DORR, Mich. (WZZM) - Police have called off a manhunt in Allegan County for two fugitives who have been on the run since this weekend. Gregory Bradshaw and Kenneth Grauman II were seen around 4 p.m. Monday along 142nd Avenue in Dorr. But now it appears they may have eluded police.

The Allegan County Sheriff says that while no air or ground search is currently underway, they are investigating tips called in to the department.

The men escaped from the Lake County Residential Reentry Program on Saturday. Authorities believe they were traveling in a green 2000 Jeep Cherokee Sport with Michigan license plate CLX 3644. The vehicle was stolen from Kent County.

Monday afternoon, authorities set up a perimeter along 142nd 21st St. Allegan County deputies, Michigan State Police, and U.S. Marshals were all involved in the search. A member of the public also used an ultra-light aircraft in the search until a Michigan State Police helicopter arrived.

It's believed the Bradshaw and Grauman ditched the green Jeep and are traveling on foot, hiding in a wooded area. Residents are being advised to lock their doors and call 911 if they spot anything suspicious.

Grauman and Bradshaw have criminal records involving weapons, assaults and drug offenses. Police say they have friends and family in Allegan County they may attempt to contact. Grauman is 5' 10'' tall, weighing 155 pounds with red hair and blue eyes. Bradshaw is 5' 11'' tall, weighing 185 pounds with brown hair and blue eyes.
