This is so crazy!

TOKYO, Nov 28 (Reuters) - Four young Japanese men were found dead in a Tokyo apartment on Sunday in what police said may be the latest in a series of Internet suicide pacts that have claimed dozens of lives in the past two years.

The bodies were found by a friend of one of the four after a key to the apartment was sent to him in the mail, a Tokyo police spokesman said.

The men appeared to have lit charcoal stoves in a room sealed with tape and died of carbon monoxide poisoning. Two had been identified as salaried workers in their twenties, while the other two appeared to be in their twenties or thirties, police said.

Charcoal stoves are a favoured method for those Japanese who choose to commit suicide in groups formed via the Internet.
