Potential Threat Tightens Security as Schaffhausen Trial Resumes
Aaron Schaffhausen's insanity defense will resume at 8:30 a.m. Monday.
Schaffhausen has already admitted to killing his three daughters. Now, his attorneys are trying to prove he was insane when he did it.
Once the defense wraps up its case, the prosecution has 120 people on its list of witnesses.
Meanwhile, St. Croix County authorities say security will be tighter Monday at the western Wisconsin courthouse where Schaffhausen is on trial.
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 Schaffhausen trial.
The statement says access to the Government Center will require security screening starting Monday.
