"My heart died": Father of tourist killed in Times Square speaks out

The father of a young tourist who was killed when a man drove into a crowd in New York City's Times Square is speaking about the anguish of losing his first born child as another of his children is still hospitalized with severe injuries.

"Numb. There's no words. I want to scream," Thomas Elsman said in an exclusive interview with Fox 5 News on Friday. "My first born daughter is gone. My heart died in New York yesterday."

Alyssa Elsman, 18, of Portage, Michigan, was visiting the city with her younger sister Ava when tragedy hit. They had just landed hours before and had been in the Times Square area for just a matter of minutes, according to their father.

Alyssa and her 13-year-old sister where both on the sidewalk when the speeding car crashed into them and at least 20 others. One of Elsman's last social media posts was a video recorded about 10 minutes before the incident.

Ava Elsman underwent surgery on Friday. She suffered a fractured pelvis, broken leg and a collapsed lung. Her father says she knows about her older sister's death.

Elsman graduated from Portage Central High School in 2016. The school had counselors available to students on Friday.

Pedestrians chased and captured the driver as he tried to run away from the scene.

"If it was an accident I would forgive," Thomas Elsman says. "The fact that I found out he was on drugs, and then also today in court said 'I wanted to kill everyone' and he wanted to go suicide-by-cop, that's intent. He knew what he was doing and I don't care what happens to him."
