Each year the Elsman girls went with family members on a trip, a vacation the two teenagers anticipated all year. On Thursday morning they were strolling the neon-trimmed heart of New York City when a motorist jumped the curb and plowed through three blocks of Times Square sidewalk and into crowds of pedestrians. Twenty people were injured, including 13-year-old Ava Elsman.
One person was killed: Ava’s sister, Alyssa, who was 18.
Alyssa was a delight to know but initially reserved, said Eric Alburtus, the principal of Central High School in Portage, Mich., the city of about 48,000 people where she grew up.
