Police said Wednesday the results of their initial investigation into Tuesday's tragic subway blaze in Daegu points to the failure of subway officials to take adequate steps to deal with the emergency as one of the major causes of the massive loss of life in the deadly inferno. The Daegu Metropolitan Police Agency said arson suspect Kim Dae-han admitted to the attack and that the mentally-troubled 56 year old had told investigators he "believed it was better for him to die along with other people than to die alone." Estimates put the death toll at 120. Police said Kim left home around 8 a.m. and boarded a subway train heading for Ansim Station after buying gasoline near his home. Kim then set fire to the train as it was arriving at Jungangno Station. Police plan to question the suspect further after he recovers sufficiently from smoke inhalation and burns. The driver of a six-carriage train that arrived at the same platform where the blaze broke out, has already said he received no special instructions from the control center other than to show caution as an accident had occurred at the station ahead. The driver said he continued toward Jungangno Station but his vision was limited due to billowing smoke. When the train arrived at the station, he opened the doors but instantly closed them as smoke and toxic fumes were spreading into the subway carriages. He also said he eventually opened the doors after passengers urged him to do so and then ran for safety. Sources said that the police investigation will focus on the contrasting statements of the driver and other subway officials and on claims that scores of lives could have been saved if the driver's train had not pulled into Jungangno Station. Police are also looking into the possibility of technical problems on the train as he said the doors could be automatically closed in the event of an accident.
