A Santa Barbara man was arrested on suspicion of stalking a woman in Isla Vista.
Sheriff's officials say they began an investigation into 43-year-old Zachary Coughlin last week after receiving various reports from locals concerned about his postings on social media that referenced the mass murder that occurred in Isla Vista in 2014.
The sheriff's office says detectives interviewed witnesses and combed through social media and discovered that Coughlin was actively stalking someone.
Coughlin was arrested Monday and booked into Santa Barbara County Jail with bail set at $200,000. The converted bus that he was living in was also towed from Isla Vista.
Sheriff's officials say they are continuing to investigate Coughlin and anyone with information that may help detectives with this case are urged to contact the Special Investigations Bureau at InfoSIB@sbsheriff.org.
