The leads looked promising.
But there was one hitch.
Photos found with Boatwright in the motel room showed a young man living in what looked like a European city, not Asia.
Hunt-Vasquez kept searching.
She came across several websites dedicated to graphic designs. Boatwright often used the screen name 'korstemplar' and listed himself as a Swede living and teaching in China.
The pieces were falling into place.
He had lived in Japan, married, became a father. He then moved to China.
The school in China told her he was divorced.
He lived there until May, when his visa expired and he flew to California.
But when she contacted the Japanese and Chinese consulates, neither had next-of-kin information for him, according to the Desert Sun.
Staffers called all the numbers on the phone Boatwright had with him. They either went to voice mail or no one picked up, the newspaper said.
She had hit a dead end.
His life so far
Everything Boatwright knows about his life before February 28 he knows because his social worker told him or because he read it on websites.
He told CNN he learned that in 1987 he operated a consulting company called Kultur Konsult Nykoping.
That is somewhat of a Swedish connection.
He doesn't have any independent knowledge of his life before he woke up in the hospital. He doesn't even know exactly what his consulting company did.
Boatwright told CNN he'd been a good tennis player, and the Tennis Channel had interviewed him years ago.
Perhaps, he said, he'd come to southern California for the tennis tournament season. That would certainly explain the five rackets in his hotel room.
A 'fugue state'
According to the Desert Sun, Boatwright is in a "fugue state."
People in this condition lose their sense of personal identity, according to the Cleveland Clinic. They become confused about past events and often wander far from home.
Fugue states, such as dissociative fugue, are often triggered by trauma, such as the death of a loved one or a serious accident, according to Dr. Aaron Anderson, a neurologist at Emory University School of Medicine.
Patients sometimes assume different personalities, Anderson added.
