Police said Marta Michel was last seen waiting for a bus last Saturday at 4th Street and Broadway in downtown Los Angeles. Coworkers said they saw her waiting at the stop after her night shift.
The missing woman's loved ones fear that she may have been kidnapped. They said she doesn't have a cellphone and was not carrying identification.
"What if somebody took her and still has her? That's what we believe, because she wouldn't leave," said Michel's young daughter, Diana.
Michel is described as a Hispanic woman standing about 4-foot-11, 160 pounds with black hair and brown eyes. She was last seen wearing a gray and white horizontal striped skirt and a gray blouse.
Anyone with information on Michel's whereabouts was asked to call Detective Lydia Saiza of the LAPD Missing Persons Unit at (213) 996-1800 or (877) LAPD-24-7.
