TOLEDO, Ohio - The county coroner's office in Toledo says three children who died of carbon monoxide poisoning in a suspected murder-suicide had no drugs in their systems.
A Lucas County deputy coroner said Wednesday no irregularities turned up in toxicology tests for the three siblings, ages 5, 7 and 10. They were found dead in a Toledo garage in mid-November, along with their grandmother and uncle.
Police said notes indicated the two adults planned to kill themselves and the children by funneling fumes from a truck into the car where their bodies were found. There were coloring books and food in the vehicle, and investigators found no signs the children were forced inside.
Police and family friends said the murder-suicide apparently stemmed from a family disagreement over where the children should live.
