Four men were found dead Sunday in a Tokyo apartment in what is believed to be Japan's latest suicide pact. It appeared the four died of carbon monoxide poisoning after lighting charcoal stoves in a room sealed with tape, police said. Japan has recently seen an alarming rise in suicides pacts, formed after the people involved met over the Internet. Last week in two separate incidents, six people were discovered dead in deserted cars, while in October seven people killed themselves. According to the National Police Agency, 45 people committed suicide in groups after meeting online between January 2003 and June 2004. Japan reported a record-high 34,427 cases of suicide last year.
