MINNEAPOLIS — A Minneapolis man currently in prison on separate charges will add a 20 year sentence to his stay, after striking a deal to plead guilty in the 2015 murder of his girlfriend. 

Joshua Dow admitted his guilt in the death of Adelle Jensen, who was also the mother of his child. In court Thursday, Dow said that his actions with his gun, which he still claims Jensen was holding, caused her death. Jensen disappeared the night of Nov. 18, 2015 and her body has never been found. 

"This is a very good outcome for Ms. Jensen’s family and for justice in general,” said Hennepin County Attorney Mike Freeman in a written statement. “It was a difficult case because we did not have Ms. Jensen’s body. But Mr. Dow realized that the unremitting investigation by Minneapolis police had put together an excellent circumstantial case which we could use to successfully convince a jury of his guilt. He did the right thing by pleading guilty.”

Investigators say Dow, his brother and Jensen were in downtown Minneapolis that night when she left the brothers around 2:30 a.m. and went back to Dow's home in north Minneapolis. The couple had separated but still did things together. 

The timeline put together by homicide detectives says Jensen was shot around 5 a.m. that morning. They say Dow took Jensen's body to a warehouse where he had worked and stuffed it into a locker. Over the next few days police say he dismembered the corpse and hid the remains at multiple sites. Investigators say he also forced his brother to help him cut up a couch with Jensen's blood on it and dispose of that evidence as well. 

Dow is currently in prison after being convicted in 2016 for interference with a dead body and first degree drug sale. He was three months from a possible release when he pleaded guilty to Jensen's murder.
