State and Skowhegan police joined game wardens in searching a home for evidence related to the disappearance of Tina Stadig, 40.
She was last spotted at the Bangor Area Homeless Shelter while trying to find a place to stay.
Her family said she suffered from mental illness and believed someone was trying to kill her.
What brought them to a home on Route 150 in Skowhegan today is unclear.
The home is owned by a man who is friends with Stadig and she stayed there on occasion.
Crews have been searching the home along with a nearby wooded area.
Three police tracking dogs were also called to the scene to look for evidence.
