After a nearly yearlong investigation, officials in Indiana said they have been unable to determine the exact cause of a fire that killed six children in South Bend in January, but investigators have found no evidence of a crime.

SOUTH BEND — Investigators still have not determined a cause of the fire that killed six young South Bend children in January. After a nearly 11-month investigation, Indiana State Fire Marshal Steve Jones said, there is not enough scientific evidence for investigators with the Indiana Department of Homeland Security to determine an official cause.

Officials from South Bend and the state of Indiana said there was not enough evidence to support a single cause of the January house fire that killed six children.
