A Collin County jury convicted 65-year-old Donald Byron Joachim today of continuous sexual abuse of a child and handed down the legal equivalent of throwing away the key: life in prison with no chance of parole. Prosecutors said the abuse started when the victim was a toddler and continued through age 13, stretching across multiple Texas communities.
According to the Collin County Criminal District Attorney’s Office, Joachim, a Rosenberg resident, abused the child in Celina, Canyon Lake and Austin. The crimes came to law enforcement’s attention after the victim, at age 14, disclosed the abuse to her sister-in-law, and the Comal County Sheriff’s Office was notified. Assistant criminal district attorneys Pierce Richardson and Allison Barber tried the case, with support from District Attorney Investigator Greg Bowers and Victim Assistance Coordinator Melissa White.
"For too long, this predator exploited trust within families to abuse multiple children across years and locations," District Attorney Greg Willis wrote, according to the Collin County Criminal District Attorney's Office.
Judge and legal context
State District Judge Tom Nowak presided over the trial in the 366th District Court, according to the Collin County District Courts listing.
Under Texas law, continuous sexual abuse of a child is a first-degree felony that can bring a life sentence. Offenders convicted under Penal Code §21.02 also face special parole restrictions. Inmates serving sentences for that offense are generally ineligible for release under Texas Government Code §508.145, which helps explain why Joachim will not see a parole board.
How the case came to light
Prosecutors said the investigation began when the victim finally told a relative about the abuse at age 14, triggering a report to officials in Comal County. After that disclosure, multiple other children came forward and reported abuse that prosecutors said occurred in the late 1990s and early 2000s.
The Collin County jury ultimately found Joachim guilty of continuous sexual abuse of a child, then returned a punishment verdict of life in prison without the possibility of parole during the sentencing phase, according to the Collin County Criminal District Attorney's Office.
Collin County's approach to child-abuse cases
District Attorney Greg Willis and his office have a track record of pursuing long-running and historic child-abuse cases, pushing for lengthy or life sentences while emphasizing support for survivors. Previous press releases highlight similar prosecutions and detail how the team works with advocates and law enforcement. One example is outlined in a prior release from the Collin County District Attorney's Office.
In Joachim’s case, prosecutors have described the life-without-parole sentence as long-overdue accountability for a serial predator, reflecting years of investigation and painful testimony. The DA’s office publicly thanked investigators and victim-services staff for their work and urged anyone with information about similar crimes to contact law enforcement.
