A baby girl is dead after she and her pregnant mother were struck by a pickup truck Saturday night in North Amityville.

Police say Nancy Arevalo, 29, was crossing Route 110 at around 7 p.m. last night with her 10-month-old daughter Britney in a stroller when the two were hit by a pickup truck. Britney died a few hours later.

Arevalo suffered minor injuries, but was held for observation at the hospital because she is pregnant.

The pickup driver remained at the scene, but was not injured, according to police.
