Michael's father Walter told ABC 7 that his son may be headed to Times Square as he has been there before with his family. Marlboro Police are following a lead that Michael may have taken a NJ Transit bus to Manhattan according to the Asbury Park Press.

Lloyd, New York Police posted on their Facebook an alert for Michael as he may have been seen at the Bridgeview Plaza shopping center in Highland, New York. Lloyd is located in the Hudson Valley, 112 miles north of Marlboro along the Hudson River.

Karwan left his home on Tuesday night following an argument without his cell phone or wallet.  He normally returns home after clearing his head but this time he did not. His father Walter has posted a $25,000 reward for information as to his whereabouts. He is concerned for his son's health given the cold weather coming our way for the weekend and the showers expected on Friday night.
