Police and relatives of a missing Mid-City mom are asking for the public’s help in finding her.

Three days later, on Oct. 20, Planck was not present to pick up her son from school in the 1500 block of Selby Avenue in Westwood.

“I’ve got a 10-year-old boy who’s just beside himself,” said Jim Wayne, Planck’s ex-husband.

Planck has blond hair and blue eyes, is 5 feet, 3 inches tall and weighs about 120 pounds. When she was last seen, she was wearing jeans and a gray sweater and was driving a gray 2017 Range Rover with California license plate U840X0.
