READFIELD -- A local family's search for their teenage son has turned desperate.

David Robinson, 16, wrote a note telling his parents they would never see him again before leaving his Terrapin Drive home with just an extra pair of sneakers and his bicycle last week.

Robinson, who was last seen at home before he went to bed around 9:30 p.m. Wednesday, was spotted Thursday morning at Readfield Family Market but has not been seen since.

"There's nothing we can do. That's the hardest part," said Tracy Robinson, David's mother, after spending much of Monday posting fliers with her son's picture. "We don't know if he's dead or alive."

Maine State Police Trooper William Baker said he continues to investigate any information he gets and police throughout the region are on the lookout.

"I just don't know what else to do," Baker said. "At this point, I'll take any information I can get."

There is nothing that indicates foul play, but Baker said the incident makes him uneasy. "There's something about this whole thing I don't like," he said.

David Robinson took no money and had no cell phone.

"He's just disappeared," Baker said, "which is bizarre for a 16-year-old."

David Robinson has much longer hair than he does in the photo Tracy Robinson is circulating, but her son wears the same black fleece made by Hot Chilly's and brown "Bowtech" baseball cap every day.

The Robinsons adopted David, who is to begin his junior year at Maranacook Community High School in the fall, when he was 5. He signed the note to his family by his birth name, David Crocker.

"To me, that was a sign of separation," Tracy Robinson said. "I think it sounded like he was done with life."

Anyone with information is asked to call 1-800-452-4664.
