TOUCHET, Wash. - The Walla Walla Sheriff's Office says horses were put in harm's way overnight, after someone decided to use a firework to blow up a mail box.
A Walla Walla officer tells us the mailbox exploded at about midnight near Rainville and Frog Hollow Road, right next to a pasture where horses were sleeping.
Metal went flying, but fortunately did not injure any horses.
As of early Monday morning, deputies still don't have a suspect lead.
Anyone with information should call the Walla Walla Sheriff's Office at 509-527-3265.
