FOND DU LAC, Wis. (AP) -- Fond du Lac County sheriff's deputies believe a man with a gun is still holed up in a Campbellsport duplex.
A woman called for help about 10 p.m. Monday, saying the man had fired a handgun inside their home after the two argued. Sheriff Mick Fink says the woman was able to flee the home during the night.
SWAT team members surround the house. Tenants in the other half of the duplex have been evacuated.
Fink says officers are trying to negotiate with the man, but don't know for sure if he's still in the house.
The sheriff says the recent death of a Fond du Lac police officer who was shot during a standoff March 20 is top of mind for the deputies covering this call. The sheriff tells The Fond du Lac Reporter that they will be slow and deliberate in their response to the situation.
