SANDPOINT — A preliminary hearing is set for today in a burglary case pending against the son of a federal prosecutor.

Christopher Alan Cook’s arrest stems from a series of theft cases that one of the victims  managed to crack using a software application on his smartphone.

Cook, a 22-year-old from Dalton Gardens, is charged with burglarizing six vehicles parked in a residential area in December of last year.

A Motorola Droid phone was stolen from one of the vehicles and the handset’s owner used an app designed to locate missing devices using GPS technology. The victim used a laptop computer to track the device to a dwelling in the 100 block of Fourth Avenue.

Sandpoint Police obtained a search warrant after a stolen snowboard was positively identified through a window in the residence, according to court documents.

Sean Brendan Mahoney, also 22, was arrested and charged with felony theft by possession of stolen property. He pleaded guilty to a reduced charge of misdemeanor theft in an agreement with the state.

A condition of the agreement required him to give up his alleged accomplices in the string of thefts, which resulted in Cook’s arrest on a $5,000 warrant. A third suspect is wanted on a $10,000 warrant, court records show.
