Before the deadly shooting, officers got a call about a prowler in the area. Patrick Bryant was shot and killed Saturday night by responding officers.

WHBQ in Memphis, Tennessee, also found out that the officer's body cameras were rolling during the shooting. Multiple sources say the footage has already been reviewed.

Now, Triblett, Bryant's mother, wants answers.

“Somebody tell me the truth: They killed my son. ... They act like they didn’t know nothing,” Triblett said.

WHBQ met with Triblett as she was leaving the Clarksdale Police Department. She said she was there looking for answers.

Investigators said Bryant was killed a 15-minute walk away from his house. Family members said he was walking to the store to buy a cigarette.

He also had his 10-year-old son with him.

“My little grandson ran away by himself. ... He told his mother they killed his daddy,” Triblett said.

The police chief of Clarksdale would only tell WHBQ that their officers do wear body cameras. She would not talk about the investigation.

A neighbor wouldn't go on camera, but he told WHBQ that he heard Bryant threaten police.

Triblett said Bryant carried a gun because he was licensed as a security guard.

The Mississippi Bureau of Investigation told WHBQ that a weapon was found near Bryant's body in the backyard of the home.

“I want to know if my son was inside the house or outside the house – or around the corner. If you shot him in both hips, why would you shoot him in his heart?” Triblett said.

Bryant’s body has been sent to the crime lab in Pearl, Mississippi, for an autopsy.
