A man, already on the sex offender registry, is facing charges for allegedly molesting a 10-year old boy.
Douglas Hahn was convicted of sodomizing two girls in St. Louis County in 1992. The new charges stem from allegations that were brought to the attention of the Warren County Sheriff's Department earlier this month. Prosecutors say that Hahn abused the boy in 2002 while the boy's father was living at Hahn's house. .
Hahn is held on a half-million-dollar bond.
