The state fire marshal's office released photographs Wednesday of the "melted mass" at the heart of a February fire that killed five children in North Minneapolis.

An attorney for the family said they plan to do a detailed analysis of the mass -- thought to be a space heater -- this August, when a number of experts are available to collectively review the object. It has already been x-rayed, he said.

"It hasn’t been analyzed beyond that,” Sieben said of the object, which possibly could include other melted items. “That’s just a real preliminary piece of testing. There is going to be some extensive testing of it done.”
