California mother arrested after toddler dies from fentanyl overdose

A California mother has been accused of child endangerment after her 3-year-old son died from a fentanyl overdose earlier this year, police said Thursday.

On May 4, police received a call about an unresponsive child who was turning blue and not breathing in a San Luis Obispo home. The fire department began life-saving efforts and took the child to the hospital, but he never regained consciousness and was pronounced dead that evening.

San Luis Obispo police launched an investigation into the child's death and performed a toxicology report. The results, which arrived in mid-June, indicated that the child had a high level of fentanyl in his system, the police report said.
