COPIAGUE - Family and friends are searching for answers after two teenage girls were struck and killed by a Long Island Rail Road (LIRR) train in Copiague last night.

Metropolitan Transportation Authority police say 18-year-olds Ariana Napolitano and Katherine Sanchez were hit by an eastbound train at around 6:30 p.m. just west of the train station.

Authorities say the two girls were standing on elevated tracks above an embankment, but they don't know how they got there and why they were there in the first place.

While investigators are not ruling out suicide, loved ones say there's no way the two teens would have wanted to die.

Family friend Debbie Rosselli says Sanchez, who planned to attend culinary school, was afraid of the tracks.

Napolitano and Sanchez graduated from Copiague High School last year. School officials say grief counseling will be available for students throughout this week.
