A 78-year-old man was killed, while his 79-year-old wife was listed in serious but stable condition at the hospital.
Investigators determined that a white Ford Econoline van traveling west on New Dorp Lane had hit the couple. The vehicle sped away in the direction of Richmond and Amboy Roads.
Witnesses at the scene said the couple was going to Thanksgiving eve mass at Our Lady Queen of Peace Catholic Church.
They said the priest ran out of the church after the accident and delivered last rites.
Their names have not been released pending notification of family.
