Mindy Montford
Attorney Executive Director, National Cold Case Center |
Mindy Montford has spent 30 years working in the criminal justice system. She earned her undergraduate and law degrees from the University of Texas before beginning her legal career in Houston at the Harris County District Attorney’s Office, one of the largest in the country. She then returned to her hometown of Austin where she served as an Assistant District Attorney for ten years, handling felony crimes including sexual assault, child abuse, aggravated offenses, public integrity, domestic violence, and capital murder cases. While serving in the Travis County DA’s office, Mindy co-founded the prosecution internship program at the University of Texas School of Law and served as an Adjunct Professor teaching law students about the criminal justice system.
After leaving the DA’s Office in 2008, Mindy started her own law practice with a focus on criminal defense work. She was one of only a handful of female attorneys at the time selected to be on the “A-list” of attorneys who were qualified to represent indigent clients charged with the most serious felony offenses. In 2016, Mindy was asked to return to the Travis County DA’s Office to serve as the First Assistant District Attorney for the then-newly elected DA, Margaret Moore. In this role, Mindy managed an office of approximately 230 employees, including over 90 attorneys, with an annual budget of over $24 million dollars. As First Assistant, Mindy started a collaboration with the Austin Police Department Cold Case Unit, assigning prosecutors to work with detectives on cold cases from investigation through prosecution. During this time, Mindy started working on the widely known “Yogurt Shop Murders” investigation, which became a career highlight for her as she continued to work with law enforcement on the case for the next eight years until it was solved in 2025. In 2021, Mindy followed her passion for working cold cases and embarked on a new career path, starting a statewide cold case and missing persons unit in the Texas Attorney General’s Office. Mindy served as Senior Counsel for the unit assisting law enforcement agencies with their unsolved homicide investigations and overseeing the daily operations of the unit. During her time with the unit, Mindy developed standard operating procedures and protocols, coordinated roundtable case reviews with outside partner agencies, communicated regularly with forensic labs around the country to develop testing plans, designed annual statewide trainings, created a Retired Homicide Investigators Task Force, established an internship partnership program with Texas State University, and applied for and received state and federal grant funding for the unit. In just a short period of time, the unit has worked with dozens of local police departments to break open and solve multiple cold cases, including the highly publicized “Baby Holly” case that drew international attention in 2022 when the unit located Holly Miller alive and well 42 years after she went missing as an infant following the murders of her parents. Throughout her career, Mindy has tried over 100 jury trials, testified as a resource witness before legislative committees on criminal justice reform, and has helped draft key pieces of criminal justice legislation. She has presented as a lecturer on various criminal law topics at trainings and seminars and has appeared on news and radio shows as an analyst providing legal commentary on court cases. In early 2026, Mindy left the Texas Attorney General’s Office to start a non-profit organization designed to serve as a nationwide resource center for cold case investigations. She is expected to launch this new endeavor in mid-late 2026. |
