FORT WAYNE, Ind. — The FBI has joined the search for a missing 9-year-old Indiana girl and agents are scouring a mobile home park that's also a haven for registered sex offenders.

Agents on Monday descended on the mobile home park where Aliahna Lemmon lived in Fort Wayne.

A sheriff's department spokesman says Fort Wayne authorities plan to meet Monday afternoon to plan their next move after two straight days without a search for the girl. Aliahna went missing from a family friend's home on Friday.

About a half-dozen people in black windbreakers were at the mobile home park Monday. Several identified themselves as FBI agents.

Search dogs were seen at a nearby storage facility.

A state website says 15 registered sex offenders reside at the mobile home park.
