On Saturday, June 4 at around 4 a.m., Oakley police dispatch received the report of a shooting at the O’Hara Park Middle School park, located at 1100 O’Hara Park Ave. Upon arrival, officers found Didio lying on the ground. He had sustained a gunshot wound and was pronounced dead at the scene.
Following a tip from a local resident, officers arrived at a residence on Douglas Road late Sunday evening and found Zesati, who was taken to police headquarters and interviewed by officers and detectives from the Contra Costa County Office of the Sheriff Investigation Division. He was arrested immediately following the interview.
“We’re confident we have our shooter and that the suspect is connected to a street gang,” said Oakley Chief of Police Bani Kollo. “This in an ongoing investigation, but I can tell you it’s never going to make sense. It’s such a senseless tragedy.”
Kollo said the relationship between the suspect and victim is currently unknown and that motives for the crime are being explored.
Saturday’s incident marks the second homicide this year in the normally quiet city. “I can tell you this has fairly rocked our community,” said Kollo. “This is so unusual for Oakley. We don’t see violence of this kind at any level, much less a gang level. It’s hit everyone very hard.”
Those with information about the case should call 925-313-2600.
