A heartbroken Wisconsin father says he can't forgive the 10-year-old girl accused of stomping on his baby boy's head. Nate Liedl is speaking out for the first time since the death of his 6-month-old son Jaxon. “As opposed to seeing it as a 10-year-old girl, I see it as the person who killed my son. She deserved to be in handcuffs. She's a criminal,” he told KTRK in an interview published Monday. The 10-year-old appeared in court, charged with first-degree murder as an adult.
