Someone had been dumping adult diapers in upscale neighborhoods in Orange County, so police set up surveillance and found diapers with an envelope addressed to a medical office.
The address led investigators to watch a multimillion-dollar Newport Coast home. Officers followed a 67-year-old man on Tuesday, pulled him over and found dirty diapers in his passenger seat.
The man, whose name has not been released, has not been arrested, but police say they are pursuing a case with prosecutors.
Police say the illegal dumping of dozens of dirty diapers started last year in Newport Beach and Laguna Beach. The diapers were thrown out mostly along Coast Highway in Newport Beach, and within the traffic lanes between the north city limits of Laguna and the Emerald Bay main entrance.
