CHICAGO (WLS) — Sergio Serna Ramirez and his wife Kristina were on a business trip in Michigan back in May.

The couple said they took an accidental wrong turn that took them down a path that has since divided their family.

Now, a Chicago-area family is desperately trying to get a husband and stepfather, who they say was detained by ICE, back home.

“We have followed every law, we have jumped through every hoop and our lives are being derailed because we took one wrong turn,” Kristina Ramirez said.

On May 28, Sergio Serna Ramirez and his wife Kristina were in Michigan checking in on construction jobs, as part of the couple’s small business. A wrong turn took them near Canada, where they say U.S. Customs Border Patrol detained both Sergio and Kristina, who is a U.S. Citizen. She was released after three days.

“When we were detained, my husband, they said, ‘oh we’re going to let him out in 48 hours,'” she said.

But nearly three months later, she says her husband still remains in a detention center at the Monroe County Jail near Detroit.

“My husband is not a murderer, my husband is not a criminal. My husband is a very loving and good person,” Kristina Ramirez said. “I just am very upset, outraged by the injustice in this world. It just wrong how they have him there.”

Sergio’s family says he’s been a Chicago-area resident for two decades and currently has a pending U Visa application, in addition to being eligible for permanent residency through his wife. On Wednesday, his family and community leaders demanded he be released on humanitarian parole.

“This is a human tragedy about one family but is also an example of system that has run amok,” said Ed Yohnka, Director of Communications and Public Policy for ACLU of Illinois.

“We’re here demanding his immediate release because his detention is unjust,” Ald. Byron Sigcho-Lopez said.

Kristina says the past few months have taken on toll on their family, but not their determination to fight to bring him home.

“Without him, I’m heartbroken. I’m torn,” she said. “It’s just totally unfair, not right.”

Sergio’s attorney says he is awaiting a final court hearing next week that could end in an order of removal.

ABC7 Chicago has reached out to U.S. Immigrations Customs Enforcement around Sergio Serna Ramirez’s case, and they have not responded to the request.
