What witnesses inside the store experienced
Hanna Manker said she was inside the store, as she often is a few times a week, when gunshots rang out. She had her two young children with her.
"My kids and I went to get some groceries, their dad ended up showing up to help us. Thank God, at the end of it, checking out we heard about five or six shots. Everybody started running I didn't know what to do so I ducked down with my kids," Manker said.

Manker said the experience has left her family shaken.
"I think we're all traumatized. I don't know if we'll ever be able to go into a store shopping again, honestly,"Manker said.
A vendor at the store who did not want to be identified said it was chilling to see who she believes to be the suspect's demeanor.

Then I hear another range of shots, probably around 5 to 6... I don't know what happened. I just walked over there towards him. He pulled out his gun. We're wrestling for the gun. I didn't even know until after I pulled the bag of weapons away from him, he had other weapons in the... in his backpack," Clark said.
