Authorities asked the public Wednesday to keep an eye out for a Point Loma Heights mother of three who went missing this week.
Rosa Lisowski, 48, has been unaccounted for since about 7:30 a.m. Monday, when she walked her son to Barnard Elementary School, according to San Diego police.
She did not have her wallet, identification or money with her at the time, officials said.
Lisowski, who apparently has been in a protracted child-custody dispute with her estranged husband, is a 5-foot-2, roughly 165-pound Latina, with black hair and brown eyes.
At the time of her disappearance, she was wearing dark-colored sweat pants, a black hooded jacket and leather "flip-flop" shoes, police said.
Authorities asked anyone with information on Lisowski's whereabouts to call SDPD communications at (619) 531-2000.
