Police received a call from an East Kennewick man around 10 p.m. Tuesday. He was cleaning up belongings from a family member that had recently died.
The man came across a box with what appeared to be a homemade pipe bomb.
The bomb squad was called out. They detonated the device in a Kennewick field between 10th Avenue and Fairway Drive.
There were no injuries, and it was successfully detonated, but police say a very loud explosion could be heard throughout town.
