Watertown police say they were called to check on the welfare of Douglas Teuteberg Friday.
Officers tried to call the 52-year-old father, then went to his house and found Teuteberg and his 16-year-old son dead.
Officials did not disclose how the two died or name the teenager.
Since Teuteberg was a former Watertown officer, police contacted the Dodge County Sheriff’s Office to investigate.
The Wisconsin Department of Justice’s crime scene unit also responded.
