Apparently the case of the stolen fiberglass egg in Spokane Valley won’t be over easy.

The large and heavy piece of public art taken from Discovery Playground two weeks ago has not turned up.

It’s the third time since the park opened in 2010 that someone has stolen one or more of the eggs, Spokane Valley Parks Director Mike Stone said. And in 2011, a 5-foot-tall, yellow fiberglass inchworm disappeared and was never found.

“Last time the eggs disappeared a bunch of minors posted pictures on Instagram with the eggs like it was a trophy,” Stone said. “Someone recognized them and called mom. She quickly swung into action and we got the eggs back.”

No such luck this time.

The missing egg is about 2 feet high and 2 1/2 feet long, and it’s part of a cluster of three eggs. The other two resemble broken shells from a hatched chick.

Stone said he’s surprised someone was able to get the egg out of the park area.

“It weighs 200 or 300 pounds and you have to lift it over the fence,” he said. It’s also too large to fit in the back of an ordinary car, he added.

The eggs aren’t cheap, Stone said. “Five or six years ago all three of them were $9,200,” he said.

Stone said the city has been contacted by a local artist who said he may be able to do something that’s as good as the missing egg but more difficult to steal.

There are no security cameras at the playground, but Stone said it’s possible someone in nearby apartments saw the caper. He hopes someone will call with a tip, and he guarantees anonymity.

“Is someone really going to display this in their yard? No, I don’t think so,” Stone said. “We just want it back.”
