The police were alerted to her disappearance by her father, NBC New York reported. The concerned parent, who lives in California, said she always called him at 6 p.m. each evening and he got worried when she didn’t get in touch.

Quigley’s cellphone was found in a bridal store in the Chelsea area of New York, but her dad said she could have been there picking up clothes for a show.

However, he said she recently made a strange comment to a friend, saying: “Get ready, it’s about to happen and I’m going to need you to sub for me.”

Missy Elliott also posted about the dancer, asking anyone who may have seen her to “contact the North Bergen police 201-392-2100.”
