CLEVELAND: Fire investigators say a heavily damaged home where two children and two adults are missing after an overnight fire in Cleveland is too dangerous to search.

A fire department spokesman says construction equipment will be used to take apart the home and make it safe for firefighters to search inside.

He says search crews will be careful not to disturb any potential evidence that could help determine what caused the fire.

Firefighters say a woman believed to be the children’s mother escaped by jumping from a second floor window early Tuesday morning.

Investigators say a 4-year-old boy, an 8-year-old girl, their father and another man are missing.

The fire department spokesman tells Cleveland.com that the woman who survived said she tried but couldn’t get to her children.
