One man was fatally stabbed and another shot to death in San Francisco in the last few days, bringing the city's homicide count for 2016 to seven.

According to San Francisco Police Department spokesperson Officer Albie Esparza, police were called to the corner of Turk and Leavenworth Streets at 7:41 Thursday evening after 911 callers reported a violent altercation was underway.

When officers arrived at the Tenderloin corner, they discovered two stabbing victims: A man and a 42-year-old woman. Both were transported to San Francisco General Hospital, where the male victim died, Esparza says. According to the San Francisco Medical Examiner, the dead man has been identified as SF resident Donnie Smith.

Esparza says that witnesses saw the injured woman and another woman engaged in a fight. When the male victim attempted to break up the altercation, another bystanding man confronted him and "stabbed him several times."

Citing SFPD's ongoing investigation, Esparza could not provide any additional details on the relationship between those involved in the fatal incident.

At present, Esparza says, it's also unclear which of the participants stabbed the woman. Her injuries aren't considered life-threatening, and she's expected to survive.

The other woman and the stabbing suspect both fled the scene, and haven't been spotted since. As of this morning, Esparza says, no arrests have been made.

In San Francisco's second homicide in recent days, a 19-year-old man was shot to death in a Bayview Apartment Saturday afternoon.

Esparza says that at 4:03 p.m. Saturday, police were called to an apartment on the 200 block of Harbor Road, which is near Ingalls Street.

When they arrived, they found an 18-year-old man identified by ME's office as San Francisco resident Kijana Wood. Wood had been shot "multiple" times, and had succumbed to his injuries before SFPD arrived, Esparza says.

(This isn't that block's first fatal shooting: back in October 2014, a man in his 20s was shot to death on that same stretch of street.)

The suspect, a 42-year-old SF resident named Verdell Cornealis Martin, was arrested at the scene., and has been booked into San Francisco County Jail on suspicion of murder. Additional details in the shooting were not available at publication time.

San Francisco's last homicide was on February 21, when SF resident Curtis Cail was shot to death as the vehicle he occupied left the McDonald's at Fillmore and Golden Gate. As of Monday, no suspects have been arrested in that slaying.
