The Clark County coroner’s office has determined that a 19-month-old girl, whose death in April prompted a Las Vegas police investigation, died of an accidental drug overdose.
Heroin, fentanyl and acetyl fentanyl intoxication killed Myla Byrne on April 13 at Sunrise Hospital and Medical Center, the coroner’s office ruled Friday.
About 12:50 p.m. that day, Las Vegas police were notified of an unresponsive child inside a home at 6555 Boulder Highway, near Russell Road.
No arrests had been made in Myla’s death as of Friday. Police spokeswoman Alejandra Zambrano said the investigation was ongoing.
A Clark County Division of Family Services death report shows that Myla’s family has a history with Child Protective Services dating to April 2016, before the girl was born. That 2016 investigation was opened after Child Protective Services received a report of abuse and neglect.
The allegations were found to be substantiated, the report says, but for unspecified reasons, the family “was not in need of referrals nor services.” The case then was closed.
A previous version of this story incorrectly stated the date of Myla Byrne’s death.
