked away from where Carey was robbed in bushes in Golden Gate Park and heard gunshots. He testified Lampley told him, "She's dead dude, don't worry about it."
Angold also testified he was farther down the trail in the park when Lampley killed Carter. Defense attorneys Amy Morton and David Brown said the big question at the preliminary hearing was who had possession of the murder weapon because Angold testified he and Lampley shared its possession.
Angold testified the three drifters were using drugs he bought, including LSD, heroin and methamphetamaine during the week they traveled together in the Bay Area and to Portland, Oregon. They were arrested in Portland on Oct. 7, 2015.
As part of the agreement, prosecutors said the suspects agreed to waive their rights to appeal. Judge Kelly Simmons is scheduled to impose formal sentencing on April 18.
