A New Jersey woman's family is desperate for information on her whereabouts 12 days after she vanished without a trace from her home in the suburbs about 25 miles southeast of Philadelphia.

Norma Yates, a 62-year-old from Atco, was last seen around 5 p.m. Saturday, July 29, by a construction crew working at her neighbors' house.

The following morning, she missed a coffee date with a friend, according to her daughter.

There was no sign of Yates at her home, but her pocketbook and cellphone were left behind.

Family friend Shaena McCoy told Fox News Digital that neighbors checked their home surveillance cameras and found no signs of Yates coming or going, leaving the family "super perplexed."

"This is a mom that’s extremely involved with her children, her grandchildren, talks to her kids every day," she said. "No new boyfriend in the picture – her daily routine was hanging out with her neighbor, having coffee, spending time with the kids."
