Flags stolen from Main Street in Echo, Ore.

A town named Echo in Eastern Oregon, population 715, is short 15 American flags stolen earlier this week from Main Street.

City Administrator Diane Berry said it’s likely they were stolen at night — there aren’t any street lights.

The East Oregonian reported Wednesday that the city kept the flags on display after the Fourth of July because it was time for the all-school and all-city reunion held every five years.

Berry said she wonders whether someone was trying to send a message to the city and says she “can’t imagine why a mature person would conceive of doing that.”

The reference book “Oregon Geographical Names” says Echo was named for the daughter of an early town settler. It’s along Interstate 84 in Umatilla County.
