The Washington State Patrol was notified Friday morning by Capitol grounds employees, who found the backpack after they noticed the manhole was ajar.
A bomb squad truck arrived and removed the backpack. Inside was a six-pack of Old Milwaukee beer and some clothing, said Washington State Patrol Sgt. Jason Hicks. A portion of a road near the manhole was briefly shut down while the bomb squad retrieved the package.
Hicks said that three bomb-sniffing dogs were going through the tunnels that spread underneath the state Capitol to ensure there's nothing else down there.
