Medical authorities say it was 30-year-old Keith Zinn who was gunned down in broad daylight yesterday morning in the city's Bayview neighborhood.
Just before 10 a.m. on Monday, police were called out to the intersection of Ironwood and Catalina Street where they found Zinn, a San Francisco resident, with a gunshot wound. He was pronounced dead at the scene, police say.
Zinn was one of four men killed in a slew of shootings over the Fourth of July holiday weekend. On July 4, at about 10:06 p.m., 49-year-old Wesley Willis was sitting inside a car parked at Harbor Road and Ingalls Street when an unknown person walked up fired multiple shots, killing him.
A day later, 37-year-old Antonio Cortez was standing outside a residence on the 1700 block of La Salle Avenue when he and another man were shot in the chest and back. Cortez died three hours later at a local hospital. The second victim remains in critical condition.
Then on Monday morning, a man in his 20s was shot to death near the Sunnydale housing projects. The Coroner's Office has not yet identified the victim. About six hours later, more gunfire erupted in the city and Zinn was killed.
