Marcus Maddox, 30, is accused of fatally stabbing his 12-year-old daughter and leaving his 15-year-old son for dead. Authorities say he then drove across the valley and attempted to kill his wife and himself. An officer climbed through a window and found Tishia Maddox face down on a bed at Siegel Suites on East Craig Road. She had a severe wound to her forehead. When police arrived, they found Marcus Maddox with a gunshot wound to his head. Officials found the couple’s children in a Budget Suites room more than 17 hours later. Marcus and Tishia Maddox and their son remain in critical condition at University Medical Center.
