Court records obtained by WCTV Monday revealed that U.S. Immigration and Customs Enforcement issued an immigration detainer for Olla-Hernandez, indicating that ICE plans to detain the suspect.
Furthermore, the documents state he is a citizen of El Salvador and identify him as “a member of a designated foreign terrorist organization” or “otherwise poses a risk to national security, border security or public safety.”
An ICE spokesperson said Olla-Hernandez illegally entered the U.S. near Hidalgo, Texas and was ordered to be removed by a judge in 2024.
“He has been identified as a suspected member of the Maravilla Salva Trucha gang (MS-13), a designated foreign terror organization as of 2025,” the ICE spokesperson said.
The detainer says Olla-Hernandez is a “removable individual” based on ongoing removal proceedings against him.

WCTV obtained Olla-Hernandez’s arrest papers Monday afternoon, which included additional details about the incident that began Thursday night into Friday.
According to the court records, he allegedly shot and killed Devin Graves, just before burning Graves’ body with the help of his girlfriend.
The probable cause affidavit indicated that the murder occurred in the 200 block of Pond Pine Street, where authorities said the suspect lived in a converted shed.
Olla-Hernandez suspected that Graves was involved with his girlfriend, which detectives said led him to lure Graves to his property.
The suspect allegedly shot Graves multiple times after he entered his shed, according to arrest papers.
The court papers went on to say that Olla-Hernandez forced his girlfriend at gunpoint to help clean up and dispose of Graves’ body, including burning the remains on the property.
“Look what you made me do,” Olla-Hernandez allegedly said just before pointing a gun at his girlfriend.
Forensic evidence included human remains found on Saturday in a fresh burn pile at Olla-Hernandez’s property, according to the affidavit.
Olla-Hernandez appeared in court Monday morning, where he was ordered to be held without bond. He was also ordered not to have any contact with his partner or the victim’s family.
A member of Graves’s family told WCTV Monday afternoon that his loss was shocking.
“Everyone involved needs to be held accountable and we just need justice for Devin,” she said.
The investigation is active and ongoing.
