Authorities are searching for 10-year-old missing Michigan boy Devon Morrison, who disappeared Saturday and was last seen carrying a fishing pole.

After a search Sunday night ended without finding Devon, federal, state and local authorities were expected to renew the search Monday morning, the Grand Rapids Press reported. Searches conducted Sunday morning along the river and in adjacent fields yielded no signs of the missing 10-year-old Belding, Mich., boy, according to the Detroit Free Press. But local police discovered what may be Devon’s sneakers on the banks of the Flat River on Sunday morning.

The search Sunday included divers from a number of police agencies, while the Michigan State Police joined the search by providing a helicopter.

Crime scene tape was placed around the perimeter of the Morrison home after detectives searched the residence Sunday night, WWMT reported. The paper said it observed detectives taking photographs inside the home and spoke to someone in the house “for a period of time.” Investigators spoke to Devon’s mother, her boyfriend, and the 10-year-old’s grandmother, but did not label them as suspects in the 10-year-old’s disappearance. Dogs were also aiding in the search at the house.

The 10-year-old’s family said he typically fished on the Flat River in western Michigan and that he routinely fished alone and came back home after a few hours.

“This time he didn’t come back,” Belding Police Chief Dale Nelson told the Free Press.

Devon left to fishing around 10:30 a.m. Saturday, and was last seen by a neighbor later that day at 2:30 p.m., according to the Grand Rapids Press. He was reported missing at 6:15 p.m. after he didn’t check in with his family, which he usually does every two hours.

The 10-year-old Belding boy was last seen wearing black jeans and a red hoodie with the word “starter” emblazoned on it in white.

Sgt. William Hoskins of the Ionia Police Department told the search party what to be on the lookout for.

“You’re looking for anything: clothes, blood, tools, anything that doesn’t look to you like it belongs there,” Hoskins said. “If you find a fishing pole, we need to know it.”

Nelson, who said his son plays baseball with Devon, said the missing boy has attention deficit disorder.

“He moves to his own drum sometimes, but he’s a good kid,” the Belding police chief added. “Every time you see him, if he doesn’t have a ball glove, he has a fishing rod. If he’s out there, I think he’ll make the right choice and come back.”

Nelson urged anyone with information on Devon’s disappearance to call Ionia Central Dispatch at 616-522-0911.
