On Tuesday, jurors heard from Kathleen Rettke, a suburban wife and mother who testified she met Allan Kustok on an online dating site for married people.
They went to a downtown restaurant two days before Jeannie Kustock was shot to death in 2010.
Rettke told jurors she texted Kustok three times on the day Jeannie died.
Kustok claims his wife committed suicide.
