NORTH LIBERTY, Iowa — An Iowa man missing for more than a day had been texting his family from what he said was the trunk of his car.

Michael David Graham, 37, of Coralville, Iowa, sent texts saying he was tied up and forced into the trunk of his black Volkswagen Jetta while working in a commercial building here, about 100 miles east of Des Moines, according to a Tuesday morning North Liberty Police Department news release. But by Tuesday afternoon, North Liberty’s police chief, Diane Venenga, said officials less alarmed and do not suspect foul play in Graham’s disappearance.

“Family members have recently received text messages from Graham’s phone number. At this time, his location is still unknown and the circumstances of his disappearance cannot be confirmed,” the updated release states.

The last known location of Graham’s cell phone was near Keota, a city of fewer than 1,000 residents about 30 miles southwest of his work. That location came at about 1 p.m. CT Monday as Graham was communicating with his family, police said.

“He has four children and a wife who are beyond eager to have him home with us,” Graham’s wife, Jill, said in a Facebook post asking for help finding her husband.

She noted that family and police have been unable to find the 2016 Volkswagen, Iowa license plate ELL 592, leading them to assume Graham is with it.

The Iowa Missing Person Information Clearinghouse has the 5-foot-7, 160-pound man listed as missing and physically in danger as of 6 p.m. Tuesday.
