Investigators say a Staten Island mother and son who died in a suspected murder-suicide and arson had ingested some type of drug.

Two law enforcement officials told The Associated Press on Monday there were traces of drugs in the bodies of Leisa Jones and her 14-year-old son. The officials spoke on condition of anonymity because further tests were pending.

Police are trying to determine whether the mother — who penned a charred note found in the apartment saying “am sorry” — or the teen caused the five deaths in a torched Staten Island apartment.

Jones, her son and two young daughters — their throats slit — were found dead early Thursday after firefighters responded to the blaze. A 2-year-old boy died at the hospital of smoke inhalation.
