  • Two uniformed officers from Central Station were on patrol in a marked police vehicle.
  • The officers observed four individuals standing at the corner of Grant Avenue and Vallejo Street and the officers decided to contact the group of four individuals for an open alcohol container in public violation.
  • One officer made contact with the group of four individuals and engaged in a dialogue about the open alcohol container while his partner parked their vehicle.
  • After a brief dialogue between the officer and the four individuals, one of the four, later determined to be twenty-eight year old San Francisco resident Oliver Barcenas began to flee on foot on Grant Avenue towards Green Street.
  • The officer pursued Mr. Barcenas on foot and during the pursuit Mr. Barcenas removed and discarded the jacket he was wearing and drew a firearm from his waist.
