MEDFORD, Wis. (WRN) — A suspect allegedly responsible for the deaths of a couple last week, has also been found deceased.

Taylor County Sheriff Corey Dassow said 15-year-old Kayden Hadden, was located in his vehicle, on Saturday in Price County, deceased of a self-inflicted gunshot wound.

A manhunt for Hadden was underway Friday related to the deaths of 44-year-old Josh Mann and 43-year-old Rebecca Mann. The couple were found deceased in their home last Wednesday and Hadden was a person of interest, prompting a regional manhunt for him and the silver Chevy Impala he was driving.

The sheriff later said Hadden was responsible for their deaths and that Hadden acted alone.

The motive for the killings and how the teen knew the couple was not released at this time. The homicides were under investigation.
