PORTLAND, Ore. - A man accused of hiring a hit man to kill his wife is now facing two new and more severe charges.
Michael Kuhnhausen, Sr. originally faced charges of attempted murder and conspiracy to commit murder.
After hearing from three more witnesses, the grand jury has added charges of aggravated attempted murder and conspiracy to commit aggravated murder.
If convicted, Kuhnhausen could now spend 10 years in prison. The old charges carried a maximum sentence of less than eight and a half years.
All four counts stem from the Sept. 6 attack on 51-year-old Susan Kuhnhausen at her southeast Portland home. When she arrived home from work, an intruder attacked her with a hammer.
She fought off the man and strangled the attacker to death with her bare hands. Prosecutors say that attacker, Edward Dalton Haffey, was hired by Michael Kuhnhausen to murder his wife.
The new charges came after new witnesses verified that Kuhnhausen plotted the murder with Haffey.
Details of the testimony are sealed in the grand jury indictments.
