Riverside Sheriff investigators brought in heavy equipment over the weekend to search for the remains of Dia Abrams on her ranch near Idyllwild. The former La Jolla woman went missing from the ranch in 2020. Her body has not been found. Neighbors woke up early Sunday morning to the sound of a sheriff helicopter flying over the ranch in Mountain Center. On a loudspeaker, officers told Abrams' boyfriend and ranch manager, Keith Harper, to come outside because they were serving a search warrant, according to a witness. Neighbors recorded video showing about a dozen law enforcement vehicles driving onto the 117-acre Bonita Vista Ranch.
