A 17-year-old boy from Los Angeles who drove into a mother walking her baby in a stroller in 2021 — then was controversially handed a light sentence — was fatally shot in California Wednesday.

Kristopher Baca, who had not been publicly identified until his death because of his age, was gunned down in a driveway in Palmdale, a city 10 miles south of Lancaster, the Los Angeles County Sheriff’s Department confirmed with The Post.
