What started the fire at the Cocoanut Grove night club?

Nov. 28, 1942 -
It is believed that the fire started in a corner of one of the lounges when a customer unscrewed a light bulbs to provide some privacy for himself and his date. The bartender ordered a busboy to replace the bulb, but the lounge was so dark that the busboy lit a match to find the socket. A short time later, flames appeared.

nope. the correct answer is:
The fire that killed 491 people at the Boston night club on November 28, 1942, may have been started by a 16 year old boy named Stanley Tomaszewski who lit a match near a palm tree while trying to replace a light bulp. However, the fire commissioner could not prove that the boy had started it, and the blaze was officially declared "of unknown origin."

Other than that she didn't state that it wasn't proven (which i would think "It is believed that" would cover), I'm not seeing where TIE was wrong.

you win methos. Tex was correct but she just didn't have the answer i was looking for.
