Jeffery Trevino displayed an unusual calm in the aftermath of his wife's disappearance last winter and even referred to her in the past tense, according to witnesses who testified Thursday on the opening day of Trevino's murder trial.
That calm, according to prosecutors, masked an intense rage that Trevino harbored against his wife, Kira Steger, over her involvement with another man.
"The case you're about to hear is about rage," Assistant Ramsey County Attorney Andrew Johnson told jurors during opening statements. "It's about jealousy. It's about deception. It's about a cover-up.
"She wanted to leave, but he didn't want to let her go."
Trevino's attorney, John Conard, told the eight men and six women on the jury that the case against his client is built on circumstance and exaggerations about the evidence, including the authorities' claim that large amounts of blood were found in the couple's rented home in St. Paul.
"There is less than a thimble of [Kira Steger's] blood in the bedroom," Conard said. "That will become critical."
Details about Steger emerged as well, including a friend's testimony that girlfriends had become worried about her drinking and "staying out late," and that Steger was having an affair with a superior at work that she hid from close friends.
The case against Trevino, 39, began with the Feb. 22 disappearance of his wife, which led to intensive searches by police and volunteers who came from across the metro area. The searches continued through the late winter and spring until Steger's body was recovered from the Mississippi River on May 8. Trevino's arrest came well before his wife's remains were found, and he now stands charged with second-degree murder in Ramsey County District Court.
