Owner Pete Evans said he's staying strong.
"In this area, I mean there may have been 20 break-ins," Evans said. " I knew they were coming... I even spent the night in my parking lot on a couple of nights. I just didn't guess the right night, but I knew they were coming, and they may be back."
Police are reviewing surveillance and are reminding other owners to check security.
