Stockton police are treating the death of a 2-year-old boy as a homicide investigation.

The investigation began Tuesday when police received a phone call from Pleasanton police who began investigating the death of the boy on Oct. 8.

Pleasanton police reported family brought the child to a medical facility on Oct. 7, where the child would later be pronounced dead.

Pleasanton police’s investigation revealed the incident may have happened in Oakland. However, when detectives began working with Oakland police, investigators were led to a home on Diamond Oaks Street in Stockton on Oct. 8, police said.

Stockton police detectives are now leading the investigation to determine what exactly led to the child’s death.
