The backstory:
Hairston is accused of shooting Santa Monica Police Department Officer Lucas Palmeira near the Santa Monica Place Mall on Wednesday.
But, Hairston's alleged crime spree began on Sunday, June 22, when two children, aged 14 and 16, were shot inside a driverless Waymo near Second Street and Broadway. SMPD Lt. Lewis Gilmour said they believed the shooting might have happened after Hairston and the children in the Waymo had gotten into an argument.

Then on Wednesday, officials said Palmeira found Hairston near Fourth Street and Colorado Avenue, and recognized him from a bulletin on the Sunday shooting. When Palmeira approached him, Hairston took off running. That's when Hairston allegedly shot Palmeria, and kept running.
Police locked down the area for several hours searching for the suspect. Police said they got a tip that led them to Hairston's location. Officers arrested Hairston in Pacific Park on Wednesday, after the hours-long manhunt. SkyFOX was live above the scene as officers took Hairston into custody.
