ICE has lodged a detainer for Ulises Raigoza-Martinez, setting up a transfer that could send him into removal proceedings after prison.

Quick Take

ICE says it wants custody of Raigoza-Martinez after his sentence ends.
Officials say he is a Mexican citizen who entered the United States illegally through Texas in 2021.
He pleaded guilty on July 22, 2026, and received a 20-year prison sentence.
The case has drawn fresh attention to how immigration detainers work after criminal convictions.

ICE Moves to Secure Custody After Sentencing

The Department of Homeland Security says Immigration and Customs Enforcement lodged an immigration detainer against Raigoza-Martinez after his guilty plea and sentencing. The request tells Tennessee officials to notify the agency before his release, so federal officers can take him into custody for removal proceedings. Reporting says ICE believes he is removable because he is a Mexican citizen who entered the country illegally through Texas in 2021.

The criminal case began with a June 19, 2024, encounter in the parking lot of Nashville restaurant Smokin’ Thighs, where investigators say Raigoza-Martinez tried to steal tools from owner Matt Carney’s pickup truck. Police later arrested him in South Nashville on July 18, 2024, and the case moved through court before his July 22, 2026 plea. He pleaded guilty to murder, theft over $10,000, tampering with evidence, and theft over $2,500.

How the Detainer Process Works

An immigration detainer is a request, not a prison sentence or new criminal charge. It asks local officials to hold or alert Immigration and Customs Enforcement before release, which can allow federal custody to begin without another public arrest scene. Public guidance from United States government resources says people can be tracked through the online detainee locator using a name, country of birth, birth date, or an alien registration number.

That process matters because the public often sees only the courtroom result, not the immigration file behind it. In this case, the core facts are straightforward: state authorities handled the criminal case, and federal immigration officials now want custody when the sentence ends. For many readers, that raises the same common-sense question every time a violent offender is also in the country unlawfully: why should removal wait until after prison when deportation is part of the broader enforcement picture?

Why This Case Is Drawing Attention

Coverage of the case has focused on both the victim and the immigration status allegations tied to the defendant. Local reporting also noted that he was later charged with criminal homicide and evidence tampering in the death of Matthew Carney. ICE has said in similar cases that it uses detainers to move people into immigration custody after local criminal proceedings end, which is exactly what it says it is doing here.

Ulises Raigoza-Martinez, a criminal illegal alien from Mexico, pled guilty to murder, theft, and tampering with evidence after he RAN OVER and KILLED restaurant owner Matt Carney in Nashville, Tennessee.

He should NEVER have been in our country to commit this heinous murder.… https://t.co/eY1qIbvnvJ pic.twitter.com/4VZSZpV9x9

The story fits a larger pattern that frustrates many Americans: repeated crimes, delayed enforcement, and a federal system that often acts only after the damage is done. Here, the government has already secured a prison sentence, and now ICE says it wants to finish the job by taking custody for removal proceedings. Supporters of stronger border enforcement will see that as basic order, not controversy.
