OUR FIRST REPORT: Harris County Pct. 4 deputy accused of killing wife posed as mistress’ husband to adjust life insurance, records say
In the letter, Smith maintains his innocence, claiming that investigators verified evidence supporting his alibi but charged him anyway.
Smith, 39, is accused of murdering his wife, Laura Smith, 37, an elementary school educator with Lamar Consolidated ISD.
She was found dead on May 27, 2024, inside the couple’s home in the 6500 block of Snowbell Court in Richmond. Her death was ruled a homicide the following day, with court records stating she was stabbed with a sharp object.
Smith was charged with murder on Nov. 10, 2025, more than a year and a half after Laura’s death. He also faces a charge of fraud by possession of identification.
In the letter, Smith raises questions about another man whose blood he claims was found inside the home and describes an alleged incident involving a jail officer just days before he wrote the letter.
His bond is set at $500,000 for the murder charge and $7,500 for the fraud charge.
KPRC 2’s Michael Horton has submitted paperwork to the Fort Bend County Jail requesting to speak with Smith about the case.
Claims Made in the Letter
In the letter addressed “To Whom It May Concern,” Smith wrote that he was not involved in the killing of his wife and disputed public statements made about him by others, including Laura’s family.
“I would like to say that I had nothing to do with the murder of my wife, despite what others and her family has said about me through the media,” Smith wrote.
Smith claimed detectives verified his location at the suspected time of the killing, using GPS data from both his employer and his personal cellphone.
He wrote that he was working an extra job when his wife’s device pinged in another city, roughly 45 minutes away.
“If I had left that extra job or clocked out, my employer would have known, due to the GPS on the app I clock in on,” Smith wrote.
Smith also alleged that during sworn testimony on Dec. 1, 2025, a detective acknowledged that Smith’s DNA was not found on his wife’s body.
In addition, Smith claimed detectives testified that blood belonging to another man was found on a towel inside the couple’s home on the day of the murder. Smith described the man as someone his wife was having an affair with.
“At this point, I’m not worried about the other men,” Smith wrote. “I’m just worried about the man who’s [sic] blood was on a towel at my house and why isn’t he a suspect or charged, especially when it was verified my DNA wasn’t on my wife.”
Smith questioned why that man was never named a suspect or arrested, writing, “This doesn’t make any sense.”
Smith also pointed to the timing of his arrest, writing, “I was arrested a year and a half after my wife’s demise. Something is not right about this case.”
“My daughters need me and being locked up for a crime I didn’t commit is devastating to all of us,” Smith wrote, asking for help and urging officials to review the case.
Court records reviewed by KPRC 2 did not include documentation of the sworn testimony Smith referenced. KPRC 2 has not independently verified Smith’s claims regarding the alleged forensic evidence or testimony described in the letter.
Alleged Incident in Fort Bend County Jail Involving Officer
In the final portion of the letter, Smith alleged he was assaulted by a Fort Bend County Jail officer on Dec. 6, 2025.
Smith wrote that the officer pushed him and slammed a door in his face after Smith asked to speak with a supervisor. He said he was not aggressive or combative and that another inmate witnessed the incident.
Smith said he filed a complaint through the jail’s electronic kiosk system but had not received a response. He wrote that he fears retaliation against both him and the listed witness.
Smith wrote that if he had pushed the officer “the same way he pushed me, I would have been charged with a felony assault on an officer.”
KPRC 2 reached out to the Fort Bend County Sheriff’s Office regarding this situation. The office informed us that our request is being processed.
Background of the Investigation
According to court records obtained by KPRC 2, investigators were called to the Smith residence on May 27, 2024, after Laura’s sister requested a welfare check when Laura failed to respond to phone calls for around 12 hours.
Laura was found lying in bed, covered in blood, with a dumbbell weight on her left arm.
Later that day, LaMarcus voluntarily went to the Fort Bend County Sheriff’s Office to speak with investigators and was not under arrest at the time.
During the interview, Smith told investigators he had spent the night at the home of a woman he described as a “female friend” after leaving work on May 25. He later said that on the night of May 26, he briefly returned to his home but left again around 3:15 a.m. to report early for a second job. Smith also consented to a search of his phone.
Court records allege investigators later uncovered evidence of an extramarital affair, including matching tattoos, an engagement ring, extensive phone communications and life insurance activity involving the woman Smith described as a “female friend.”
Investigators also allege Smith impersonated the woman’s husband during a phone call with an insurance provider in an attempt to alter the husband’s life insurance policy. That allegation led to the fraud charge Smith now faces.
Additional allegations surfaced in 2025, including statements from family members claiming Smith attempted to solicit others to harm or kill his mistress’s husband — allegations detailed in court documents but not yet proven in court.
Smith remains in custody at the Fort Bend County Jail as the case proceeds through the court system.
