The Irish man who made international headlines by comparing his ICE detention to a "modern-day concentration camp" is expected back on Irish soil today — where his abandoned twin daughters and 18-year-old drug charges are waiting for him.

Séamus Culleton, 38, failed in his legal battle to stay in the United States and is being deported back to Ireland for the first time in nearly 17 years, according to Extra.ie.

But the homecoming won't be the triumphant return his supporters hoped for.

Abandoned twins speak out

Culleton left behind twin toddler daughters, Heather and Melissa Morrissey, in Kilkenny before fleeing to the US. The girls, now 18, have publicly stated they want their father to face the courts.

When a GoFundMe was set up to raise money for Culleton's legal fees — highlighting how his wife wanted him home "to see his babies" (referring to the couple's dogs) — one of the daughters couldn't stay silent.

Heather Morrissey commented that her father should "worry about the real children he has — and not about the dogs."

'You'll never see him again'

After speaking out, Heather received a chilling warning from someone known to her father.

She was told Culleton was "upset" and that her comments could "affect his Green Card application." When she called the situation "insulting," the person responded: "Well then, good luck seeing Séamus because they will keep him in. Is that what you want?"

Massachusetts lawyer offers to seize GoFundMe

A Massachusetts-born attorney is now offering his services to help the twins claim the $28,000 (€23,600) raised by the GoFundMe — as back payment for 18 years of child support their father never paid.

Marc Randazza, a First Amendment lawyer originally from Gloucester who now practices in Las Vegas, told Extra.ie he believes the money can be seized if it's still in GoFundMe's accounts.

"Who does that to young children like that? I just want to help young women out," Randazza said.

Drug charges still 'active'

Before leaving Ireland, Culleton was charged with possessing drugs with intent for sale or supply, possession of drugs for personal consumption, and obstructing a garda in the course of their duty.

He failed to appear at New Ross District Court in Co. Wexford and a bench warrant was issued — but never acted on because he had already fled the country.

Security sources told Extra.ie there's a "strong chance" Culleton could finally face those charges.

"There's no such thing as a charge expiring," a source explained. "The DPP has already decided he should face the courts. It's now in the hands of the gardaí."

'Concentration camp' claims

Last week, Culleton called RTÉ's Liveline show from the ICE facility in El Paso, Texas, comparing his detention to a "concentration camp" and describing conditions as "torture."

"I just want to get back to my wife. We were so desperate to start a family," he said — apparently unaware, or unconcerned, that he already has a family in Ireland.
