Eureka, MO (KSDK) - Police have suspended the search for a missing 12-year-old boy.
St. Louis County police were called to the Pacific Palisades Conservation Area Sunday evening to search for a boy who was last seen around 7:30 p.m.
K-9 units assisted in the search, and the dogs kept leading to the river. Divers were called in to search the water, but they found nothing.
Investigators say 12-year-old Christopher Marks is a white male, five feet three to four inches tall and approximately 130 pounds. He was last seen wearing blue or black shorts, with no shirt and no shoes. He is a seventh grader at Rogers Middle School. Family members say Chris has a twin sister.
Marks' mother, Elizabeth Combs, says her son was at the Palisades with her husband, three boys, and three girls. The boys and girls were around the ages of 15 and 16, and he was the youngest of the group.
They were there Saturday and Sunday to go swimming and barbeque. The group says Marks left around 7:30 p.m. to go rope swing on the river and no one has seen or heard from him since.
Combs says her son is a joker but "this isn't funny anymore."
Family members searched for him for a couple of hours after he disappeared before contacting police.
The Missouri State Highway Patrol issued an endangered person advisory and searched overnight into the morning.
The search was suspended Monday night, but Lt. James Mundel says the search will resume Tuesday morning at 8 a.m.
Mundel says this is still a search and not a recovery effort, and they are hopeful he will be found.
He says searchers will backtrack and sidetrack where they searched Monday.
Every possibility is being investigated, but at this time police do not believe there was foul play.
Anyone with any information about this endangered child is asked to call St. Louis County Police at 1-314-615-5360 or your nearest police agency.
