San Diego County Sheriff's Department investigators say surveillance video may have captured images of the McStay family, Joseph, his wife Summer and their two boys Gianni and Joey, crossing the U.S.-Mexico border into Tijuana on foot last month.

Joseph McStay's brother, Michael, says he went to the home on Feb. 4 to check on the family, but only found the dogs. He called authorities the next day, but investigators found no signs of a struggle.

Four days later the family car, and Isuzu Trooper was found abandoned in a San Ysidro shopping mall, a bordertown outside of San Diego.

Sgt. Roy Frank said Friday that the video was shot at the San Ysidro Port of Entry on Feb. 8, four days the family was last seen.

The tape shows a family casually strolling across the border. Investigators allowed McStay family relatives to view the surveillance tape, but they too were unable to make a positive identification.

Investigators have not released the video, saying it is part of and active investigation.

Relatives say it's out of character for the family to disappear, leaving their dogs at home and rotting food in their kitchen.

Detectives say they have found no evidence that the McStays had financial problems or were facing threats.
