A Baytown man who searched online whether it was legal to kill an undocumented immigrant was sentenced to 35 years in prison after pleading guilty to murdering his fiancé, 27-year-old Luis David Banos, in their shared apartment. Ty Vaughn entered his plea on Sept. 30, avoiding a trial where he faced a possible life sentence, and Harris County prosecutors had agreed to recommend the 35-year term in exchange.
According to the Houston Chronicle, District Judge Lance Long followed that recommendation when handing down the sentence. Banos was shot in the face with a rifle on Jan. 14, 2025, according to police, inside the couple's apartment in the 3500 block of Crosby Cedar Bayou, an identification confirmed by the Independent. Vaughn was arrested nearly two months later and held at the Harris County Jail while the case moved through the courts.
Banos, a native of Mexico born in Guerrero, came to the United States at age 10 and was a DACA recipient, per the Chronicle's reporting. He had graduated from Impact Early College High School and Lee College and was working as a manager at a local McDonald's franchise, while also pursuing art, details that Click2Houston shared in humanizing his life after the arrest. Vaughn and Banos had been together for four years and had sought a marriage license in 2024 that was never returned.
A Staged Suicide Scene Unravels
Investigators say Vaughn and Banos argued on the day of the shooting, and witnesses heard the argument followed by a gunshot. Vaughn returned to the apartment at about 4 a.m. in what police described as an intoxicated state, then called 911 around 5:30 a.m., telling responders he had found Banos dead and that his life was over.
But the scene told a different story. Banos was found lying on the floor with his arm touching a rifle, and a torn photograph of himself and Vaughn was found in another room. Detectives also found blood on a pillow away from where Banos' body was discovered. Police also recovered surveillance footage showing Vaughn returning to the apartment just after 4 a.m., after which he sent a text message to Banos at 4:30 a.m. asking “Babe? Babe why are you not texting back?!?!” before placing his 911 call an hour later, a timeline the Independent laid out from court records.
Searches That Pointed to Premeditation
Investigators say they found an electronic inquiry about the legality of killing an undocumented person, evidence prosecutors highlighted as central to showing premeditation. A Baytown police detective also noted in a search warrant affidavit that Vaughn repeatedly brought up Banos' immigration status unprompted during interviews, which the detective said suggested an attempt to “diminish or disparage” the victim's worth, according to the Houston Chronicle's earlier coverage of the case.
Vaughn is an Army veteran who served as a private first class from 2012 to 2018 with no deployments. Prosecutors noted during court proceedings that he was arrested during his military service for distributing pills but was never convicted, military records confirmed by an Army spokesperson showed.
What the Sentence Means in Practice
Under Texas Government Code § 508.145, people convicted of first-degree murder involving a deadly weapon must serve at least 50 percent of their actual calendar sentence without good-time credit before becoming eligible for parole. That means Vaughn's 35-year sentence carries a mandatory minimum of roughly 17.5 years behind bars before any parole review, according to the Law Office of Greg Tsioros.
Following Vaughn's arrest in March 2025, Baytown Police Chief John Stringer issued a statement about the investigation and arrest, while a separate department notice warned that domestic violence can escalate to deadly outcomes and directed residents to the department's Victim Services Unit and the National Domestic Violence Hotline, according to the Baytown Police Department.
The case sits within a grim statewide pattern. The Texas Council on Family Violence reported in October that 160 people died from intimate partner violence in Texas in 2025, including nine victims who identified as members of the LGBTQ+ community, per Business Wire. Harris County, where this case was prosecuted, consistently leads the state in such fatalities, recording 38 intimate partner homicide deaths in 2023 alone, according to data cited by HoustonTX.gov.
