BEAUMONT, TX — A 21-year-old Texas man has been sentenced to 34 years in prison for murdering a 16-year-old girl who was living with him after she became pregnant and he feared facing statutory rape charges.
Cody Arnold was found guilty of murdering Katelynn Stone in March 2022 at his home on Kolbs Corner near Beaumont, Texas. His co-defendant, Chelsea Shipp, who prosecutors said pulled the trigger, had previously accepted a plea deal and received 40 years for the killing. The case highlights the deadly consequences when fear of legal accountability drives violence against vulnerable victims.
The murder occurred on the weekend of March 26, 2022, after Stone took a pregnancy test that came back positive. Prosecutors said Shipp, who was about 25 years old and romantically involved with Arnold, told him “he was going to get in trouble for getting her pregnant” due to the age difference. Arnold worried he could be labeled a sex offender, and the pair hatched a deadly plan. “They were seen together. They were talking about what they were going to do,” Jimmy Hamm with the Jefferson County District Attorney’s Office said during Arnold’s trial. “They were smoking meth that entire weekend to build up the courage to kill that girl.”
According to Arnold’s account cited in a probable cause affidavit, around 2 p.m. on March 26, he walked into the room where Stone was sleeping and saw Shipp pointing a gun at her. The older woman then pulled the trigger, killing the teen. Arnold reportedly covered Stone’s head with a trash bag after the shooting, telling investigators he did so because he did not want to look at her. The Jefferson County Sheriff’s Office received a report of a “possible murder” at Arnold’s address around 5 p.m. on March 27, 2022. Deputies arrived to find Stone’s body with a gunshot wound.
Arnold was arrested immediately, while authorities secured a warrant for Shipp two days later. She was taken into custody on March 31, 2022. Witnesses told investigators that Shipp had been confessing to people she shot Stone, reportedly telling one woman “I got rid of her” and “I shot her” while using two fingers to make a shooting motion. According to The Beaumont Enterprise, Shipp told investigators that she killed Stone at Arnold’s request. When asked why she did it, she said, “Because one of them was sleeping around on the other.”
The case unfolded in Jefferson County, where prosecutors painted a picture of calculated violence driven by fear of criminal consequences. Stone had been living with Arnold at the time of her death, and the pregnancy represented what the defendants saw as a legal threat rather than new life. Texas law makes sexual contact between adults and minors under 17 a felony, with enhanced penalties when the age gap exceeds certain thresholds. The defendants’ alleged methamphetamine use over the weekend before the murder demonstrated premeditation rather than a spontaneous act of violence, prosecutors argued.
Arnold’s 34-year sentence reflects the severity of the crime and his role in the planning, though Shipp received a longer 40-year term as the actual shooter. The case proceeded through Jefferson County’s court system with Arnold initially maintaining his innocence before the evidence led to his conviction. Court records show the prosecution built their case on Arnold’s own statements to investigators, witness testimony about Shipp’s confessions, and physical evidence from the crime scene. The sentences ensure both defendants will spend decades behind bars for their roles in Stone’s death.
The Jefferson County community was shaken by the calculated nature of the crime, particularly the targeting of a pregnant teenager. Local law enforcement emphasized that the case demonstrated how fears of legal consequences can drive individuals to commit far more serious crimes. The investigation revealed the extent of the defendants’ planning and their callous attitude toward the victim, with Arnold’s decision to cover Stone’s face showing a disturbing detachment from the reality of their actions.
Both Arnold and Shipp are now serving their sentences in Texas state prison, with Arnold’s 34-year term and Shipp’s 40-year sentence representing substantial portions of their lives. The case stands as a stark reminder of the vulnerability of young people in exploitative relationships and the deadly consequences when adults choose violence over accountability.
