The 26-year-old man worked at the YMCA's Camp Wakonda near Halltown, although the abuse for which he is charged did not happen at the camp and was not against a Wakonda camper. The YMCA fired O’Dell last Friday, the same day that police arrested him and prosecutors charged him with molesting a boy in a hotel room.

O'Dell volunteered for a short time at Pershing Middle School. One of the students with whom he worked says he’s concerned there could be more victims.

"I got to go to meet him at his house one time,” said one boy, who asked to remain anonymous.

That boy says he knew O’Dell all too well.

"He'd come over and hang out at lunch time. We'd see him at lunch and he'd help my best friend out in the classroom,” he said.

The boy says O’Dell had contact with dozens of students while he volunteered as a tutor at Pershing. The Springfield School District says O’Dell worked there for only a month. This boy and other students say it was longer.

Either way, O'Dell passed the required background check for the school and the YMCA. He had nothing on his record.

"Obviously, on occasion, there are individuals who unfortunately across the country try to take advantage of the situation,” said Marc Maness, a spokesman for the school district.

"It's very disappointing,” said the boy’s mother.

The mother says she complained to the district that O'Dell was too friendly to her son and other students. She says she was concerned something wasn't right.

"I went in and spoke with the counselor and I told them there was a gut feeling that this just wasn't right and he more or less said he'd check into it,” she said.

The mother says O’Dell gave her son a cellular telephone, and she thought it was strange but, since O'Dell worked part-time at radio station KTTS as a disc jockey, she somehow justified it in her own mind. That’s a move she now regrets.

"As a parent I didn't want him giving him gifts,” she said, “but he would always come up with, 'It's a leftover from the radio station and I'm not buying it, so it's no big deal.’”

"He actually gave me a phone but what he did is he'd take that phone from them and give it to another person when he was ready to move on to the next child,” the boy said.

Their fear is there could be dozens more victims. "If he did it, I hope he sits in jail for a really, really long time,” said the mother.

O'Dell has not been charged with any crime other than the one prosecutors say happened at a motel in north Springfield last Thursday. He's accused of enticing a 15-year old boy and sexually abusing him.

YMCA executives say O'Dell worked at Camp Wakonda for two years. They say his job was mostly administrative, not working directly with children.

A Springfield Police commander says there might be at least two other victims. Detectives are working with the Child Advocacy Center on their investigation.
