The Harris County Sheriff's Office paused on Thursday to mark a painful anniversary, honoring Detective John Hampton Coddou III with a brief but pointed tribute to his "dedication, courage & service." Two years after he was struck and killed while responding to a crash on the Grand Parkway on April 23, 2024, friends, colleagues and local organizations are still holding up the 20-year HCSO veteran as the kind of deputy who pulled over to help a motorist simply because it was the right thing to do.
In an April 23, 2026 post, the Harris County Sheriff's Office remembered Coddou's end of watch. As reported by AP News, Sheriff Ed Gonzalez said, "Our hearts are broken, our spirits are crushed." Fellow deputies have repeatedly said Coddou's decision to stop and lend a hand that morning was exactly in line with the way he had served the county throughout his career.

Crash details
On the morning of April 23, 2024, Coddou had pulled onto the left shoulder of State Highway 99, the Grand Parkway, near Cumberland Ridge Drive to assist at what authorities described as a minor collision. Another vehicle veered onto the median and struck him, according to the Houston Chronicle. He was airlifted to Memorial Hermann–Texas Medical Center, where he was later pronounced dead. Sheriff Gonzalez and other deputies have said Coddou was the kind of officer who would stop to help even when the call was not assigned to him.
Investigation and legal status
New details released by the sheriff's office and reported by Click2Houston indicate the pickup driver who hit Coddou was reportedly talking on a phone and made what investigators called a "faulty evasive action" before driving onto the median and striking the detective. HCSO's Vehicular Crimes division took over the case, and the driver stayed at the scene. Investigators later identified that person as a suspect, although prosecutors had not immediately filed charges, according to AP News.
Remembering Coddou
Colleagues, family members and community leaders gathered for a May 1, 2024 funeral service at Second Baptist Church, followed by ongoing memorials in the months since, as Houston Public Media reported. The 100 Club and other charitable groups recorded Coddou's end of watch and shared survivor-fund information to support his family. Fellow deputies and local organizations continue to point to his military background and two decades with HCSO when they talk about his legacy.
A local reminder
Officials say Coddou's death remains a stark reminder of the risks first responders face when they step out on high-speed roadways. They have urged drivers to follow Texas' Move Over/Slow Down law whenever any vehicle is stopped on the shoulder. Local coverage has repeatedly framed the incident as both a warning for motorists and a plea to protect those who stop to render aid, including reporting from Click2Houston.
