Leka’s girlfriend Greta Luka said he shoved her to the ground and pushed his 9-year-old sister out of the way to save her when the black Dodge Charger jumped a curb, plowing into pedestrians on the sidewalk.

“I just remember the big black car coming towards us and then a big shove from him to push us over,” Luka told CBS2. “He definitely, definitely saved our lives.”
