Joshua Waring, son of former “Real Housewives of Orange County” star Lauri Peterson, did not have gunshot residue on his hands or clothing after his arrest in connection with a Costa Mesa shooting last year, according to an analysis performed by the Los Angeles County Department of Medical-Examiner Coroner.RELATED: 'I wouldn’t do this,' son of ex-'Real Housewives' star says of attempted-murder allegations
However, forensic experts cautioned against drawing the conclusion that the analysis supports Waring’s claim that the test results could exonerate him of attempted-murder charges.
Such tests are performed to help determine whether a suspect recently fired a gun.
Waring, 28, has been in Orange County Jail for 10 months in connection with a drive-by shooting in June outside a home in the 2900 block of Babb Street that left a man severely injured.
Waring said during a jailhouse interview with the Daily Pilot last week that the results of the gunshot-residue test, which he said was administered after his arrest, could exonerate him. Waring received the results Monday.
However, Debra Gibson, acting chief of forensics laboratories for the Los Angeles County coroner’s office, wrote in the analysis report, dated in February, that the findings are inconclusive.
