Three members of a New Jersey family — including a 4-year-old girl — were killed early Sunday in upstate New York when an alleged drunk driver struck their SUV as they headed to Niagara Falls, according to authorities.

The fatal crash happened about 6:30 a.m. in Sheldon, NY, when Richard Sawicki, 20, allegedly blew a stop sign and plowed into the family’s vehicle on Route 20A, local authorities said.

Two women were ejected from the SUV and pronounced dead on scene. Six other family members inside the vehicle, including four children, were hospitalized.

Authorities didn’t immediately identify the victims.

Sawicki was arrested on scene and charged with aggravated vehicular homicide and DWI.

He was arraigned later Sunday and held on $200,000 bond.
