Hamilton police say the death of a baby boy last year has been deemed a homicide, but no charges will be laid because the person involved was another child.

Early last year, Hamilton police responded to a 911 call about an “unresponsive infant.”

Paramedics arrived on scene and began performing life-saving measures on the one-year-old boy however they were unable to revive the child.

Police launched a sudden death investigation and the homicide unit was called in to assist as the child was under the age of five.

On March 9, 2022, the Ontario Forensic Pathology Unit determined that the cause of death was blunt-force trauma to the head.

“The Hamilton Police Homicide Unit has completed their investigation and no charges will be laid in this matter as the individual involved is below the age of criminal responsibility,” said police in a news release on Tuesday.

The age of criminal responsibility in Canada is 12, which means anyone under the age cannot be charged.

Hamilton police say they will not be provided any further information about the incident.

The baby’s death brings the number of homicides in Hamilton last year to 20.
