The family of an Illinois infant that died in a house fire has filed a lawsuit claiming that an Xbox video game system manufactured by Microsoft and sold by Wal-Mart Stores overheated and sparked the killer blaze, say media reports. According to the suit, the wiring that connected the Xbox 360 to an electrical outlet became so hot that it started a "catastrophic" fire at a house in Warsaw, Illionis. The victim, an infant named Wade Kline, died in the inferno.
