Kevin Michael Hagan suspect admitted to breaking into Pelosi's residence and five others, according to authorities. The homes were burglarized in the weeks since October 31.
Sheriff's investigators found Hagan in possession of a watch stolen from Pelosi's home in the Monday burglary. Pelosi's home is located outside St. Helena. An alarm alerted authorities. She was not home at the time of the burglary.
Hagan was arrested Wednesday when he was found and arrested at another St. Helena home where a break-in was reported.
Authorities said they did not believe Pelosi's break-in was politically motivated.
