One person was killed and four others were critically wounded in a mass shooting early Thursday morning in San Francisco's Tenderloin neighborhood, police said.
Officers responded to reports of gunfire in the area of Hyde and Turk streets around 2:30 a.m. and found four men and one woman shot, the San Francisco Police Department said. All five victims were taken to a local hospital, where one man eventually died.
The other four victims were hospitalized with life-threatening injuries, according to authorities. Their conditions were not immediately made available Friday.
Homicide detectives are investigating the shooting. Police did not release any information on the circumstances surrounding the incident or provide any suspect details.
The San Francisco Medical Examiner's Office did not immediately respond to The Standard's request for comment on the victim's identity.
The definition of a mass shooting is not entirely agreed upon. The FBI defines it as an incident in which four or more people are slain with a firearm. Other groups define it as three or more people killed or injured in a shooting.
