Kellyane Tonyebell

Kellyane Tonyebell, a one-month-old black girl, died Friday, March 4, of a drug overdose in the 13000 block of Los Angeles Street in Baldwin Park, according to the Los Angeles County coroner’s office. 

At about 5:30 a.m., the girl's mother saw that the baby was not breathing, according to L.A. County Sheriff's Lt. Joe Mendoza.

The mother then attempted CPR and called 911. Paramedics took the girl to a hospital where she was pronounced dead at 6:28 a.m., according to coroner’s records. 

The cause of death was not clear at the time, Mendoza said. In late June, deputies received the toxicology report from the coroner; it said Kellyane died of an antihistamine overdose.

Detectives are trying speak to the mother, but Mendoza said she is out of the country.
