NEW YORK (CBSNewYork) – A Florida man visiting New York City for a wedding has died after being attacked over the weekend.

Sandor Szabo, 35, arrived in the city Saturday, but the celebration turned violent around 1 a.m. Sunday.

Police said he was punched in the face on 29th Street near 41st Avenue in Long Island City, Queens. The blow was so hard, Szabo fell backwards, hitting his head on the concrete.

His family said the marketing professional was leaving the hotel where his brother was staying and called for a car to go back to his own hotel. The family believes he was knocking on car windows to check on his ride when he knocked on the suspect’s window.

The man exited a white SUV and punched Szabo, leaving him bleeding on the ground. He was placed on life support and later died.

On Wednesday, the family sent a statement to CBS2 reading in part:

(Sandor’s) family and friends are overwhelmed, but not surprised, by the outpouring of love and support from the many people whose lives he touched; he did not know a stranger. He was kind, giving, loving and enjoyed life to the fullest. He will be missed but there is comfort knowing he will live on in the many lives he will save through organ donation with “Live On NY”.

The family, along with police, urge anyone with information to come forward.
