A Bay Area man fatally stabbed a woman and posted video of it on Facebook, police say

SAN MATEO, Calif. (AP) — Authorities say a man allegedly stabbed a woman to death in the San Francisco Bay Area and then posted a video of the slaying to Facebook. The footage helped police track down the suspect Wednesday. Mark Mechikoff was arrested about 30 miles south of where Claribel Estrella was found dead in a San Mateo apartment complex. Authorities say Mechikoff knew the victim but the motive is under investigation. Prosecutors charged Mechikoff with a single count of murder with enhancements for inflicting great bodily injury and the use of a knife. He appeared in court Friday but did not enter a plea. His arraignment was postponed a week while a court-appointed attorney is chosen.
