Investigators Find Space Heater On For Days In Fatal Fire

(Minneapolis, MN) -- Fire investigators have determined a space heater had been running for several days in a home where a fire killed five young children on February 14. The "Minneapolis Star Tribune" reports the fire department's report shows investigators believe the fire started in the area of the space heater, but due to the destruction it's hard to pinpoint the cause of the blaze. A six-feet-wide circle was burned through the third floor where the victims were sleeping. The duplex had smoke detectors, but investigators can't determine if they were working.
