At the August sentencing of MS-13 gang member Walter Javier Martinez, Nobles had hoped to find a sense of closure and peace over the loss of her 20-year-old Kayla Hamilton, but left the courthouse with a feeling of emptiness.

“I didn’t get the relief that I thought I would with him being sentenced because of the fact that she’s still gone,” Nobles said in a phone call with the Washington Examiner Friday. “Time doesn’t heal everything.”

On Tuesday, Nobles will visit Washington to appear before the House Judiciary Committee in a hearing titled “The Biden-Harris Border Crisis: Victim Perspectives.” Nobles has spoken out, even testified before Congress, about her daughter’s death since her rape and murder in July 2022.

This time, she is desperate for the illegal immigration crisis to stop to prevent another family from losing a loved one following the heartbreaking loss.

“This has to stop. These are violent, violent, violent criminals who are coming here and they don’t discriminate against anybody, meaning they don’t care if you’re a Republican or you’re a Democrat,” said Nobles of Norfolk, Virginia. “They will hurt anybody. Everybody is at risk.”

Hamilton and her boyfriend moved from Norfolk to Aberdeen, Maryland, in 2021. The two had rented a room in a three-bedroom mobile home in a park called “Rancho” in Aberdeen, a town of roughly 16,000 residents located between Washington and Philadelphia.

In the week before her death, Martinez moved into a vacant bedroom in the mobile home.

On July 27, 2022, Hamilton came home from an overnight shift at work and went to sleep in her bedroom as her boyfriend left for work. Her boyfriend discovered her deceased body when he returned from work that evening.

“The state attorney and even the judge said it was a very violent and brutal death,” Nobles said.

Martinez pleaded guilty and accepted a state prison sentence of 70 years on Aug. 22, waiving the need for a trial and presentation of evidence.

Details of Hamilton and Martinez’s encounter remain unknown, but Nobles said Martinez had entered her daughter and boyfriend’s space, where he took her down, used a phone cord to strangle her, and then raped her.

In a desperate plea for help, Hamilton had called her boyfriend during the assault, but the call went to voicemail, recording her final moments of life.

“He took her $6 and went to lunch and bought three packs of earrings at Target,” said Nobles.

Nobles said she did not understand why her daughter was targeted and said she had never had an encounter with Martinez in the five days that he had lived in the shared mobile home.

Investigators had brought in Martinez and the other housemates for questioning after her body was found, but did not have enough evidence at the time to hold him. Rather than turning the underage migrant over to the Department of Health and Human Services Office of Refugee Resettlement when authorities determined he was not living with his sponsor, Martinez was handed over to Maryland Child Protective Services and placed in a group setting with other children for months after his attack on Hamilton — something that the state and federal government should never have allowed to occur, Nobles said.

Martinez first entered the United States illegally in March 2022, months before killing Hamilton. He was apprehended by Border Patrol agents in Rio Grande City, Texas, where he identified as an unaccompanied minor.

U.S. Customs and Border Protection said in a statement in January 2023 that it screens and vets immigrants in custody, but has not been able to explain how an individual known to the Salvadoran government as a gang member was allowed into the country.

He was released by federal authorities to an adult sponsor in the United States, who later booted him out of the house, which led him to rent a cheap room in the Aberdeen trailer park, Aberdeen police said in January 2023.

Nobles has been unable in the two years since her daughter’s murder to get an answer on why the known MS-13 gang member was admitted at the border and not tracked within the U.S. despite being under state and federal childcare programs.

What’s more troubling, she said, was learning of his record.

“He pleaded guilty because of a letter that was intercepted at the jail that he wrote to a pastor in El Salvador saying that he has committed four murders and two rapes,” said Nobles. “In that letter, he was still giving props out to his gang, ‘I committed four murders.’”

At sentencing, Nobles read her victim impact statement and said Martinez was visibly annoyed by having to sit through the heartbroken mother’s statement.

“When I was giving my impact statement, he was huffing and puffing and making faces and the defense had to tell him, ‘Walter, hush,'” said Nobles.

Nobles hopes that with Martinez’s DNA, police can solve the other murders and sexual assaults that he confessed to in his letter.

Nobles said her daughter’s murder was at the beginning of what has been a noteworthy string of crimes targeting women and girls by illegal immigrant suspects. She has confided in Patty Morin, whose daughter Rachel was raped and murdered in the same Maryland county last year by a different illegal immigrant.

Martinez will face deportation proceedings once he has completed his prison sentence.
