Wendell Williams told ABC13 he thought he was hearing firecrackers until his son ran into their home.
He went outside and saw McKnight on the concrete.
"We flipped her over and tried to do CPR, but it didn't work," Williams said.
HPD says McKnight was returning from the grocery store when Flagg approached her, and asked to use her cell phone.
McKnight refused, a struggle broke out, and Flagg shot her multiple times, including one time in the back.
McKnight was pronounced dead at the scene.
Her son will never get his mother back.
"That was really sad and I've been thinking about that all day," Williams said. "It's pretty heartbreaking."
