Richard Smith of Lockport IL said voices and music were repeatedly heard inside the wall in daughter Brianna's room and he eventually determined something inside the wall was picking up a local AM radio station.
The Christian radio station AM 1160 sent out an engineer to investigate the situation but the engineer was unable to identify the issue. The engineer said he opened the wall up and the electrical grounding was examined, but the was still unable to figure out where the radio station was being picked up.
He told Richard, 'I got to be honest with you. I don't know what is acting as a speaker. There is nothing I can explain of why you're actually hearing it.'
The family says it remains a mystery.
