53-year-old Andrew Lukehart is scheduled to die by lethal injection tonight at 6pm ET for the murder of his girlfriend’s 5 month old daughter. Lukehart fractured the skull of baby Gabriella after losing his temper while changing her diaper.  Hear the fabricated story he told police, before eventually admitting his guilt. And, to make matters worse, Lukehart committed the brutal killing after recently being released from prison for beating his former girlfriend’s 8-month-old daughter just two years earlier.
