Immigration and Customs Enforcement (ICE) agents have arrested a 52-year-old Mexican national living illegally in the U.S. who is accused of decapitating a missing Illinois woman and concealing her body in a bleach-filled storage container.

Jose Luis Mendoza-Gonzalez, a resident of Waukegan, Illinois, was originally taken into custody in April and charged with concealing a corpse, abuse of a corpse, and obstruction of justice, according to the Department of Homeland Security (DHS). The charges stem from the disappearance and murder of 37-year-old Megan Bos, who had been reported missing in March but is believed to have vanished in February.

Despite the disturbing nature of the allegations, Lake County Judge Randie Bruno ordered Mendoza-Gonzalez’s release following his initial court appearance. He was freed under provisions of Illinois’ SAFE-T Act, which limits pretrial detention for certain offenses.

Mendoza-Gonzalez was re-arrested this past Saturday by ICE agents at a market in Chicago and is now in ICE custody, DHS confirmed.

Authorities discovered Bos’s remains in a container located on Mendoza-Gonzalez’s property. DHS officials said the body had been decapitated and found in a storage bin filled with bleach. According to Fox News, he is accused of keeping the woman’s remains on his property for nearly two months and abusing her corpse.

DHS condemned the judge’s decision to release Mendoza-Gonzalez. “It is absolutely repulsive this monster walked free on Illinois’ streets after allegedly committing such a heinous crime,” a DHS spokesperson told Fox News. “Megan Bos and her family will have justice.”

The incident has sparked outrage among local officials and lawmakers. Antioch Mayor Scott Gartner criticized the legal system that allowed Mendoza-Gonzalez to walk free. “I was shocked to find out literally the next day that the person that they had arrested for this had been released from prison under the SAFE-T Act… detained less, I think, than 48 hours,” he said, as reported by FOX 32 Chicago. He added, “There’s other extenuating circumstances in this case. Not only the type of crime, how long the crime was concealed, the fact that the person that was arrested for this is not a U.S. citizen, and, you know, can maybe \[flee] the country.”

State Representative Tom Weber (R) also voiced strong concerns over the release, stating: “Someone that hid their body in a garbage can for 51 days after leaving it in the basement for two days, after not calling 911 \[and] breaking a phone. Is this a non-detainable offense? Should we not find out, wait for a toxicology report, anything?”

The case has reignited the national debate over immigration enforcement and “sanctuary” policies. ICE Acting Director Todd Lyons, in a recent interview with CBS News, stated his agency remains committed to arresting anyone found to be in the country illegally, including those without criminal records.

“What’s, again, frustrating for me is the fact that we would love to focus on these criminal aliens that are inside a jail facility,” Lyons told Face the Nation host Margaret Brennan. “A local law enforcement agency, state agency, already deemed that person a public safety threat and arrested them, and they’re in detention.”

“I’d much rather focus all of our limited resources on that to take them into custody, but we do have to go out into the community and make those arrests, and that’s where you are seeing (that) increase” in so-called collateral arrests, he explained.

Lyons emphasized that ICE will not hesitate to detain individuals who are unlawfully present, even if they have no known criminal record. “If ICE encounters someone that is here in the country illegally, we will take them into custody,” he said.
