SAN DIEGO (AP) — A thief who posed as a guest at California weddings and stole wallets, credit cards and cash from brides, guests and wedding workers will be honeymooning in prison.

KNSD-TV (http://bit.ly/1oCYBzm ) says Denise Gunderson was sentenced Wednesday to seven years behind bars. She has previous felony convictions.

Prosecutors say last year, Gunderson showed up at several San Diego County weddings, went into rooms and offices and stole valuables during the ceremonies.

Authorities say Gunderson used the credit cards to make thousands of dollars in purchases at Costco, Walmart and other stores — sometimes only minutes after the wedding vows were taken.

Surveillance video caught Gunderson at several wedding locations and stores.

She was arrested last December in Las Vegas and pleaded guilty in February to grand theft and identity theft.
