Family members gathered in Harlem for the funeral services of the 2-year-old boy who police say was thrown into the Bronx River by his father last month.

It was a somber day for the family of Montrell Williams. It was an intimate service with a closed casket as they said their last goodbye's to the toddler.

Montrell's body was carried out of the First Avenue Funeral Home Saturday morning, just one day after his 17-year-old mother graduated from high school. Her son was supposed to be there to celebrate with her.

Prosecutors say Montrell was still alive when he was apparently thrown into the river by his 20-year-old father – Arius Williams – on May 10. His body was pulled from the East River near Ferry Point Park on June 11.

Williams was charged with two counts of murder and two counts of manslaughter. He pleaded not guilty to the charges.

Members of Montrell's family – including the 2-year-old's mother – allege that they tried to alert police about the toddler's disappearance several weeks before his body was found.

The family wants to change the process to report missing children, so this doesn't happen again. They hope to name a street after Montrell Williams so his memory lives on.
