Alcohol and a prescription drug were found to be contributing factors in a fatal Memorial Day weekend motorcycle crash near Seneca, according to the Grundy County Coroner's Office.

Coroner John Callahan said in a release Thursday that Anthony R. Cutrano, 52, of Palos Heights, Ill., had a blood alcohol level of .234 at the time of the crash, which occurred at about 3 p.m. May 27, on U.S. 6, two-tenths of a mile north of Bluff Road. In Illinois, one is considered intoxicated when their blood alcohol content reaches .08.

Diazepam, a prescription drug that is a muscle relaxant, was also found.
