Police in Berlin released the photos of the English-speaking boy who walked out of the woods near the city limits nine months ago claiming he had been living in the forest for five years with his father.

Thomas Neuendorf of the Berlin Police Department said authorities have attempted to identify the boy since he arrived in the capital city on Sept. 5. They have been unsuccessful, but they are hoping that the photo will produce leads to the boy's identity, the Associated Press reported.

Despite extensive studies, the Youth Office and the Berlin police have not successfully identified the boy who calls himself Ray, police said in a statement issued Tuesday, the Globe and Mail reported.

Not much is known about the so-called Forest Boy; however, he informed police that his father calls him Ray and claims he was living in the woods for the past five years. When he walked into Berlin with his sleeping bag, tent and winter clothes, he was well groomed with his teeth, nails and hair all in good condition. His clothes appeared to be clean and neat and the tent he had looked new, the Globe and Mail reported.

He told police that he was born on June 20, 1994, which indicates he is just shy of his 18th birthday. Police said he could be anywhere from 16 to 20.

We have checked his DNA against all missing person reports, sent the data to Interpol so that they could check it internationally, but unfortunately without any success, Neuendorf said.

Investigators said that his DNA is indicative that he is from a neighboring country, as opposed to the United States. Authorities said that although the boy speaks fluent English, it is not his native language.

Authorities also observed three scars on his forehead, tree scars on his chin and another on his right arm.

He told authorities that his father's name was Ryan and his mother, Doreen. They had died. Ray said that his mother died in a car accident when he was 12 and his father died while out in the woods. However, he was unable to lead them to the body.

He was neither able to name nor show the place he had buried his father, the police said.

Ray was also reportedly unable or unwilling to give his family or any other biographical information that could to his identity, according to MSNBC.

There are many question marks, Neuendorf said, according to MSNBC.

Ray was able to adapt to life in in the city and with modern technology very easily. He had used a laptop and cell phone without any problems.

Everything gives the impression that he was not far away from civilization for years, Neuendorf told The Associated Press.

After a brief time in the emergency youth services, Ray was placed in an institution for assisted living and given a legal garden, the Daily Telegraph reported.

The youth office and the Berlin police have great doubts about the boy's story, they said in the police statement. That is the reason why the youth office now decided to publish a photo of Ray and ask for your help.
