Sabrina Sparkman was a successful and highly regarded real estate agent who had made her home and career in the community around Possum Kingdom Lake, Texas. The 60-year-old female had lived full-time in The Hills Above Possum Kingdom Lake since January 2013 and was deeply involved in the local area. She was an active member of the Possum Kingdom Chamber of Commerce, the Mineral Wells Chamber of Commerce, the Mineral Wells Rotary Club, and the Palo Pinto Historical Association.
With a background in exercise and sport science and over 30 years of experience as a small business owner, Sabrina brought a high-energy, people-focused approach to her work. She became a licensed Texas Realtor in 2015 and earned her broker license in 2020, working as a Broker Associate with Coldwell Banker Realty. Her dedication earned her recognition as a Top Producer for Coldwell Banker from 2017 through 2024. Clients and colleagues knew her for her meticulous attention to detail and her commitment to making the process of buying or selling a home as seamless as possible. One of her favorite parts of the job was helping clients stage their homes to achieve the best possible sale price. She was married to Alan Sparkman.
A quiet Sunday morning was shattered by violence on September 27, 2026. At approximately 9:28 a.m., Sabrina's husband, Alan, made a frantic call to 911 to report that his wife had been shot at their home on Enchanted Rock Court in Graford, Palo Pinto County. When deputies from the Palo Pinto County Sheriff's Office arrived at the residence near Possum Kingdom Lake, they found Sabrina Sparkman deceased. An arrest affidavit later revealed she had suffered a fatal gunshot wound to her chest and was pronounced dead at the scene.
The Palo Pinto County Sheriff’s Office Criminal Investigation Division immediately began investigating the death as a homicide, calling in the Texas Rangers to assist. According to the sheriff's office, investigators utilized a combination of traditional methods and advanced resources to pursue leads in the case. They also received assistance from Sabrina's family and loved ones. Her husband told police he believed the shooting was connected to an ongoing and contentious custody dispute involving their grandchildren. He identified the children's parents as Jacob Henk and Kelsey Koger, and noted that Henk had access to firearms.
Investigators quickly focused on the couple. Using Flock license plate reading cameras near the Sparkman home, Texas Rangers identified a car registered to Koger in the area around the time of the murder. When questioned, Koger, who was reportedly separating from Henk, told authorities that she owned the vehicle but Henk had been using it. She cooperated with the investigation, allowing a search of her home and vehicles, where five guns were recovered. According to the arrest affidavit, Koger's brother told investigators that his sister had previously discussed killing Sabrina, and her mother had allegedly asked an attorney about the legal consequences "if Sabrina died."
Using a combination of surveillance video and cell phone data, authorities were able to connect Jacob Michael Henk, Sabrina's 34-year-old son, to the scene of the crime. On Thursday, October 1, 2026, just four days after the shooting, investigators with the Palo Pinto County Sheriff’s Office and the Texas Rangers executed a search warrant at a residence in the 6300 block of Claire Drive in Fort Worth. They located Henk at the home and took him into custody.
Jacob Michael Henk was arrested and booked into the Palo Pinto County Jail. He was charged with first-degree murder. Palo Pinto County jail records indicate he was also charged with assault causing bodily injury to a family member. Following his arrest, the sheriff's office stated that they had found no evidence to suggest any further threat to the public related to the case. As of October 2026, Henk remained in custody after being denied bond. The investigation was ongoing.
