Three men and one woman died violent deaths in separate San Francisco incidents this past weekend, while a fifth perished under conditions police characterize as "suspicious" pending further investigation.

Here's the rundown of what appears to have been an especially brutal weekend:

As of Monday morning, no arrests had been made in the slaying. This was the second homicide for San Francisco Friday, following the 4:30 a.m. slaying of San Francisco resident Mitchell Warren in the Tenderloin.
  • Saturday, October 1, at 4 p.m.: A man identified by the ME as 36-year-old San Francisco resident Giovanni Hernandez was shot on Burr Avenue, a short street near the Cow Palace. He was transported to an area hospital, where he died of his injuries. Police describe the suspect in the slaying as an "unknown male" and say that no arrests have been made.
  • Sunday, October 2, at 2:29 a.m.: Police say that two men in their late 20s shot at three men near the intersection of Sixth and Bryant Streets. 26-year-old Stockton resident John Sanyaolu was killed, the ME's office confirmed, while two other men (one aged 28, the other aged 26) were injured. The suspects in the shooting remain at large as of Monday morning.
  • Sunday, October 2, at 4:45 p.m.: According to the San Francisco Police Department, a woman in her early 60s was stabbed to death on the 2600 block of California Street, which is between Pierce and Scott Streets.

In addition to those four homicides, police are investigating a "suspicious death" they place at 4:20 a.m. on Sunday. According to the SFPD, a 23-year-old man was found dead on Chumasero Drive, in Parkmerced.
