The parents of a British teenager killed in a crash involving a US diplomat’s wife came to New York to make a direct appeal on Monday, begging both President Trump and their son’s accused killer to “Just do the right thing.”

Charlotte Charles, 44, and Tim Dunn, 50, traveled to the US after almost two months of trying to get justice for their 19-year-old son, Harry Dunn, who Anne Sacoolas allegedly hit while driving on the wrong side of the road in August — before fleeing back to the US claiming diplomatic immunity.

“She needs to just do the right thing and just come back and face what she has done,” Charles said at a press conference in Manhattan Monday morning, adding that Sacoolas’ return would be the “only humane thing to do.”

“Face us as a broken family. Face our UK system and just do the right thing,” Charles said. “She needs to set an example to her own children that you can’t run away when you’ve done something so terribly wrong,” Charles said of Sacoolas, whose husband, Jonathan, is an intelligence officer at RAF Croughton.

The family said it also wanted to appeal to Trump, who said last week he would speak with Sacoolas to “see what we can come up with to do some healing.”

“We need him to agree to put her on a plane back to the UK,” Charles insisted.

Dunn, meanwhile, appealed directly to Trump “as a man, as a father.”

“If you were a father and your child died, surely you’d want that person to own up and take the responsibility of their actions,” he said. “That’s all we want.”

They stressed that Sacoolas, 42, had never needed to flee — because they were pushing for her to get reduced charges of death by careless driving to keep her out of jail on a suspended sentence.

Charles said they did not want to “take her away from her children — though she’s robbed us of one of ours.”

Their arrival stateside coincides with Sacoolas breaking her silence — saying she wanted to meet them to “express her deepest sympathies and apologies” for their son’s “tragic accident” in late August, allegedly while she was driving on the wrong side of the road.

Mom Charles called her statement “too little, too late” and broke down in tears when she spoke of how long it took to get an apology, which is still just in writing.

“We haven’t heard her voice. I don’t know how sincere it is,” she said.

The grieving parents, who are also meeting lawyers to consider legal action in the US, want to meet Sacoolas — but only back home.

“We’re not inhumane. We still don’t wish her any ill harm. But we need to hear it from her, in her own words, in a room, on our terms in the UK with therapists and whoever else around us that can help,” Charles said.

Earlier, they appeared on “CBS This Morning” where Dunn was overwhelmed telling Gayle King about the moment he got the call that his son was hurt — racing to the scene and seeing him for the last time.

“When I got there the paramedics were just putting him onto the stretcher and pulling him out of the grass verge,” the dad said, struggling to contain his emotions.

“I could see broken bones out of his arms — but he was talking. I called over to him and said, ‘Harry it’s your dad. They’re gonna fix ya. Be calm — let them help you.'”

He said it calmed his son’s moaning, and medics said they would sedate the teen to help his breathing.

“I told him, ‘It’s for the best, you’re gonna be OK.’ They sedated him and that was the last time I saw him,” he said.

Charles also said that the ongoing battle for justice has put the family’s grief “on hold.”

“You’re in pain from morning to night that no painkillers can take away,” she said. “You’re not able to cry because we can’t understand this whole situation as to why she would have left us.”

Sacoolas’s lawyer, Amy Jeffress, insists that the mom had “fully co-operated with the police” at the time of the crash and “will continue to co-operate with the investigation” by Northamptonshire police.
