MENASHA, Wis. (AP) -- Private businesses provided boats and a helicopter to help search for a Neenah woman who's been missing since last Saturday afternoon, but there's still no sign of her.

Officers found Victoria Landers' car Tuesday at a park on Little Lake Butte des Morts in the town of Menasha. Someone reported it was there since Saturday night.

The 57-year-old woman's keys and purse were in the unlocked car. Her dog was left unattended at her home.

In yesterday's search, police used a dredge team's pontoon boat to get divers to deeper water. Alongside were private K9 teams. A private helicopter took an officer aloft.

Police say they've also interviewed family members and begun searching the woman's financial and computer records as part of the investigation.
