Kristina Ramirez, a U.S. citizen living in Chicago, says she was detained by U.S. Customs and Border Protection (CBP) in May for three days after she and her husband made a wrong turn in Michigan and ended up near the Canadian border.A CBP spokesperson told Newsweek in an email Friday evening: "CBP has no indication Mrs. Ramirez was held for 3 days. Her and her husband were referred to secondary for not having the proper U.S. travel documents on May 31," adding that "the assertions Mrs. Ramirez was held by CBP for 3 days are a bold face lie."Ramirez's husband, who is originally from Mexico, has been living in the Chicago area for two decades and has a pending U.S. visa application, according to local news stations ABC 7 and CBS News Chicago. He remains in custody and was transferred to a detention center.Newsweek reached out to Immigration and Customs Enforcement (ICE) via email and Ramirez via LinkedIn message for comment.Why It Matters Ramirez's detention and subsequent release come amid an immigration crackdown under the Trump administration, the president having pledged to launch the largest mass deportation operation in United States history.Immigrants residing in the country both illegally and legally, with valid documentation such as green cards and visas, as well as those with criminal histories, have been detained. Many with past convictions, even from decades ago, have found themselves in ICE custody despite spending years without facing serious immigration problems. Some U.S. citizens have reportedly been swept up in immigration efforts as well.What To Know Ramirez told local outlets that she and her husband, Sergio Serna Ramirez, were on a business trip in Michigan when they accidentally turned the wrong way and were stopped by CBP agents at the Canadian border.At a Wednesday community event calling for her husband's release, Ramirez said their lives "are being derailed because we took one wrong turn."On May 28, the couple was stopped by CBP and taken into custody. Ramirez, who is a U.S. citizen, says she was held for three days, while her husband was detained and then transferred to an ICE facility.According to the local outlets, he is currently held in a detention center at Monroe County Jail in Michigan. Ramirez said that CBP told them at the time of their detention that "we're going to let him out in 48 hours," ABC 7 reported....What People Are Saying A CBP spokesperson told Newsweek in an email Friday night: "After inspection and questioning, CBP determined Mr. Ramirez is removable from the United States under the Immigration and Nationality Act and was turned over to ICE. Mrs. Ramirez was subsequently admitted into the U.S. on June 1."Kristina Ramirez said on Wednesday: "My husband is not a murderer, my husband is not a criminal. My husband is a very loving and good person. I just am very upset, outraged by the injustice in this world. It just wrong how they have him there."Ed Yohnka, director of Communications and Public Policy for ACLU of Illinois, said during a community event on behalf of Sergio's release on Wednesday: "This is a human tragedy about one family but is also an example of system that has run amok."What Happens Next Ramirez is working with local community members to try to get her husband out of ICE custody. He is reportedly awaiting a final court hearing next week.Updated 8/23/25, 10:37 a.m. ET: This article has been updated with comment from the CBP.
