A Tri-Valley family had an unwelcome surprise waiting for them Tuesday when they returned home from vacation to find their liquor cabinet raided, some personal items stolen and pounds of bacon pilfered.

The residents returned to their home in the Castlewood neighborhood of unincorporated Pleasanton and called deputies around 11:15 a.m. after they realized their home had been the site of a party while they were away, Alameda County Sheriff's Sgt. Ray Kelly said.

Kelly said a group of juveniles entered the home sometime during the week the residents were gone and threw a party, cooking and eating five pounds of the homeowners' bacon and washing down the meat with the residents' liquor.

The intruders also took pictures of their bacon-and-liquor party and posted images on social media, which sheriff's deputies have found.

Kelly said about $2,000 to $3,000 in personal property was stolen, including some jewelry.

The number of people involved in the party and their identities will not be released because they are underage, Kelly added. They will be given notices to appear in court, rather than being formally arrested.

"We're rounding them up one by one," he said.

Kelly said it's suspected the homeowners might have posted about their vacation on social media before they left, leaving their home vulnerable to intruders.

With many families taking vacations over the summer, he recommends travelers keep their home safe by avoiding public posts about vacations while their houseswill be unattended, hiring a house sitter or asking an adult friend to regularly check on the home, as well as stopping mail and newspapers while away and enabling an alarm service and video cameras.
