Hyungseok Koh was found not guilty by a Cook County jury Monday on all counts related to the death of his 22-year-old son, Paul Koh, in 2009, the Chicago Tribune reports.
Koh had allegedly confessed to the murder, but his lawyer sowed doubt in the jurors' minds that Koh, whose native language is Korean, fully understood what police were asking him, the article says.
The alleged confession came while Koh was in police custody shortly after his son's April 16, 2009 death, when Paul Koh was found stabbed in the doorway of the Kohs’ Birch Road home.
Northbrook Police responded to the Koh residence around 3:44 a.m. that day after Hyungseok Koh called 911. When they arrived, Koh ran out of his garage door screaming, then brought officers to his front door, where his son lay dead in a pool of blood, according to court documents.
