PINOLE (CBS SF) — A 75-year-old woman and her two grandchildren who have been missing since Sunday were found safe in Pinole and were reunited with family on Thanksgiving morning, the CHP said.

The car belonging to Sandra Young was spotted early Thursday morning on eastbound Interstate Highway 80 in the Hercules area.

At 8:33 a.m. Thursday, CHP reported on social media that they had possibly sighted Young’s vehicle on Willow Avenue in Hercules. Nearby Pinole police officers located Young and the two grandchildren in Pinole around 9:30 a.m.

A local gas station manager apparently saw the emergency alerts, went to the CHP Twitter page and saw photos of Young and the children. He recognized them as individuals at his gas station, contacted 911 and Pinole police responded to the location, CHP Golden Gate said.

Young has lived with the children, ages 7 and 9, since their parents were killed in a car crash in 2012, Fairfield police said. Young talked with her sister Sunday but has been out of contact
since then, according to police.

Young and the children are considered at risk due to the children’s ages and Young’s medical condition. She has custody of the grandchildren, but family members say her leaving without contacting them is out of character, police said.

There is no crime involved, CHP said.
