Two more mailbox bombs found in northeast Kansas

EUDORA, Kan. | Authorities are investigating after two more mailbox bombs were found in the Eudora area in northeast Kansas.

The Lawrence Journal-World reported on its Web site that no one was injured when the devices — made of liquid Drano and aliminum foil — went off.

Authorities learned of one of the devices when residences called and reported hearing an explosion Friday morning.

A mail carrier found the second detonated bomb Friday in a mailbox just outside the Eudora city limits.

On Thursday afternoon, a mail carrier found an unexploded bomb filled with the same substance in a Eudora mailbox. The Olathe bomb squad detonated it.

The U.S. Postal Inspection Service is offering a reward of up to $1,000 for information leading to the arrest and conviction of those responsible for the explosives.
