According to an amended criminal complaint filed Tuesday against Jeffery Trevino, Kira Steger Trevino's purse that was left inside her parked car at the Mall of America contained divorce papers, the Star Tribune reports.
The Pioneer Press says the forms were left blank and appeared to have been downloaded from the Internet.
Also added to the court document, the Star Tribune reports, is that Steger Trevino texted a man she "had seen romantically" on Feb. 21, the day she was last seen. The man's address was later found written on something inside her husband's car.
The updated charges state that friends told police that Steger Trevino thought her husband had been following her.
The severely-beaten body of Steger Trevino, 30, was recovered from the Mississippi River last Thursday. The medical examiner ruled her death a homicide.
Trevino, 39, was charged in late February with second-degree murder based on the large amount of blood found in Steger Trevino’s car and at the home in St. Paul that couple shared.
Other evidence in the case includes a bag found in Keller Regional Park in Maplewood that contained clothes and a bloody pillow, matching Steger Trevino’s DNA.
The Pioneer Press also pointed out in the updated court document that Steger Trevino's driver's license was found by a resident cleaning up debris near his home in Vadnais Heights, about 4.5 miles away from the Trevino-Steger home.
The location is about a mile away from Walmart. Trevino showed investigators a Vadnais Heights Walmart receipt dated Feb. 23 at 12:16 p.m., showing he bought bread, milk and cleaning supplies, including Pine-Sol and Formula 409, according to the complaint.
The Ramsey County Attorney's Office has not said whether it will end the case to the grand jury for a possible first-degree murder indictment.
