TCSO Cold Case Task Force seeks contact information for victim’s families
Members of TCSO’s Cold Case Task Force are asking for the public’s help in locating family members for dozens of unsolved cases.
“Family members are essential”, says TCSO Spokesperson Casey Roebuck. “The families are the ones these investigators are working to find answers for.”
The task force is taking a closer look at 26 unsolved cases from across Tulsa County. While investigators are in close contact with some of the victim’s families, contact information for other families is no longer current. Some of these cases are more than 30 years old and some of the family members may be deceased.
It’s important that additional relatives are found who can provide DNA samples and information about their family member.
Families are asked to contact Doc Shannon by phone at (918) 596-5723

Task Force Background Information
In June of 2016, Sheriff Regalado created the TCSO Cold Case Task Force. The Cold Case Task Force has some of the most experienced homicide detectives in Northeast Oklahoma, and several other experts in their field. These highly skilled individuals are known nationally and internationally for their expertise in their field.
Each of the task force team members have volunteered their time and expertise to take a fresh look at the case files and prioritize them in terms of solvability. They are looking for evidence that could potentially be tested using new technology and witnesses that could be re-interviewed. Their hope is that they will be able to bring closure and justice for the victims’ families.
The unit focuses its resources on those cases with the highest probability of being solved with fresh leads and new forensic technologies. In many cases, biological evidence is still present allowing recent advances in DNA testing to bring those responsible to justice.
The truth about each case is out there; someone knows who committed the murder.
There are 26 cases that Sheriff Regalado asked the task force to review. Since the task force formation Task Force members have volunteered countless hours and have made progress in the Dean investigation as well as others. The most notable accomplishment was the identification of an unknown female’s remains that were discovered in rural Tulsa County in December of 1992, as Greta L Riles.
THE TCSO COLD CASE TASK FORCE MISSION STATEMENT:
“To speak for those who cannot speak for themselves by seeking answers and justice for victims and their families”.
