DALLAS (CBSDFW.COM) – Police in Dallas released a picture of a suspect who, they said, they had to find after 12 officers were shot and five were killed Thursday night during a march protesting police violence against black men. That man, Mark Hughes, brother of protest organizer Cory Hughes, turned himself in to police on Thursday night.

Hughes was released from custody shortly after 1:00 a.m. on Friday.

“I just got out of the interrogation room for about 30 minutes with police officers lying, saying they had video of me shooting, which is a lie,” Hughes told CBS 11 News live on the air. “That they have witnesses saying I shot a gun, which is a lie. I mean, at the end of the day, the system is trying to get me.”

Cory Hughes stated, hours earlier, that his brother, who had been walking around with a rifle, did not shoot anyone. Just after doing a live interview with CBS 11 News, Cory Hughes went to talk to the Dallas Police Department and, not much longer after that, Mark Hughes turned himself in to authorities.

“I am so overwhelmed with emotion right now,” Cory Hughes added shortly after his brother was released from custody. “I’m trying to be strong right now for my family that I know is watching, but I’m crying on the inside, because we simply came to be a voice for those that don’t have a voice. And we went from being a voice to being suspects and being villains. And my question is why?”
