Mary Rose Trinidad, 55, of Teaneck, wiped away tears Friday as she spoke out for the first time since the tragedy.
"I'm dying inside over and over again. Justice will not bring them back, but we will be in a safer place," she said.
Trinidad and her family were inside a minivan traveling northbound on Route 1 on July 6 when a pickup truck traveling southbound crossed the median and struck the family's vehicle.
The crash killed her husband, 61-year-old Audie Trinidad, and her four daughters: 20-year-old Kaitlyn, 17-year-old Danna and 13-year-old twins Melissa and Allison. Ballocanag survived and was treated for serious injuries.
The driver of the pickup, 44-year-old Alvin Hubbard Jr., of East New Market, Maryland, was treated and released from the hospital with non-life-threatening injuries. He has not faced criminal charges, but an investigation is ongoing.
"Now that they're gone, I have nothing to look forward to but justice for them," Mary Rose Trinidad said.
Authorities indicated the investigation could last for months, said Diane Lucianna, the attorney representing Mary Rose Trinidad.
"We want to push this case forward as quickly as possible. We really feel the man should be in handcuffs behind bars. He's not. We're hoping that happens soon," Lucianna said.
A GoFundMe page was set up to support Mary Rose Trinidad.
Another vehicle, driven by Brian Kern of Bethlehem, Pa., was also hit by Hubbard's truck. He survived, and told Action News in an interview this month that the accident site "looked like a war scene."
