St. Croix County authorities say security will be tighter Monday at the western Wisconsin courthouse where a man is on trial in the killings of his three daughters.
The sheriff's office issued a statement saying deputies responded to a "potential threat" inside the St. Croix County Government Center and Courthouse in Hudson around 9:45 a.m. Friday.
The statement says one individual was taken into custody and there's "no other known threat to the public."
Sgt. Jeff Kennett says authorities aren't providing further details on the incident. He says he can't comment on whether it's related to the trial of Aaron Schaffhausen, who's on trial for killing his three daughters at their River Falls home last summer.
The statement says access to the Government Center will require security screening starting Monday.
