The crash happened back in March in Crest Hill, police said.
Mary Beth Mosqueda has been charged with two counts of failure to report an accident involving personal injury or death, Crest Hill police announced Wednesday. She is not yet in police custody.
Police responded just before 11 p.m. on March 9 to the 2100-block of Plainfield Road after reports of a pedestrian being hit by a vehicle, law enforcement officials said at the time.
Laurie and Danny Cooper of Plainfield were found dead in the road at the scene of the crash.
