Someone's running around dressed like a congressman.

Rep. Jim Kolbe's house in Sonoita was burglarized July 23 by a suspected group of undocumented migrants, said Santa Cruz County Sheriff's Lt. Ramon Fuentes.

The burglary was reported shortly after 5 p.m., when one of Kolbe's local friends noticed one of the home's doors was wide open. Sheriff's deputies, Patagonia Marshal's deputies and Border Patrol agents quickly responded.

It quickly became apparent that the culprits weren't interested in big-ticket items, because electronics and other valuable items were left largely untouched, Fuentes said.

Instead, the burglars focused on fixing a snack and getting cleaned up. Kolbe's microwave showed signs of recent use, as did his shower. Officers found wet towels piled up in the bathroom.

Before leaving the house, they took a snack and a change of clothes.

"They're going to be some sharp dressers," Fuentes said.

Investigators were unable to determine if anything other than food and clothing were missing. Fuentes said the case will remain open until Kolbe inventories his belongings.
