Indiana's state fire marshal says an investigation into a northern Indiana house fire that killed six siblings in January failed to determine what caused the deadly blaze, although electrical items were identified as "potential ignition sources.

Investigators spent thousands of hours looking into the fire, which destroyed a South Bend home on Jan. 21, 2024.

Investigators with the Indiana State Fire Marshal's Office announced Wednesday that the cause of a fire that killed six children in South Bend in January of 2024 may never be determined.

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.

What caused the tragic fatal fire on 222 N. LaPorte Ave. nearly one year ago? South Bend will provide updates in the investigation on Dec. 11.

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.

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.
