Three members of an Indian-origin family were killed in a car crash in the US state of Texas, leaving behind their 14-year-old son as the lone survivor, media reports said.

The deceased include Arvind Mani, 45, his wife Pradeepa Arvind, 40, and their 17-year-old daughter Andril Arvind, all residents of Leander.

They were killed around 5.45 am on Wednesday near Lampass County, local media reported.

Their 14-year-old son Adiryan who was not in the vehicle with them became the only surviving member of the family.

A GoFundMe page set up to financially aid the grieving boy has raised over $700,000.

According to reports, Arvind and his wife were driving their daughter to college in North Texas when they met with the fatal accident.

The 17-year-old girl had just graduated from high school and was going to attend the University of Dallas where she planned to study computer science.

Authorities said that the crash killed five people in total, including the driver of the car that crashed into the Indian-origin family's vehicle which then caught on fire.

"There was no chance of survival. It is one of the worst crashes I have seen in 26 years because of the magnitude of the damage and amount of people lost," police told local media.

Police suspect that the driver of the car that hit the family could have been driving at 160kmph based on a witness who said the vehicle zoomed past her.
