Carlos Ambriz-Estrada, Unlawful Reentry of a Removed Alien, Oklahoma 2025

A 53-year-old Mexican national who was found residing in Catoosa, Oklahoma, and was previously deported after killing his 38-day-old son has been sentenced to 24 months imprisonment for Unlawful Reentry of a Removed Alien.

Carlos Ambriz-Estrada was sentenced by U.S. District Judge Gregory K. Frizzell on 2025 for his role in re-entering the United States unlawfully, announced U.S. Attorney Clint Johnson.

In March 2025, the Fugitive Operations Team with Immigration Customs Enforcement began investigating Ambriz-Estrada due to his prior conviction of deliberate homicide in Montana and the possibility of him being present in the United States unlawfully.

Court records show that in 1994, Montana law enforcement was dispatched to the hospital to investigate apparent child abuse. Ambriz-Estrada and his wife brought their 36-day-old baby to the hospital for treatment. The detective spoke with a doctor who confirmed that the baby had five broken ribs, detached retinas in both eyes, swelling of the head, bruises on the neck and abdomen, consistent with strangulation. The doctor reported that they believed the baby was strangled and without oxygen for some time, likely causing severe brain damage.

When being interviewed, Ambriz-Estrada admitted that he was angry with his wife and took it out on the baby. While the baby was crying, he squeezed the child’s throat for 15 to 20 minutes, until the baby lost consciousness. Afterward, he put the baby in a crib. The baby woke up crying one hour later, and Ambriz-Estrada admitted to picking up the baby and shaking him. Ambriz-Estrada told detectives the baby's breathing was irregular and appeared to have a seizure.

After two days in intensive care, the baby had no brain activity and was declared brain dead at 38 days old.

Ambriz-Estrada was ordered to 40 years imprisonment and served 12 years after pleading guilty to deliberate homicide. He was deported and returned to the United States unlawfully sometime in 2020.

Ambriz-Estrada is expected to face removal proceedings following the sentence. He will remain in custody pending transfer to the U.S. Bureau of Prisons.

The case was investigated by Homeland Security Investigations, with Assistant U.S. Attorneys Ammon Brisolara and Augustus Forster prosecuting the case.
