A 25-year-old rural Vernon Center man is accused of threatening his father with a sword. Timothy Truenbach allegedly raised the sword over his head and began swinging it at his father. Truenbach’s mother told authorities that she has tried to get help for her son, but he has not cooperated. He was charged with felony counts of 2nd-degree assault and terroristic threats on Thursday in Blue Earth County Court. Truenbach has prior convictions for domestic assault on two different occasions in 2007 as well, along with possession of drugs two years ago.
