The man police say shot another man outside a jewelry store inside a mall in Mishawaka is still on the loose say investigators.

Delaney Crosby, a 23-year-old man, was killed when another man whom he had gotten into an argument with pulled out a gun and shot him. Megan Nunemaker, who works at the University Park Mall, saw it all go down.

“We just stood still, try to stay silent. I didn’t have my phone or anything so I couldn’t tell anyone,” she said. “It was traumatizing absolutely to me. I don’t feel safe anymore going anywhere – especially the mall, which I love so much.”

Ast. Commander Dave Wells with St. Joseph County Metro Homicide says they believe Crosby was targeted by the killer. He says it was a “stupid idea” for the shooter to commit such an act of violence in a crowded mall on the weekend.

“Of course any shooting is a stupid idea, but to do it inside a mall where there’s many witnesses,” Wells said. “I’m encouraging the person who did this … it’s only a matter of time before we find you, to call us and turn yourself in and make this right.”

Homicide detectives have interviewed several witnesses so far. They say it appears the shooting was also caught on video footage from mall surveillance cameras which detectives say they are still sifting through.
