(CBS) MINNEAPOLIS - A medical examiner says Kira Trevino, a 30-year-old Minnesota woman whose body was recovered from the Mississippi River on Wednesday, had suffered several injuries, including a head wound, a broken finger and bruising inside her upper lip. She also had suffered from lacerations to her liver, CBS Minnesota reports.
Authorities say they will need to investigate further to determine if the injuries occurred before or after her death.
Trevino's body was discovered Wednesday along the Mississippi River in St. Paul, Minn. by a local worker. The Ramsey County Medical Examiner used dental records to identify the body as that of Trevino, who had been missing since Feb. 21.
Court documents obtained by CBS Minnesota reveal Trevino was found without clothing and was not wearing any jewelry.
During an autopsy, authorities reportedly found duct tape in her hair that matched duct tape recovered at another point of interest in the investigation, Keller Lake, in Maplewood, Minn., which is less than two miles from where Trevino lived in St. Paul.
Through the evidence collected, the medical examiner determined that Trevino was likely murdered in an extremely violent manner, according to the station.
Trevino went missing Feb. 21 after leaving her job at the Mall of America. Her husband, Jeffery Trevino, 39, remains locked in a jail cell charged with two counts of second-degree murder after large amounts of his wife's blood were found at the couple's home.
Jeffery Trevino is expected to appear in court later this month.
