A 6-year-old boy and his mother — who authorities said kidnapped the child — were found dead in a Texas parking garage, according to a report.

The boy’s father, John Wiedemann, who was estranged from mom Candace Harbin, reported the pair missing around 9 a.m. Friday, the Waxahachie Daily Light reported. Police in Waxahachie, a suburb of Dallas, sent out an Amber Alert, plus a kidnapping warrant for Harbin.

Nine hours later, cops discovered Phillip Oliver “Ollie” Weidemann and Harbin unresponsive inside the woman’s car.

Police are investigating how they died.
