Eudora ? Two more mailbox bombs made with liquid Drano and aluminum foil were found in Eudora.

Residents in the 1300 block of Acorn Street notified police Friday morning of an explosion that occurred between 8 p.m. and 10 p.m. Thursday.

Members of the Eudora Police Department found the remnants of an explosive device in the mailbox of a residence at the location. The occupants were not present at the time of the explosion.

A mail carrier on Friday found a second detonated bomb in a mailbox near the corner of Winchester Road and 10th Street, just outside the Eudora city limits.

On Thursday afternoon, the Olathe bomb squad detonated a bottle filled with the same substance after it was found in a mailbox at a home in the 1400 block of Fir Street. The residents of the house were not home.

Eudora Police Chief Greg Dahlem met with officials from the U.S. Postal Inspection Service, which is offering a reward of up to $1,000 for information leading to the arrest and conviction of those responsible for the explosives.

Anyone with information on the incidents is asked to contact the U.S. Postal Inspection Service at 877-876-2455 or the Eudora Police Department at 542-3121.
