Forest Park man shot, killed with family at home
Forest Park police are looking for the person who opened fire, shooting and killing a man who was sitting outside his home. The victim's brother wants justice.
John Randle, who told FOX 5 he was the victim's brother, said he overheard an argument between a woman and a man walking by along Burks Road on May 20.
"The altercation turned into threats. Then, after threats were made, the guy pulled out a gun and started shooting multiple rounds," Randle said.
One of those rounds hit and instantly killed his brother.
Hernandez was taken into custody after a brief manhunt Friday evening.
