The trial for Jeffery Trevino, the St. Paul man accused of killing his wife, Kira Steger, resumed Monday. Jurors heard from Ryan Wendt, the man with whom Steger was having an affair. Wendt, Steger’s manager at Delia’s, testified that their friendship turned romantic about a month before she died. He said he knew she was married and their relationship was ending, though they didn’t discuss their relationships. Steger told him she was separating from Trevino.
