A Montgomery County jury has delivered a 45-year sentence to 23-year-old Devin James Alston for Continuous Sexual Abuse of a Child

CONROE, TX -- On Friday, September 19, 2025, in the 359th District Court, a Montgomery County jury found 23-year-old Devin James Alston guilty of Continuous Sexual Abuse of a Child and delivered a sentence of 45 years in the Texas Department of Criminal Justice (TDCJ). The trial began on September 12, 2025, with jury selection and testimony presented over the course of the week. The Honorable Judge Kathleen Hamilton presided over the trial. The case was prosecuted by Assistant District Attorney Tamara Tyler of the Montgomery County District Attorney’s Special Victims Division and Assistant District Attorney Mary Garcia.

The case involved two child victims, now 15 and 10 years old, who did not know each other. Both were just seven years old when the abuse began. One was related to the defendant, and the other was a child he regularly babysat.

The disclosure came after school staff discovered multiple concerning TikTok posts, made by one of the victims, that were clear indications of a cry for help. Staff promptly reported the posts to the Texas Department of Family and Protective Services, which initiated an investigation by the Houston Police Department. That investigation was later referred to Detective Michael Lee of the Montgomery County Sheriff’s Office after one victim disclosed abuse occurring within Montgomery County. During the course of the investigation, Detective Lee also identified another victim in Liberty County who had recently reported abuse by Alston.

The evidence presented at trial showed that Alston’s abuse spanned three counties — Harris, Montgomery, and Liberty. Testimony revealed that he carefully groomed the children, their families, and their communities, gaining trust and access while being described by many as “great with kids.” This reputation allowed his abuse to remain hidden for years.

During her closing argument, Assistant District Attorney Tamara Tyler told jurors: “The fear of this defendant will terrify each of these girls for the rest of their lives, because what he did doesn’t expire. They don’t have the luxury of a clock running out like a sentence will run out for him.”

The Montgomery County District Attorney’s Office extends its gratitude to the Montgomery County Sheriff’s Office, along with all partner agencies, for their tireless work in helping bring this case to justice.
