ROSEBURG — The mother of missing Oregon boy Kyron Horman and others are distributing fliers urging the public to ask the boy's stepmother where he is.

The fliers are being handed out in Roseburg, the town where the stepmother, Terri Moulton Horman, is from. The biological mother, Desiree Young of Medford, was in Roseburg Saturday to unveil the fliers, which have photos of her son and his stepmother.

Investigators have focused on Terri Horman but haven't called her a suspect.

Kyron has been missing since June 4, when the 8-year-old disappeared after a science fair at his elementary school. Terri Horman was the last person known to have seen him.
