Middlesex County's prosecutor says the crash occurred on Old Bridge Turnpike around 7:30 p.m. Sunday. The preliminary investigation revealed the collision involved the emergency vehicle and a vehicle which contained a South River couple.
The husband and wife were pronounced dead at a hospital. Their names are being withheld until relatives have been notified.
The prosecutor's office says the East Brunswick Police Department did not notify it about the crash in a timely matter and the office is investigating the circumstances.
