MINNEAPOLIS (AP) - A prosecutor says a St. Paul man accused of killing his wife and dumping her body in the Mississippi River was driven by a jealous rage.

Jurors heard closing arguments Tuesday in the murder trial of Jeffery Trevino. Trevino is accused of killing his wife, 30-year-old Kira Steger. Steger was last seen alive on Feb. 21. Her body was recovered from the river in May.

Prosecutor Richard Dusterhoft argued Trevino was fed up with Steger texting a co-worker with whom she was having an affair.

Dusterhoft says the couple's marriage was "in deep trouble," and that Steger was cheating on Trevino. The prosecutor says, "That's a powerful motive."

Defense attorney John Conard continued poking holes in the presumptive blood tests and DNA results.
