A judge ruled this morning that former Chicago Bear Shaun Gayle can be cross-examined about his sexual relationships with women, including Marni Yang, the mother of three on trial in the killing of Gayle’s pregnant girlfriend. Gayle, due to take the stand this morning in Lake County, can also be asked about his behavior on the morning on Oct. 4, 2007, the day Rhoni Reuter was found shot to death in her Deerfield apartment.
