Julian Stringer was wanted for the murder of Ralph Morales III, a 30-year-old Brentwood man who was dropped off at Sutter Delta Medical Center on June 16 with a fatal gunshot wound.
Police believe Morales had been a passenger in a vehicle when he was shot at G Street and West 17th Street in Antioch.
Witnesses allegedly identified Stringer as the shooter and police obtained a $1 million warrant for his arrest, Lt. Leonard Orman said in the days following the shooting.
Stringer, who was on parole at the time for an auto theft conviction, is also a suspect in two home-invasion robberies in Antioch and a bank robbery in Concord, according to the U.S. Marshals Service.
The California Department of Corrections had also issued a no-bail parole violation warrant for his arrest, Orman said.
The U.S. Marshal Service tracked Stringer to an apartment complex on Gardella Avenue in Reno and a Reno police officer reportedly spotted him entering an apartment Thursday evening.
Reno police obtained a search warrant for the apartment and arrested Stringer at about 7:30 p.m. after a brief standoff, Antioch police reported.
He was booked into Washoe County Jail where he will await extradition to Contra Costa County.
