A young Michigan couple and their 4-month-old son who have been missing for nearly a month left their home "in a hurry," authorities told FoxNews.com.

Timothy Medsker, 33, his wife Sabrina Medsker, 34, and their 4-month old son Joshua, were reported missing from their Petoskey home on Feb. 23, a week after they failed to appear for several appointments, Petoskey Department of Public Safety Det. David Schultz said Wednesday.

Authorities do not believe foul play is involved in the case. Schultz said the family -- who ran a successful commercial cleaning business -- left the area by choice, but left behind sizable amounts of food, toiletries and other everyday items.

"There's nothing in the home that looks like a crime scene," he said. "But something scared them enough to leave in a hurry. It looked like they packed up and left in a hurry."

Schultz said the couple's finances were not believed to be a concern, as their bills were all up to date.

"They had a very successful small business in town cleaning offices and businesses," he said.

The couple worked long hours and were known to be "very private," Schultz said.

Relatives of Timothy Medsker are cooperating with authorities. Petoskey Director of Public Safety John Calabrese told the Orlando Sentinel that the family has ties to Orlando, Chicago and Gary, Ind., and is believed to have spent time in Arizona.

Anyone with information regarding the whereabouts of the family is urged to contact the Petoskey Department of Public Safety at (231) 347-2500.
