The New York City medical examiner has ruled that the death of a mother who died in a fire with her four children on Staten Island was a suicide.

Spokesman Ellen Borakove said Thursday that autopsy results show that Leisa Jones died from smoke inhalation.

She said that Jones' 14-year-old son, C.J., died from a wound to the neck and his death was ruled a homicide.

Investigators had initially described C.J. as a suspect because he had a history of playing with fire.

Jones' three other children also died in the blaze. Two had their throats cut, and one later died from smoke inhalation at a hospital. C.J. had a razor under his body.

Police have said that a badly damaged, fragmented note with the words "am sorry" that was found was written by Jones.
