The Kendall County Sheriff's Office identified the man who publicly committed suicide at the Kendall County Courthouse last week as 52-year-old John Marcus Lundberg of Yorkville.
A motive for the public display though has yet to be determined, said Deputy Craig French, spokesman for the Sheriff's office.
"That's something that we're still looking into," he said Monday afternoon.
Video surveillance from the Kendall County Courthouse showed Lundberg putting a shotgun to his head and firing a single shot Friday afternoon at approximately 1:46 p.m.
Lundberg, who was by himself at the time, parked his car on the far west side of the parking lot, according to police.
"At this point, we do not have any record that he had any criminal or civil court dates today at the courthouse,” French said Friday. “He never went into the courthouse."
