ALHAMBRA — A woman with Down syndrome who went missing Tuesday is safely back at home with her family, police said Wednesday.

Worried family members reported about 10:30 a.m. Tuesday that Chi Kim Truong, 51, had wandered away from home in the 600 block of Meridian Avenue and disappeared, Alhambra police Lt. Elliot Kase said.

Shortly before 7 p.m., police issued an alert to the public with Truong’s photo in an attempt to locate her.

A patrol officer spotted Truong about 7:45 p.m., standing at the corner of Atlantic Boulevard and Commonwealth Avenue, Kase said. The intersection is about a mile from her home.

“We don’t know where she was, but we’re happy to say she’s unharmed,” he said. Truong was reunited with her family.

Police will try to figure out where Truong went during the nine hours she was missing to give them an idea where to look should she ever go missing again, Kase added.
