EAST HAVEN, Conn. — Two children found dead in their homes last month were killed by “acute intoxication” of an over-the-counter antihistamine like Benadryl, the Office of Chief Medical Examiner has ruled.

Their mother has been charged in their deaths inside the East Haven home where the children were discovered, a suicide note left by their mother at their feet. The home had a strong smell of gas, but the actual cause of death, according to the ME, was an “acute intoxication of diphenhydramine,” the substance that is similar to the popular Benadryl brand.

According to WTIC, 6-year-old Aleisha Moore and her 7-year-old brother Daaron were found dead in their home June 2 after a friend of their mother’s called police. That friend said the mother, LeRoya Moore, 36, was threatening to hurt herself and had cuts on her arms. The friend told police children were living with Moore, who had 14 prior convictions and a history with the Department of Children and Families.

Police found Moore’s children inside the house lying fully clothed on a blanket on the floor. Police say they had been dead for some time.

The mom’s letter indicated she was attempting to die with her children: “I know this was meant to end the way it did. I don’t know the reason why, but we were meant to die today. ”

While police searched the home, Moore admitted to turning on the gas. Police said she appeared despondent when she told officers: “I stabbed them, I released them.” However, the medical examiner said blunt force trauma and puncture wounds weren’t the cause of the death.

Moore was taken to the hospital and later put on suicide watch at the Department of Corrections in Niantic. Moore has been charged with two counts of murder and three counts of reckless endangerment. Her children were laid to rest June 16 in Easton.
