The Lehigh County coroner's office on Tuesday identified the last victim of the fiery crash that two weeks ago killed five people on Route 222 in Upper Macungie Township as Marcos Cruz of Allentown.
DNA testing was used to positively identify Cruz, 57, of the 300 block of North Franklin Street, the coroner's office said.
Cruz was one of five carpoolers on their way home from work at a packaging company in Lower Macungie at 3:59 p.m. March 2 when their car ran into an oncoming tractor-trailer, police said.
In the collision on Route 222, a half-mile south of Grim Road, the car split in half and the truck toppled onto its driver's side. Both the car and truck caught fire, and truck fuel exploded several times.
All five in the car died. All were from Allentown.
On March 4, Rosa Lajara-Marine, 59, and Mercedes Silvestre Castillo, 34, were identified as crash victims using a match of their fingerprints.
On March 7, Jessegel Diaz-Hernandez, 19, and Barbara Bruno Rondon, 30, were identified in a comparison of dental records.
The collision happened at what is called the 222-100 split, a highway link that for a short distance carries northbound Route 100 traffic and southbound Route 222 traffic.
The car was on the Route 100 side when, for reasons yet unexplained, it crossed the grassy median and slammed head-on into the tractor-trailer on Route 222.
The trucker, Richard Eckrote Jr., 48, of Salisbury Township, survived with minor injuries.
The carpoolers worked for the Quality Packaging Services International plant on Industrial Park Way.
