Nearly two months ago the McStay family vanished.
Earlier this month, the San Diego County Sheriff’s Dept released surveillance video that may have captured the McStay family entering Mexico.
The video was recorded at the San Ysidro border crossing Feb. 8, the same day the McStay's white Isuzu Trooper was found illegally parked at a nearby strip mall.
At the bottom left corner of the video, a man can be seen walking hand-in-hand with a child. Following him is a woman in a white jacket, holding the hand of another child.
"There's a very high probability it's them,” said Brugos.
Detectives showed the video to the McStay's relatives. Some recognized the white jacket that the woman is wearing in the video, but other family members aren't sure it's them because of the poor quality of the video.
"It's very grainy, overshadowed, there's no definition to shape,” said Mike McStay, Joseph's brother.
Since their disappearance, investigators said, the McStays haven't used their bank accounts, credit cards or cell phones.
