Suffolk County police said the siblings had been hit by a 2022 Chrysler Voyager which caused the three of them to be rushed to hospital.

The driver of the Chrysler, 44-year-old Francis Floyd, was not injured, nor were her two adult passengers, a 44-year-old woman and a 64-year-old man. 

Video captured by ABC7 shows the black vehicle with a side door open and several police officers on the scene.

No charges were announced by authorities, but the driver’s car was impounded for a safety check and the crash is under investigation. 

Kaydanov had been a member of the studio Dance With Us Long Island, and has been remembered as dedicated and gifted. 

Studio owner Stephanie Falciano told the New York Post: 'She was like a daughter to me and just the most incredible, beautiful creature inside and out.

'The hardest worker, smart, talented and beautiful. The world has lost today.'

Her grandmother, Lubov Kaydanov, told ABC7: 'I don't feel nothing. God has to take me, I am old. She is young.'

According to her website, Kaydanov worked in communications and was a recent graduate of Stony Brook University with an MBA in marketing.

On social media, friends began paying tribute to Kaydanov who was described as 'ambitious and kind'

Residents also told the outlet that they had frequently seen cars speeding on the car, which is not designed for pedestrians. 

It remains unclear at this stage if speeding was a factor in the fatal collision. 

Her brother Joseph is said to have sustained a broken leg and a broken collarbone and will require surgery, ABC7 reported.

One person posted: 'I am so devastated by this news. Ilona Kaydanov was extremely smart, talented, ambitious and kind. 

'She was my right hand woman at our last job and it wouldn’t have been the same without her. 

'I was always in awe of her academic and professional accomplishments at the young age of 20, and now at 22 and she had so much more to accomplish. 

'We went through a lot together in the short time we knew each other. You will be sorely missed, Ilona, and I will always cherish our bond.'

Another commented: 'Absolutely tragic… she is a beautiful soul that will be greatly missed. May god bless her and her family at this time.'
