A homicide investigation is underway in Montgomery after a 6-month-old boy died in a Birmingham hospital of injuries he sustained earlier this month, authorities said Tuesday.

Montgomery police were notified Nov. 7 about a 6-month-old boy with life-threatening injuries who had been taken to a hospital in Birmingham, said Maj. Saba Coleman.

The boy was pronounced dead on Nov. 10, said Coleman. His body was taken to the Alabama Department of Forensic Science for an autopsy.

The circumstances of the child’s death were not initially known, which prompted a death investigation.

New information determined the boy was the victim of a homicide, Coleman said.

Further details about how the child was injured or about the case were not released.

Anyone with information that would be helpful to the investigation was asked to call CrimeStoppers at 334-215-STOP, Secret Witness at 334-625-4000, or Montgomery police at 334-625-2831.
