A teenage girl was killed by a hit-and-run driver on Long Island while walking to get some grub after getting off work with her twin, according to police and friends.

The 17-year-old girl, Jenna Perez, had volunteered to work an extra shift Saturday night at the Five Guys Port Jefferson Station with her twin sister Jenelle, according to the restaurant owner.

The twins were heading to Taco Bell just before 9:30 p.m. when they crossed Nesconset Highway near Terryville Road where a driver barreled into Jenna Perez and took off.

Perez died at the scene, cops said.

“This shook everyone up here,” said restaurant owner Bill Gellert. “I’m bringing in a grief counselor to make sure everyone is OK.”
