Melissa LeSueur’s death became a documented Dallas cold case. Revisiting the investigation requires remembering her life—and distinguishing unanswered questions from unverified claims.
SEAGOVILLE — Melissa Kay LeSueur built a career in commercial property management, earned an associate degree from Tarrant County College and volunteered for the Dallas SPCA.
Her family’s obituary remembered her affection for animals, including her dog, Lucky.
Those details describe the person behind a homicide investigation that became part of the Dallas area’s cold-case history.
LeSueur, 35, was found shot to death in a field behind Seagoville High School on June 11, 2007. Despite the school’s name, the killing was investigated by Dallas police.
An October 2015 Dallas Morning News investigation documented the evidence detectives had pursued and the uncertainty her family continued to face.
According to that reporting, a friend told investigators she had been with LeSueur in the field the previous day before leaving to obtain insect repellent.
When the friend returned, LeSueur and her Chevrolet Blazer were gone. A police helicopter helped locate her body the following day.
Investigators also received information from a jogger who reported hearing gunshots and seeing someone leave in LeSueur’s vehicle.
The SUV was subsequently recovered after crashing into a house in Old East Dallas.
The newspaper reported that detectives questioned several people but lacked sufficient evidence to present a murder case to prosecutors.
At the time, the central questions remained unanswered: Who killed LeSueur, what prompted the shooting and what evidence could establish responsibility?
The sources reviewed for this article did not establish whether an arrest, prosecution or other resolution occurred after that reporting.
Her case can therefore be described as a documented historical cold case, with its current status requiring confirmation from Dallas police.
Her family’s obituary offers another way to remember her: as a college graduate, animal advocate, daughter, sister and friend whose life extended far beyond the circumstances of her death.
A separate Seagoville homicide illustrates why older reports must be checked against subsequent developments.
On Dec. 2, 2024, officers responded to a shooting at a community park in the 600 block of Fountain Drive.
The wounded man was found near a gazebo and later died at a hospital, according to a Seagoville Police Department release.
That initial announcement requested information and did not identify a suspect.
However, FOX 4 reported on March 10, 2025, that authorities had arrested a teenager facing capital murder and other charges in connection with the investigation.
An arrest does not establish guilt, and the sources reviewed here did not establish the final court outcome.
It does mean the original announcement cannot support describing the shooting today as a cold case with no identified suspect.
For residents revisiting older crimes, those distinctions matter. An unanswered question in an archived article is not proof that investigators never obtained an answer.
Anyone with information about LeSueur’s killing can contact the Dallas Police Department’s Crimes Against Persons Division at 214-671-3584 and ask to be directed to the investigator responsible for her case.
