The former NFL star died of a heat stroke more than a month after he was found dead in his apartment, Frisco police told E! News on July 11. Police say Marion's death was an accident.
Officers were dispatched to Marion's home in June to conduct a welfare check. According to police, he was found dead at the age of 38 there.
"Really comforting to know he had that kind of support," Marion Barber II's father told the Fort Worth Star-Telegram when asked about the outpouring of tributes to his son after his death.
On July 2, Barber II told CNN, "I know it feels good to us to know that he was loved and respected that much." "The outpouring of support has been heartwarming. Those are the stories my family tells."
Over the course of his NFL career, Marion, aka "Marion the Barbarian," played for the Dallas Cowboys for six seasons, from 2005 to 2011. The Texas team reflected on their alum's legacy after his death.
Dallas Cowboys: "We're heartbroken by Marion Barber III's death." "Marion was a hard-nosed, old-school football player who won every down. His coaches and teammates loved him. We pray for Marion's family and friends."
Though he played for the Dallas Cowboys, Marion didn't play exclusively for the team.
On June 1, Marcus Mosher, host of the Locked On Cowboys podcast, tweeted: "I've seen some tough running backs in my time, but Marion Barber was one of the toughest. This is a tough one."
Co-host of ESPN's Fantasy Focus Football podcast Field Yates tweeted a Marion clip. The video shows the running back's two-yard run against the Patriots in 2007.
Yates wrote that Marion was a "tenacious runner"
His June 1 tweet said, "He always made something from nothing." "This 2-yard run was amazing. RIP."
