La Crescenta mother Megan DiPiazza, 33, is listed as an endangered missing person and was last seen Sunday night in the La Crescenta or Sunland-Tujunga area, authorities said.
Her car, a 2013 gray, two-door Scion has the license plate 6XJR885, Glendale Police Sgt. Robert William told Patch.
Investigators are looking for anyone with information about the Crescenta Valley High School graduate's whereabouts.
She is described as 5 feet 6 inches tall, weighing about 120 pounds, with blond hair and green eyes, said Los Angeles Police Sgt. Jim Reid of the Foothill Community Station. It's unclear what she was last seen wearing.
DiPiazza's family has taken to Facebook to encourage locals to contact police with any information about her whereabouts, said friend, Cheri Jones, via email.
Police attempted to track her phone, but found it off, Jones told Patch.
"I went to elementary school through high school with her and I hope she is OK. Please find out and get the word out," she said.
Friends and family on said DiPiazza apparently left her purse at home, according to her Facebook page. Her hair is also described as curly.
Anyone with information about Megan DiPiazza is urged to call Glendale Police Department at 818-548-4840 or the Los Angeles Police Department, Foothill Community Station, at 818-756-8861. To remain anonymous, call 1-800-222-TIPS.
