Medical City Healthcare said its hospitals are still treating six patients from the mass shooting.

Three are in critical condition, two are in fair condition and one patient -- who is at Medical City Children’s Hospital -- is in good condition, officials said.

A woman was shopping when she says the shooting began and described how people began to flee for safety.

Elaine Penicaro said in an interview that she was finishing up her shopping when she heard "popping" noises and began to realize how dire the situation was.

"We saw sparks flying like it was right in front of us. So we just ran into the Converse store. They locked the door. We all hunkered down in the back. And that's where we stayed," she said.

Penicaro said she heard the police arrive within five to 10 minutes.
