Case overview
Britney Cosby, 24, and Crystal Jackson, 24, were found shot to death in a parked car at Gabbard Park in southeast Houston on March 6, 2014. The investigation quickly focused on one suspect, but gaps in forensic evidence and conflicting witness accounts left critical questions unresolved even after an arrest was made.
The last known movements
On the evening of March 5, 2014, Cosby and Jackson left a gathering in the 9500 block of Scott Street in Houston. Both women were longtime friends and had spent the evening socializing before deciding to leave together. Witnesses reported seeing them depart in a white sedan shortly before midnight.
At approximately 10:40 a.m. the following morning, a passerby discovered the vehicle parked in a secluded area of Gabbard Park, located near Cullen Boulevard and Airport Boulevard. Both women were found inside the car, deceased from gunshot wounds. The vehicle’s engine was off, and there were no signs of a struggle outside the car.
Houston Police Department homicide investigators responded to the scene and began processing evidence. The location was not heavily trafficked, and no witnesses reported hearing gunshots during the overnight hours.
Early investigative focus
Detectives identified James Larry Cosby, Britney Cosby’s father, as a person of interest within days of the discovery. Investigators learned that James Cosby had objected to his daughter’s relationship with Jackson, and multiple sources indicated ongoing family tension.
On March 11, 2014, five days after the bodies were found, James Cosby was arrested and charged with two counts of capital murder. The Harris County District Attorney’s Office announced the charges publicly, describing the case as an investigation involving family conflict and targeted violence.
James Cosby was held without bond pending trial. The arrest drew significant media attention given the relationship between the suspect and one of the victims.
The evidence and its limits
Prosecutors built their case on witness testimony and circumstantial evidence. Several individuals told investigators that James Cosby had made threats regarding his daughter’s personal life and had expressed disapproval of her relationship with Jackson. Phone records and timeline reconstructions placed James Cosby in the general area during the hours leading up to the estimated time of death.
The physical evidence presented challenges. No murder weapon was recovered. Forensic testing on the victims’ vehicle yielded limited usable DNA or fingerprint evidence linking James Cosby directly to the scene. Ballistics analysis was conducted on shell casings found in and around the vehicle, but investigators were unable to match them to a specific firearm.
Witness statements varied in detail and consistency. Some accounts described James Cosby’s behavior in the days before the murders as erratic or hostile, while others provided alibis or alternative explanations for his movements.
The case collapses
In August 2014, the Harris County District Attorney’s Office announced that it would not proceed to trial. Prosecutors cited insufficient evidence to meet the burden of proof required for a capital murder conviction. The charges against James Cosby were dismissed, and he was released from custody.
The decision sparked public and media scrutiny. Advocates for the victims questioned whether the investigation had been thorough enough and whether additional forensic work or witness interviews could have strengthened the case. The Harris County District Attorney’s Office declined to provide detailed explanations for the dismissal, citing the ongoing nature of the investigation.
Houston Police Department officials indicated that the case remained open and that detectives would continue to pursue leads. No additional arrests have been made.
What remains unresolved
The murders of Britney Cosby and Crystal Jackson remain officially unsolved. The lack of a murder weapon, the absence of direct physical evidence tying any suspect to the crime scene, and the conflicting witness statements have left investigators without a clear path forward.
Family members of both victims have continued to call for accountability. In public statements, relatives described the women as close friends who had been targeted because of their relationship. Advocacy groups focused on violence against LGBTQ individuals have referenced the case as an example of the challenges faced in prosecuting hate-motivated crimes, though no hate crime charges were ever filed.
The case has also raised questions about the use of circumstantial evidence in capital murder prosecutions. Legal analysts have noted that the decision to arrest and charge James Cosby before securing stronger forensic evidence may have undermined the prosecution’s ability to build a viable case.
No new suspects have been publicly identified, and the investigation has generated limited updates since 2014. The Harris County District Attorney’s Office has not indicated whether the case is being actively worked or whether it has been classified as cold.
