A Miami-Dade County worker says he knew exactly what to do after witnessing a violent hit and run accident Tuesday afternoon.
"Something just told me to try and help," said Mark Brown. "Everything happened so quickly."
Brown is being hailed a hero after he stopped 48-year-old Rolando Aliaga in his tracks just blocks away from the crime scene.
Brown expressed how he felt as he witnessed the tragedy unfold right before his eyes.
"First disbelief, I guess, that was the first thing, like 'wow, is it real?'" Brown added. "It was a sad day for all of us."
Samuel Vincent's only son Tyron Richemond was heading home from class at Miami-Dade College when his life was cut short. Vincent says thanks to Brown he now knows who's responsible for his child's death.
"He's a hero...he did a good job," said Vincent. "God Bless him too."
Brown's heroic action was even recognized by James Loftus, The Miami-Dade Police Director. "We expect it from our cops, but when our citizens do that, its truly phenomenal."
The second victim, Charles Williams is listed in serious condition at Jackson Memorial Hospital.
Brown turned down the hero talk and said he's more worried about the victims.
"I'm just an average citizen who's working and concerned about the family," Brown said.
Rolando Aliago remains in jail facing a number of charges, including DUI manslaughter, leaving the scene of an accident involving death and serious bodily injuries and DUI property damage. He's being held on over $90,000 bond.
