San Francisco police are investigating three separate murders in the city.
In the first killing, police say 29-year-old Ramadan Smith was found face down in a bike lane on Post Street in San Francisco's Western Addition.
Then a little after 4 a.m., 17-year-old Reynaldo Cruz Hernandez was shot and killed while standing on a street corner in the city's Tenderloin area.
The teen was standing with two other men, leading investigators to believe that the group was targeted by a shooter in a passing car.
Police are looking for gray, four-door compact car.
In the third fatal shooting, police say a 30-year-old man was shot and killed on a Visitacion Valley street a little before 8:00 last night.
His name has not been released.
There have been no arrests in any of the shootings.
