A Minneapolis man was sentenced to 20 years in prison on Wednesday in the death of his girlfriend, Adelle “Addie” Jensen, who disappeared four years ago and whose body has never been found, prosecutors announced. Hennepin County Attorney Mike Freeman said Joshua Dow, 35, received 20 years in prison as part of a plea agreement, adding that he pleaded guilty last month to second-degree murder in the death of his child’s mother, who was 25-years-old at the time of her death.
