The family of a 21-year-old whose spine was crushed during a police encounter with authorities in Duncanville, Texas, is demanding justice.

On the morning of Aug. 11, a woman called officers after spotting Keandre Green urinating in an alleyway. Green had been jogging that Monday morning and reportedly had stopped in an alleyway to relieve himself. Officers say when they approached Green, he fled.

Duncanville Police claim that officers on the scene did a computer search for Green before pursuing him and discovered that Green had a warrant for his arrest for a domestic violence charge.
