A DeKalb County Wal-Mart was evacuated for about 90 minutes Wednesday morning after a suspicious package was found in the parking lot. The DeKalb police bomb squad examined the package -- a piece of luggage -- and determined it was not a threat, police spokeswoman Bettina Durant said. The bomb squad was sent to the store on Gresham Road after the luggage was discovered unattended about 9:30 a.m.
