Five people were killed, a man was found dead under suspicious circumstances, and another man was clinging to life from a gunshot wound — a grisly three-day tally of violence that boiled over in San Francisco through the weekend.

A lone suspect was arrested in one of the killings, police said. The spate of attacks happened in neighborhoods around the city.

Police did not say if they believe any of the slayings are linked and investigators did not release a motive in any of the deaths.

The first killing happened at 4:30 a.m. on Friday near Polk and Ellis streets in the Tenderloin. The 24-year-old victim, who was not identified, was shot by an unknown assailant. Paramedics took the victim to San Francisco General Hospital, where he died.

That same day, 43-year-old Demetrius Jones was gunned down on the 900 block of Ellsworth Street near Interstate 280, south of Bernal Heights. Jones was pronounced dead at a hospital from a gunshot wound.

On Saturday, shootings claimed the life of one man and left a 19-year-old man with life-threatening injuries.

The teenage victim was hit by gunfire at 2:05 p.m. on the 200 block of Hahn Street in Visitacion Valley. Two hours later, and only two blocks away from the Hahn Street shooting, 36-year-old San Francisco resident Giovanni Hernandez was shot and killed on Burr Avenue.

The weekend of violence was capped Sunday with three deaths.

Around 2:30 a.m., two suspects in their late 20s opened fire on three men on Sixth and Bryant streets in the city’s South of Market neighborhood. All three victims were hit by gunfire and taken to San Francisco General Hospital, where one, an unnamed man in his 40s, died. The other victims, men in their mid-20s, were expected to survive.

Investigators are also working to determine how a 23-year-old man died on Chumasero Drive, a road connecting Brotherhood Way and Font Boulevard in the Parkmerced neighborhood, just north of San Francisco Golf Club. Police found his body around 4:20 a.m. and have called the death suspicious.

Later that day, a woman in her mid-60s was stabbed to death by a man on the 2600 block of California Street in the Lower Pacific Heights neighborhood. Police did not include details of the killing or a motive, but authorities said they arrested a 59-year-old suspect in the killing.

The suspected killer was not immediately named.
