So it's a shirttail we see in the photo. Not a fanny pack.

"(Indiana State Police Superintendent Douglas Carter) quoted:
He pointed to the picture that had already been released.
"Someone knows who this individual is," he said. "Someone knows who this individual is. Is it a family member? Is it a neighbor? Is it an acquaintance? Is it an associate? Or maybe that one guy that lives over at that one place that's just kinda not right?"
"Maybe it's his jeans," he added. "Maybe it's his jacket or his sweatshirt.
Maybe it's his shirttail. Maybe it's his posture. Maybe it's the right hand in his pocket."
"As poor as this picture is, somebody knows," he said.
And he had a message for the suspect:
"If you're watching, we'll find you."
