A man who allegedly fired about a half-dozen gunshots into an unoccupied parked car from inside a Mountain View home Friday prompted a brief SWAT standoff that ended in his arrest. The non-injury gunfire on Vista Horizon Street erupted about 6 a.m., according to the San Diego Police Department. A witness reported that her husband’s vehicle had been struck by gunfire and other callers said they had heard between three to six gunshots, Lt. Nydia Castro said in a news release. When officers arrived, the suspect refused to exit the apartment and surrender, Officer David O’Brien said. About an hour into the stalemate, police sent in a SWAT team. The standoff continued until shortly before 8 a.m., when the suspect voluntarily walked out of the home and gave himself up. It was unclear why he allegedly shot up the vehicle. A semi-automatic rifle with several rounds of ammunition was found inside the apartment, police said. The 45-year-old gunman was arrested on suspicion of attempted murder and other firearms-related charges, Castro said. Staff writer Caleb Lunetta contributed to this report.
