Four members of the Army reserve continue to recover from their injuries after their Humvee on Thursday overturned on the New Jersey Turnpike.

State Police spokesman Captain Stephen Jones said it is still unknown what caused the Humvee to overturn in the southbound outer lanes south of Exit 9 in South Brunswick around 2:30 p.m.  Jones said it was part of a three-vehicle caravan that had crossed from the right lane to the center-left lane and back to the right lane where it struck a guard rail and overturned after the tire came off the vehicle.

The driver of the Humvee was identified as Gedry Concepcion-Munez, 29, of The Bronx. Another passenger, Deborah Perez, 25, of Brooklyn, suffered a severe leg injury and was taken via medical helicopter to Robert Wood Johnson University Hospital in New Brunswick.  A third passenger was Marcos Santana, 24, of Poughkeepsie, New York.

One passenger in the Humvee was from New Jersey: Theodore Jackson, 40, of Lincoln Park, is still in the hospital.

Both the inner and outer lanes were closed for over an hour causing delays of more than 10 miles before the road was reopened around 4 p.m.
