Kayla Berg was 15 and from Antigo, Wisconsin, when she was last seen the night of August 11, 2009. That evening she was with a 24-year-old friend, Kevin Kielcheski, who later said he dropped her off at a condemned house in Wausau about 40 minutes away. He reported no one was home and said he did not see her go inside. Kayla’s family says there was no reason for her to go to that property and do not believe she would have gone there voluntarily.

Her disappearance was not reported for six days after a misunderstanding between her separated parents, each thinking she was staying with the other. Authorities initially treated the case as a possible runaway; investigators now suspect foul play. Kielcheski was charged with second-degree reckless endangerment over drug use with Kayla the night she vanished, but those charges were later dismissed. Kayla was 5 feet 2 inches, 108 pounds, with brown hair and brown eyes; she was wearing a red spaghetti-strap top, a blue hooded sweatshirt, and tan sandals when last seen.

No conclusive evidence has been found and the case remains unsolved. If anyone knew Kayla, saw her that night, or has information about the condemned house in Wausau, please come forward.
