Three people suspected in the shooting death of Steve Carter, 67, a tantra yoga teacher whose body was found Monday along a hiking trail outside San Francisco, his wounded dog still attached to his hand by a leash, were booked on murder warrants, police in Portland, Oregon, said Thursday.

Sean Michael Angold, 24, Lila Scott Allgood, 19, and Morrison Haze Lampley, 23, were booked into Multnomah County Jail and arraigned Friday, NBC Bay Area reports. The trio waived their rights to an extradition hearing and will be transferred to San Francisco.

A handgun reported stolen on October 1st from the Fisherman’s Warf neighborhood in San Francisco was recovered when the suspects were arrested Wednesday at a soup kitchen in Portland, the Associated Press reports.

The three, which according to the AP authorities have described as “drifters,” are also suspects in the earlier shooting death of Audrey Carey, a 23-year-old Canadian tourist on a backpacking trip who was found shot in the head in San Francisco’s Golden Gate Bridge Park, on October 3rd, after the first day of a music festival there.

“We believe the same weapon was used in both crimes,” police commander Toney Chaplin said on Friday. He added that it appears as though the motive for the two killings was robbery: when they were arrested, the suspects were in possession of Carter’s car and some of Carey’s camping gear.
