Court documents released say the boyfriend of pregnant 18-year-old Eieen Viveros-Varga admitted to fatally shooting her.
Luis Chacon-Villeda admitted to the shooting in St. Paul but claims that it was an accident. Documents show that Chacon-Villeda was the person who placed the 911 call and told the dispatcher that he was the one who fired the shot.
Officers arrested him on suspicion of murder, but he was later released and charged with drug charges.
The shooting remains under investigation.
