Hero Down: Tarrant County Deputy Constable Mark Diebold Dies During Tactical Qualifications

Dallas, TX - Tarrant County Deputy Constable Mark Diebold, age 48, died on Thursday, September 8, of a medical condition that he experienced on the job.

Deputy Constable Diebold had just finished tactical qualifications when he appeared to have a heart attack, according to CBS DFW.  Tactical team members immediately started CPR, EMS arrived, and he was transported to Alliance Medical Center where he was pronounced dead.  The cause of death is still pending.

In July, 2016, Deputy Constable Diebold helped a couple deliver their baby at a north Texas gas station, an incident that he never forgot.  And in July, 2017, a photo of him celebrating the little girl’s first birthday at a tea party for two also went viral. Tiny teacups, flowers, and smiles were all captured in photos at Evelyn’s tea party.

He would often talk about the day Evelyn was born, when he stopped a black Jeep Cherokee as the driver sped past him.  Deputy Constable Diebold stopped the driver, Caleb Hall, and discovered Hall’s wife in labor.  He said, “All I could do was hold her hand and guide him on what to do.”

The baby’s birth moments later in a vehicle in the Quik Stop parking lot was captured on surveillance video.  Deputy Constable Diebold said, “Personally I needed it. That morning, I needed it more than ever. It was an answered prayer, literally. An answered prayer.”

From that day forward, he and his wife became friends with the family, and kept up with Evelyn as she went through her first year.

Tarrant County Sheriff Billy Waybourn said, “We are all one family. No matter what happens we have our brothers and sisters to rely on for support. No only to support each other, but to rise up and support Mark’s family. They need us more now than ever. Mark was an amazing person, and his light will be missed.”

Deputy Constable Diebold is survived by his wife and children.  He served with the Tarrant County Constable’s Office, and had previously served with the Tarrant County Sheriff’s Office for 14 years, according to Officer Down Memorial Page.

Our thoughts and prayers go out to the family of Tarrant County Deputy Constable Mark Diebold, both blood and blue. Godspeed, sir, we will take the watch from here.  Thank you for your service.
