Robertson's behavior in the hours following the shooting bothered Urlacher, according to the petition. Urlacher was with his son in Arizona just after 10 p.m. Dec. 29 when the boy received a Snapchat message from a cousin informing him that Karageorge had died. When Kennedy called his mother for confirmation she initially acted "happy and cheerful,'' Urlacher alleged, before she eventually claimed Karageorge was involved in a fatal car accident. The next morning, Robertson called Urlacher to explain that, in fact, Karageorge had shot himself after the couple had an argument and Willow Springs police confiscated her cellphone as part of the investigation into the death.
