4 stabbed to death, including 2 children, by relative outside burning Queens home

A crazed attacker fatally stabbed four relatives — including an 11-year-old girl and a 12-year-old boy — and then wounded two NYPD cops before they shot him to death outside his family’s burning Queens home on Sunday morning, according to police.

Cops raced to the home on Beach 22nd St. near Elk Drive in Far Rockaway at around 5:10 a.m. after a young girl called 911 to say her cousin was “killing her family members,” NYPD Chief of Department Jeffrey Maddrey said.
