Los Angeles, California (CNN) -- Skeletal remains found in a remote area of Malibu Canyon on Monday are those of Mitrice Richardson, a California woman who disappeared last year, Los Angeles County Sheriff Lee Baca said Thursday. Richardson, 24, was last seen leaving a sheriff's station in Malibu after being detained by sheriff's deputies on a citizen's arrest complaint made by a restaurant manager in September. "We have no indication of a homicide at this point," Baca said. "I don't believe that the remains are capable of telling us a story." The remains, which included a human skull, were found Monday by park rangers searching the area for marijuana groves, said Los Angeles County Sheriff's spokesman Steve Whitmore.
