Gayle owns the distinction of returning the shortest punt for a touchdown in NFL history, when he returned a punt five yards for a touchdown against the New York Giants in the Bears 1985 divisional playoff victory. He is now appearing at the Chicago Bears Fan Convention. He currently works as a guest NFL analyst for Sky Sports in the United Kingdom.
Gayle was in a relationship with Rhoni Reuter, originally of Potosi, Wisconsin. On October 4, 2007, Reuter, who was approximately seven months pregnant with Gayle's child, was shot and killed at home, along with her unborn daughter.
On March 3, 2009, a Chicago woman, Marni Yang, 41, was arrested and charged with two counts of first-degree murder in the death of Rhoni Reuter at Reuter's Deerfield condominium. It is alleged that Yang was wearing a disguise when she shot and killed Reuter in a jealous rage. She was convicted of first-degree murder for this killing in March 2011.
The Deerfield police previously stated that they did not consider Gayle to be a suspect in the murder. They had sought a male teenager who was seen running from the area. Gayle had in the past complained that a former girlfriend of his had harassed Reuter and others, and had sought a restraining order against this woman. On October 4, before hearing of Reuter's death Gayle's attorney had filed a new complaint against this woman, claiming that the woman had violated the order.
