Knudsen allegedly attacked his 81-year-old father on Thanksgiving morning after the two got into a “verbal argument” a few days earlier regarding Knudsen’s unemployment status, the police report states.

In addition, the victim, also named John Knudsen, had recently told his son that he had changed his will and deed, making the younger Knudsen the sole beneficiary of his father’s fortune.

After learning about the will, Knudson allegedly went into his father’s bedroom on Thanksgiving morning and electrocuted him with two black wires. Knudsen allegedly charged at his father with the wires, pressing them on his chest and shocking him until he collapsed, according to the police report.

“The victim explained he felt a charge of electricity surge through his body which caused him to become incapacitated,” the police report reads.
