WRENTHAM - A local teenager who had been missing since Tuesday and was found in a confused state at a Dedham home Thursday, was suffering from the lingering effects of a severe concussion he sustained last fall, according to police.
Wrentham police, in a press conference about the incident Friday morning, said Matthew P. Glass, 17, a senior at King Philip Regional High School, was not abducted and that they were closing the investigation into the teenager's disappearance
"All of what happened with his disappearance is related to his head injury," said Wrentham Detective Lt. William McGrath. He said toxicology tests showed Glass did not have any drugs or alcohol in his system and that he was dehydrated and confused as a result of the head injury he received last fall while playing football.
He said Glass, who turned up at the random home in Dedham on Thursday saying he had been abducted, later did not know why he had said that.
Police said they also determined that Glass had not run away from home because he had been out of contact with anyone since his disappearance.
Diane and Michael Glass thanked the media and Wrentham, Boston and the state police for working on the incident.
Diane Glass said that while fearing the worst after her son went missing, she and her family never gave up hope he would be found.
"We still think this is the lingering effects of a bad concussion," Diane Glass said during the press conference. Her son had passed out twice in school since getting the concussion.
She said the two hugged when they were reunited in the hospital Thursday.
Glass, getting teary as she talked, said, "He's just happy to have his family."
