Teen Helps Save Stepdad Having Massive Heart Attack

15-year-old Anthony Killinger saved his stepfather's life. Two weeks ago, Michael Reese suffered a massive heart attack. Mother, Jennifer, found Reese at the bottom of the stairs and called 911. Anthony checked for a pulse and found one. The 911 operator said CPR needed to be performed, and Anthony got right to it. The teen tells Inside Edition he learned CPR in school in Buffalo, New York, after Buffalo Bills football star Demar Hamlin suffered cardiac arrest after a hard hit.
