A Nicaraguan who entered under the Biden administration’s humanitarian parole program is currently facing two counts of second-degree sexual assault involving elderly victims at an assisted living facility in Wisconsin.
U.S. Immigration and Customs Enforcement also lodged an immigration detainer against the suspect, Julio Cesar Morales Jarquin, and the feds have urged Dane County, Wisconsin, officials keep him behind bars or turn him over to federal custody.
Morales Jarquin, 23, was working at an assisted living facility in Fitchburg, Wisconsin. Local police arrested him after receiving a tip on April 26 that an employee may have assaulted vulnerable residents and investigated the reports.
Dane County is home to Madison, Wisconsin. The U.S. Department of Homeland Security has described Dane County, Wisconsin, as a sanctuary jurisdiction and shared the county’s previous response on ICE detainers in a media release.
The feds brought attention to the case and called on local officials to “NOT release this criminal from jail back onto the streets to commit more crimes.”
“Due to sanctuary policies, Dane County officials often refuse to honor detainers or give ICE less than 30-minute notification before releasing criminal illegal aliens,” ICE shared on social media. “When local law enforcement honors ICE detainers, everyone is safer.”
ICE lodged a detainer asking Dane County, Wisconsin, not release Julio Cesar Morales Jarquin, an illegal alien from Nicaragua, who is currently facing two counts of second-degree sexual assault involving elderly victims.

Based on jail records, he remained in the county jail as of Monday. Court documents list him as Caucasian and living in an apartment on Pike Drive in Fitchburg.
Morales Jarquin was formally charged on April 29 following an investigation by Fitchburg police detectives, WKOW 27 News reported.
“The Fitchburg Police Department is committed to maintaining the safety of vulnerable members of our community and is working with the facility’s administration and protective services to ensure the well-being of all the facility’s residents,” police said in a statement shared to Facebook.
The department declined to release more details about the victims or allegations due to the ongoing investigation and sensitive nature of the case and did not mention the suspect’s immigration status.
DHS confirmed Morales Jarquin is in the country illegally, prompting the ICE immigration hold on April 27.
Morales Jarquin had his bond set at $200,000 during his initial appearance following formal charges being filed. A court commissioner ordered that he not have any contact with the victims.
According to court documents and local outlet WMTV 15 News, the defendant did appear in court with a translator on Wednesday, May 6, but another hearing was set for 3 p.m. May 13—meaning he could be released if he meets bail conditions.
DHS said Morales Jarquin was released into the United States in 2023 under the Biden administration’s humanitarian parole program for Nicaragua. The Trump administration ended the parole program in April of 2025, which also terminated his legal status.
Morales Jarquin remained in the U.S. illegally since that time. It is unclear when he found employment as a caregiver working with elderly patients.
“This dirtbag was released into the country by the Biden Administration,” said Acting Assistant Secretary Lauren Bis. “We need Wisconsin sanctuary politicians to cooperate with us to remove criminals from our country.”
Two other disturbing cases involving illegal immigrants from Nicaragua living in Wisconsin have made headlines in recent months.
Sevilla Benavidez left his mother with life-threatening injuries after allegedly stabbing her more than two dozen times. He reportedly became violent after she told him to turn down his music and attacked her in their home in Fond du Lac, Wisconsin.
He faces three counts for attempted first-degree intentional homicide, mayhem and aggravated battery in connection with the March 21 stabbing. All three charges include domestic abuse and dangerous weapon enhancers.
In a separate domestic violence assault, David Joel Mairena-Garcia, 29, was charged for a brutal machete attack that seriously injured his ex-girlfriend and another man.
Mairena-Garcia faces six counts, including two charges of attempted first-degree intentional homicide in the edged weapon attack in Green Bay, Wisconsin. He also has an immigration detainer hold and reportedly told police he became enraged and “just wanted to kill them.”
Earlier this year, DHS estimated 8% of Nicaragua’s entire population illegally entered the U.S. or came in through a humanitarian program under President Joe Biden. Cuba, Haiti and Honduras saw massive percentages of their populations cross the border during his term.
