Have two missing children been found? Unrelated cases may be solved.

In New Mexico and Germany, two people in unrelated cases are claiming to be children who went missing years ago.

An 18-year-old man in New Mexico says he is Robbie Romero, who missing 11 years ago. The case was treated as an unsolved homicide, but no body was ever found.

For years, Ronnie Romero, Robbie's older brother, was a person of interest in the case. He was never charged. He died in prison of a drug overdose in 2009. Robbie's father, Rudy Romero, has also passed away since Robbie originally disappeared.

The man has agreed to a DNA test to prove his identity, ABC News reports.

If his identity if confirmed, many questions are certain to follow, including what happened to him in June 2000. You can watch a video from Albuquerque's KOIT below.

And in Berlin, a teenager says he has spent the past five years living in the woods with his father. The boy, who speaks fluent English and only a little German, is believed to be about 17.

The teenager says his father died in a fall in the woods, the Associated Press reports, so he followed his compass north for two weeks until he reached Berlin.

He says his first name is Ray, but he cannot remember his last name. Officials from Germany's Missing Persons Bureau are seeking help from other European nations in identifying him.
