When he woke up at Desert Regional Medical Center, nurses asked him questions and he said he'd never heard of Michael Boatwright. He also didn't know a woman seen in a photo with him.
A hospital social worker helped Boatwright set up a Facebook page, and she discovered he did live in Sweden in the 1980s and ran a consulting company. He lived in China, too, teaching English.
On the school website, Boatwright's own essay reveals he was married to a Japanese woman and had a 12-year-old son. But he says he doesn't remember any of it.
So why was he in Southern California? He had tennis rackets with him and clues suggest he's a tennis coach.
Doctors believe Boatwright is suffering from transient global amnesia, a condition triggered by physical or emotional trauma that can last for several months. They said it could be from stressful or life-changing events, family deaths or major accidents.
For now, Boatwright remains in the hospital waiting to find out where his life is.
