Authorities say three members of a Perth Amboy family heading to Niagara Falls were killed and six relatives were injured when an allegedly drunk driver's pickup truck hit their SUV in western New York.

Wyoming County Sheriff Gregory Rudolph says investigators believe the pickup ran a stop sign and hit the SUV around 6:30 a.m. Sunday in Sheldon. It's about 30 miles southeast of Buffalo.

Two women and a 4-year-old died. Six others, including four children, were taken to hospitals. The women were identified as 47-year-old Ondina Castro De La Cruz and 32-year-old Mayelin Brito-Castro.

Authorities say that the nine people were riding in a minivan made to hold only seven people. They say that the van did not have child safety or booster seats inside, and it is believed that many were not wearing seatbelts.

Twenty-year-old pickup driver Richard Sawicki was arrested on charges including aggravated vehicular homicide and DWI. He was arraigned and held on $200,000 bond.
