MILLVILLE – Authorities are investigating whether alcohol played a role in a Saturday morning one-car crash that killed a local man and left three others in critical condition, Cumberland County Prosecutor Jennifer Webb-McRae said.

In a statement released today, Webb-McRae identified the deceased as 21-year-old David Rosado, who city police said was a passenger in the car.

Webb-McRae said the alleged driver of a car is a 17-year-old local resident who is listed in critical, but stable, condition. She would not identify the hospital were the youth is being treated.

Rosado’s brother, 19-year-old Brian Rosado, also of this city, is listed in critical condition at AtlantiCare Regional Medical Center in Atlantic City, according to Webb-McRae. Vineland resident Julio Lopez, 24, is listed in critical, but stable, condition at Cooper University Hospital in Camden, she said. Brian Rosado and Lopez were passengers in the car, she said.

While the investigation remains under investigation, Webb-McRae said in her statement that “the use of alcohol is being examined as a contributing factor” to the crash.

David Rosado was killed the others injured when their car struck a vacant building at South 2nd and Orange streets early Saturday, city police said.

Police said the car was traveling west on Orange Street at around 3:15 a.m. on Saturday. The car crossed the intersection at South 2nd Street, went into the driveway of a home in the 2000 block of South 2nd Street, and struck building’s southeast corner.
