“We waited 45 minutes. I was waiting to catch her. It wasn't going to be pretty. She never showed up,” she said.
Police were called and Maura Wallen her boyfriend, Calvin Coragall, were later arrested.
“It really aggravates me. I'm 10 minutes away. I wouldn't have cared to watch them,” Daniell Wallen said.
