The family of a missing Dartmouth woman is making a national plea for help in finding her.

Catherine “Catie” Miller, 29, was last in contact with her family on July 15. She hasn’t been seen or heard from since.

Her father, John Miller, says he doesn’t believe his daughter had planned to leave the area. He says she recently had cable installed at her apartment, was making appointments, and left her cat at home without food and water.

Catie’s cellphone and bank accounts have not been touched since July 15.

“Since the buses and the planes and the trains have been checked, she doesn’t have her own car, so if she’s gone in somebody else’s car, it’s been long enough that she could be anywhere in Canada,” says Miller.

The Miller family is planning a candlelight vigil for Catie in Halifax’s Grand Parade next week.

Catie is described as a white female with brown shoulder-length hair and grey eyes. She is about five-foot-eight and weighs 130 pounds.

Police say her ears are pierced and she has no known tattoos. She often wears her hair in a ponytail.

Anyone with information on her whereabouts is asked to contact police.
