LAPD detectives are investigating the death of a toddler in Porter Ranch as a possible drug overdose after law enforcement sources told NBC4 Investigates drug paraphernalia was discovered in the boy’s home, and the father made references to fentanyl in conversations with emergency responders.

According to the sources, the boy was found unresponsive when someone tried to wake him from a nap, and the father allegedly told paramedics he hoped the boy “did not get into his fentanyl.”

The boy died at a hospital April 3 after paramedics transported the boy to the hospital in what was described as, “grave,” condition.

The boy lived in a home near Rinaldi Street and Wilbur Avenue, according to police.

The Los Angeles County Department of Medical Examiner was conducting lab tests to determine an exact cause of death, according to an entry in its case tracking system.

Detectives questioned the father and released him while they continue to investigate what happened.

The sources said ‘evidence of drug use’ and paraphernalia were found inside the home.
