Search teams are back out Monday looking for a skier who went missing on Whiteface Mountain.

Constantinos "Danny" Filippidis, a 49-year-old firefighter from Toronto, disappeared last Wednesday during a snowstorm.

Officials are urging anyone who may have been in contact with him to call the police. And they're asking anyone who might have been on the mountain Wednesday using a GoPro camera to call New York State Police at 518-873-2750.
