Consider the case of the convenience-store-robbing “Gumby” bandit closed.

Two 19-year-old men turned themselves in to San Diego police Tuesday as suspects in the “Gumby robbery” earlier this month of a local 7-Eleven store.

Jason Kiss confessed to wearing the Gumby costume and his friend, Jason Giramma, admitted that he was the driver of the getaway car, police said.

The real evidence that sealed the case closed, however, was the full-body, green Gumby suit Kiss brought with him to the station on Tuesday.  Police confiscated the suit as evidence.

The Labor Day robbery ended up netting the boys only a few pieces of loose change when the clerk at the Rancho Enasquitos 7-Eleven store Kiss entered dressed as the long-running TV character thought the whole thing was a joke.

Gumby, the green, clay humanoid subject of a 35-year television series, was created in the 1950s by the late Art Clokey and his wife, Ruth.

When Kiss, dressed as Gumby, asked for a pack of cigarettes and told the clerk “this is a robbery,” the clerk told him, “Come on man, don’t waste my time. I have things to do,” ABC News San Diego affiliate KGTV reported.

Kiss then told the clerk he had a gun and fumbled around in his Gumby costume, appearing to search for it.   When a gun never materialized, Kiss rushed out of the store into the getaway car driven by Giramma.

The whole episode was caught on tape by the store’s surveillance video, which also shows Kiss struggling to keep the green suit on as he walked out the door.

A $1,000 reward from San Diego Crime Stoppers, prompted tipsters to identify Giramma as the driver, police said.

Neither Kiss nor Giramma were arrested, and both were released by police on Tuesday.

The case will be sent to the local District Attorney’s office to decide whether it merits criminal charges or should be classified as the joke the 7-Eleven clerk believed it to be in the first place.
