ANTIOCH -- Shots rang out late Wednesday near a memorial for a man shot to death earlier in the day, as police continued investigations into a string of recent slayings and shootings in the city.
The shooting, at about 9:50 p.m. near the railroad tracks at D Street, was one of two that occurred Wednesday evening, Antioch police Sgt. Tony Morefield said.
Police found evidence that shots were fired near a memorial set up for 21-year-old Roberto Lopez, who was gunned down at 12:26 a.m. while riding a scooter in the 1900 block of D Street, Morefield said.
No one was reported injured in the shooting near the memorial, nor in a later one that happened at 11:12 p.m. at Sycamore Avenue and Banyan Way, Morefield said.
Seven hours before Lopez was shot, the body of 70-year-old Ronald Henry Rush was discovered inside his home in the 4400 block of Horseshoe Circle. On Thursday, police said they were searching for a stolen BMW that may be tied to that case.
The 2009 BMW 325i was missing from Rush's home. The two-door sedan is gold and has a personalized California license plate of "FOXRHR."
Police said Rush had suffered head trauma, and they are treating the case as a homicide. An autopsy for Rush was performed Thursday morning, but officials did not immediately release a cause of death.
Rush's death came amid a violent span in Antioch on Tuesday and early Wednesday that also included another shooting in which a man was wounded but still ran from police.
Investigators also learned early Wednesday that an 83-year-old Antioch man who had been beaten brutally during a May 18 robbery died of his injuries.
Prosecutors on Thursday continued to review the death of Patrick Chang, who was attacked outside Orchard Supply Hardware on Lone Tree Way. He died at John Muir Medical Center on Tuesday, and the coroner's office determined the death to be a homicide.
A 15-year-old boy was arrested May 23 on suspicion of the robbery and assault. Prosecutors said they were considering whether to seek a homicide charge against the juvenile suspect.
Anyone with information on these cases is asked to call Antioch police at 925-778-2441.
