An anonymous donation of $6,000 has increased the reward for information leading to the location of Jessica Heeringa and the prosecution of her abductor to over $21,000.

Heeringa has been missing exactly one year today after she was allegedly abducted while finishing her shift as a night clerk at the Sternberg Road Exxon gas station in Norton Shores, shortly before 11 p.m.

Anyone with information regarding Jessica's abduction one year ago today is asked to call Silent Observer (231-72-CRIME) or the Norton Shores Police Department (231-733-2691).
