UPDATE: Shipley's headmaster sent out a letter stating Wylie likely took his own life.

A standout teenage soccer player from Montgomery County vanished this week, and police from multiple jurisdictions are working together to try to find him.

Austin Wylie, who recently finished his junior year at the Shipley School in Bryn Mawr, was featured in September as the Main Line Boys Athlete of the Week for his achievements as Shipley's forward.

Friends are taking to Facebook, Twitter and other social media to share photos of Wylie after they said he went missing Wednesday morning.

A spokesman for Lower Merion Police Department told NBC10 that a number of law enforcement agencies from different jurisdictions are investigating Wylie's disappearance.

He confirmed that a car Wylie had been driving at some point was located at 5th and Spring Garden streets in Philadelphia since the teen went missing, but wasn't able to confirm whether the keys had been left in the car, as reports on social media have said.

Anyone with information on Wylie should contact Lower Merion Police at 610-649-1000.
