DENVER (AP) — A former U.S. soldier accused of shooting and killing a transit guard in downtown Denver last month says he is a supporter of the Islamic State group, but investigators say they have not found evidence the terror group had anything to do with the killing. In a telephone interview Thursday from Denver's jail, Joshua Cummings told The Associated Press he pledged his allegiance to ISIS after spending three days behind bars fasting. Speaking calmly and addressing a reporter as "ma'am", the Islamic convert from Pampa, Texas, declined to discuss the crime or whether his support for ISIS led him, as police allege, to walk behind Scott Von Lanken while he was speaking to two women around 11 p.m.
