The murdered woman, Marina Johansson, was last seen alive in July, 2010. Her ex-boyfriend was arrested soon after, even though there were no indications that the woman was dead, and nothing incriminating had been found by police at the woman's house. Five months later, people moving into her house found a blood-soaked mattress and a bullet in the wall.
It wasn't until almost two years later that the body of the 31-year-old Johansson was found hidden inside another mattress in the woods, discovered by volunteer search organization Missing People. The mattress was hollowed out to make room for the body, and partially concealed by large pieces of wood. Johansson's identity was confirmed through her dental records.
Her ex-boyfriend, who had been arrested, tried, and acquitted twice since her disappearance, will be arrested once more and detained ahead of the new Supreme Court trial.
"The Supreme Court has concluded that it remains uncertain that the ex-boyfriend would have been convicted in accordance with the indictment if the new evidence had have been known at the time of the trial," the court wrote in a statement released on Friday.
Head prosecutor Urban Svenkvist told the TT news agency that he thinks the "chances are good" that the man will be convicted for Johansson's murder.
