A 19-year-old male was stabbed multiple times at about 2:20 a.m. Saturday on the 200 block of Leavenworth Street for no apparent reason. A 32-year-old suspect, who was later arrested and identified as Ernesto Tun-Catzin, walked up to the victim and his friend and challenged him to a fight. An altercation ensued in which the victim was stabbed and his friend was punched. The friend was able to give police a description of the suspect, who was later arrested a few blocks away.
The 19-year-old victim was hospitalized with life-threatening injuries, and remains there.
The suspect was with a group of people at the time of the incident, and the investigation is ongoing. Anyone with any further information is asked to call the SFPD's anonymous tip line at (415) 575-4444 or send a text to TIP411.
This marked the first of two stabbings over the weekend, with the second claiming a female victim, who is expected to survive.
