On Wednesday, October 27, 2021, at approximately 5:50 PM, San Francisco Police officers from the Bayview District Station responded to the 1400 block of Shafter Ave. regarding a dog that was just stabbed.

Upon arrival, officers contacted a 50-year-old female victim who was holding her Terrier mix dog that was suffering from a stab wound. Officers immediately rendered aid to the dog and transported the dog to the animal hospital with life-threatening injuries. The victim stated that she and her dog were sitting in her parked vehicle when a male without provocation brandished a knife at the victim, threatened the victim, then proceeded to stab the dog through the vehicle window and walked away. During the investigation, the suspect, 35-year-old male Derrick Juan Strong of San Francisco, was located and arrested by officers near the scene of the stabbing. Officers conducted a search of the suspect and located and seized a knife that was in his possession.

Officers developed probable cause to arrest Strong for criminal threats (422(a) PC), maliciously injuring an animal (597(a) PC), and brandishing a weapon other than a firearm (417(a)(1) PC) for this unprovoked violent attack.

Thanks to the quick response and actions of the officers who immediately rendered aid and transported the dog for his life-threatening injuries, he is now at home recovering with his family. This news release is accompanied by a photograph of the dog after undergoing emergency veterinarian care.
