MINNEAPOLIS -- A Minneapolis man is behind bars in connection with the disappearance of his ex-girlfriend Adelle "Addie" Jensen, who has been missing since Nov. 18.

Thirty-one-year-old Joshua Dow was charged Monday with second-degree assault with a dangerous weapon, and interference with a dead body while concealing evidence.

According to charges, Dow, who has a 2-year-old daughter with Jensen, went with her parents to the police station when they filed a missing persons report on Nov. 21. After Jensen's parents left, Dow returned to the station and told police that he and Jensen had recently argued because he was seeing someone else. He also told them Jensen "had left like this twice in the past - once in January and once a few week ago," according to the complaint.

ID=76484022On Nov. 22, Dow's brother told police that Jensen was dead and that he had assisted Dow in moving her body, according to charges. He told police that Dow put a gun to his head and said he would kill him if he didn't help. He said they took her body to a warehouse in Minneapolis.

Dow's brother took police to the warehouse, but was surprised to see the closet where they had put Jensen's body was empty. However, officers "smelled what their experience led them to believe was decomposing flesh," according to court documents.

A witness told authorities he had seen Dow at the warehouse on Nov. 22, washing off tarps and putting boxes on a cart.

When Dow was arrested, he told officers that Jensen had killed herself in front of him and he panicked. According to court documents, Dow told another witness that he had dismembered Jensen after she died and disposed of her body. He also admitted to police that he had disposed of her body, but did not disclose a location.

Dow is being held on $500,000 bail. He is scheduled to appear in court on Dec. 1.
