The Philadelphia District Attorney's Office declined to prosecute a couple who left their three grandchildren in a car at Sugarhouse Casino while they gambled last night, according to police.
The children - ages 2, 7 and 12 - were spotted alone in the car by casino security around 7:55 p.m., police said. It's believed their grandparents left them alone from around 7:45 p.m., when they parked, to around 8:30 p.m., when they emerged from the casino and found authorities at their vehicle, police said.
The grandparents, who are the children's legal guardians, were taken in for questioning but released without charges, police said. Their identities have not been released.
