Mary Rose Trinidad sat at a table among her lawyers and family members Friday at the rehabilitation center where she's recovering from the wrong-way crash in Delaware three weeks ago that killed her husband and four daughters as they headed back to New Jersey from vacation.

They were there to announce that they want Delaware authorities to step up the investigation and criminally charge the driver they say caused the crash. And, they said, there will be a civil suit against him, too.

But before all that, Trinidad read a statement, and opened up about her pain.

"As you all know I lost my family (by a man who crossed over and drove in the wrong direction) and he's still walking free, and I have to bury my husband and four daughters."

She lost her husband Audie Trinidad, 61, and their daughters, Kaitlyn, 20, Danna, 17 and 13-year-old twins Allison and Melissa. They lived in Teaneck.

"I want justice for them. I want to see him criminally prosecuted," Trinidad said, emotion coming over her.

"All my broken bones and injures will heal, but not the unbearable pain in my heart," she went on.

"When they died, a part of me died. And I am dying inside over and over again."

"Justice will not bring them back, but we will be in a safer place,' Trinidad said.

She said she knows her husband is "with them, and he will take good care of my girls."

"I miss them so much," she said.

Her lawyers, Diane M. Lucianna and Frank V. Carbonetti, said they represent Trinidad's interests in seeing the driver charged, and they will sue him, too.

The driver, Alvin S. Hubbard Jr., 44, of East New Market, Maryland, was driving a Ford F-350 when he crossed over a grassy median on Route 1 in Delaware on the afternoon of July 6 and side-swiped another car before slamming into the Trinidad's Toyota Sienna.

To date, no criminal charges have been brought against Hubbard, and they believe what he did, crossing over from the south to northbound lanes, was a criminal act.

"Not one charge has been filed, not even a motor-vehicle charge has been filed, and to us it's been very upsetting," Carbonetti said.

Hubbard should be behind bars, Lucianna said. "In New Jersey, the man would have been taken away in handcuffs."

But the case is in Delaware, and the lawyers did say the Delaware State Police and that state's attorney general's office have pledged a comprehensive, full investigation and they understand it's a complicated, serious matter.

"We want to push this case forward as soon as possible," Lucianna said.

The Delaware State Police said they are on it.

"I can assure you that it is active and ongoing, and we'll be working with our attorney general's office on charges being filed," spokeswoman Master Corporal Melissa Jaffe said.

Trinidad's lawyers also said Friday that a passenger in Hubbard's vehicle reported to investigators that Hubbard may have been unresponsive, did not feel good and was coughing.

Nevertheless, it's criminal, Lucianna said. "There's no way its legal what he did, he crossed a 60-foot wide grassy median," she said.

Lucianna and Carbonetti said they will also be investigating Hubbard's employer, a metal works company, since he was driving a company vehicle and if Delaware should have had guardrails on the stretch of road.

Shortly after the crash, the Delaware Department of Transportation said on Twitter it was currently installing barriers along the Route 1, but hadn't yet done so on the stretch of road where the crash occurred.

Meanwhile, Trinidad is recovering from a broken left arm, two fractured knees, breaks to her ribs and a shoulder, and her right hip. But she's progressing.

Again, she said her bones will heal, but she's unsure she will ever work as a nurse again.

Her only mission, she said: "I am going to get better and seek justice for my family."
