Jacob Kiss turned himself in to police on Tuesday, with an alleged accomplice. The 19-year-old also brought along the Gumby costume he wore on Labor Day during an attempted robbery.
Police say a man dressed in a Gumby costume and an accomplice went into a 7-Eleven in Rancho Penasquitos and told the clerk it was a robbery.
The clerk thought it was a prank and dismissed him. Both then left the store.
Officials say the surrender was voluntary. Authorities are now deciding whether to prosecute.
