Sheriff Describes Discovery Of Missing Woman's Car Sheriff Hopes Evidence Will Lead To Woman's Discovery

Judith Mattise, 55, was last seen leaving her home on May 19 in a silver 2003 Chevrolet Impala with Michigan license plate number 3AQW95.

A towing company clearing abandoned cars on the streets of Detroit found the vehicle on Sept. 16 parked on Adelaide Street near Comerica Park, according to police.

Police believe the vehicle may have been sitting at that location for months. It was reportedly infested with two nests of bees -- one in the trunk and one near the front passenger door.

Deputies also discovered inside the car what appeared to be Mattise's purse, which contained some personal belongings and cash, Local 4 reported.

"We still haven't been able to make a determination as to how valuable some of that evidence or property that was in the car is at this point in time," said Macomb County Sheriff Mark Hackel.

Mattise's husband, Jim, 61, was found dead on May 21 in his car with a suicide note next to him, according to police. Investigators say he strangled himself using a plastic zip tie.

Police believe Judith Mattise (pictured, above) may also be dead, but they have not ruled out other possibilities in the case, Local 4 reported.

The new clues have reportedly helped further the investigation including a search last week in the 23 Mile Road and Gratiot area. Nothing was found, but police are hopeful that tests by forensic experts on the items found in the car will help in their investigation.

Mattise is described as a 5-foot-7-inch tall, 145-pound white woman who has blond hair and blue eyes.

Anyone with information on the woman's whereabouts has been asked to contact the Macomb County Sheriff's Department at (586) 469-5151.
