A Queens family is asking for help finding their teenage son, who's been missing since Thursday.
Aidan Norvez, 18, is a Type 1 diabetic who depends on insulin.
His family says the Brooklyn Tech senior went to Central Park with friends after taking an exam.
He told them he was taking a subway home to Queens, but hasn't been seen since.
His parents say he was not wearing his medical alert bracelet at the time.
"Maybe somebody came across him if he had a low blood sugar and tried to help him," said Tara Norvez, Aidan's mother. "He could be unconscious in the hospital somewhere. He's not wearing his medic-alert band, so there's a possibility that they may not know he's a Type 1 diabetic."
Q:What do you think happened with your son?
Claude Norvez, Aidan's father: I don't know. He's got a lot of a stresses in his life right now, with college and considering going to the seminary. I really don't know. I honestly don't know. I'm hoping for the best.
Norvez is 5 feet, 11 inches tall and weighs 130 pounds. He has brown hair and brown eyes.
He was last seen wearing a black sweatshirt, a navy blue shirt, dark brown jeans and gray sneakers.
