A Nevada sheriff's deputy suffered a gunshot wound Friday while helping apprehend the suspect in three fatal Friday Bay Area shootings, police said Saturday.

Stefon Jefferson, 43, is a suspect in a homicide at People's Park in Berkeley Friday, as well as a shooting Friday morning in Oakland and another Friday afternoon in San Francisco's Bayview District. A fourth shooting took place when Jefferson was arrested, wounding a deputy, San Francisco police said. 

Jefferson is being detained in Douglas County on suspicion of crimes including attempted murder of a police officer, according to police. 

The People's Park shooting took place around 2:40 p.m. Friday, University of California police said. 

Officers said the People's Park shooting victim was shot by a male suspect who left the scene in a car. The victim died at the hospital, police said. 

Jefferson was arrested Friday evening in connection with a shooting Friday morning in Oakland and another Friday afternoon in San Francisco's Bayview District. University police now say Jefferson is a suspect in the People's Park shooting, as well. 

University of California police Sgt. Sabrina Reich said late Saturday afternoon that all four law enforcement agencies involved in cases in which Jefferson is a suspect are working with one another on the investigation. When asked what Jefferson's connection could be with anyone at People's Park could be, Reich said she didn't want to comment on that while that investigation is ongoing. 

Jefferson was taken into custody near South Lake Tahoe Friday evening by members of the Douglas County Sheriff's Department in Nevada, according to the San Francisco Police Department. It wasn't certain why he was in the South Lake Tahoe area, police said. 

Jefferson was booked into the Douglas County Main Jail in Minden, Nev. on charges of Attempted murder, Assault with a deadly weapon, Ex-felon in possession of a firearm, Battery on an officer, Eluding a Peace Officer along with numerous additional traffic related offenses. 

Oakland police said Jefferson was wanted in connection with a shooting in the 4100 block of Market Street in Oakland. 

Officers responded to the scene at 10:14 a.m. and located a man suffering from multiple gunshot wounds. The man died at the scene. 

At 1:27 p.m., officers with the San Francisco Police Department responded to the 1100 block of Donner Avenue in San Francisco on a report of a shooting and located a man suffering from a gunshot wound. 

The victim was transported to the hospital and later died. Investigators determined Jefferson was a suspect in that homicide as well. 

At a news conference Saturday in Minden, Douglas County District Attorney Mark Jackson said that county has first shot at Jefferson's prosecution as he is in custody there. Jackson also said he will confer with the victims' families and the district attorneys in Alameda County and San Francisco before any legal decisions are confirmed.
