CHATTANOOGA — The Chattanooga Police Department arrested Leah Duncan in connection with a homicide at a Manor Road residence. Duncan is the second suspect arrested in connection with the homicide.

The arrest took place on Tuesday. Duncan is 29 years old. Authorities charged her with felony murder, especially aggravated robbery, and tampering with evidence.

The underlying homicide occurred on Thursday, July 16, 2026. The incident took place at a residence on Manor Road. Police have not released further details regarding the specific circumstances of the death during this initial reporting period.

Following the arrest, Duncan was taken into custody. She is currently being held at the Hamilton County Jail and Detention Center. The charges stem from the investigation into the July 16 incident that left a victim dead at the Manor Road location.

This arrest marks a significant development in the investigation into the July 16 homicide. With Duncan being the second suspect taken into custody, law enforcement has expanded the scope of individuals they believe were involved in the crime. The charges of felony murder and especially aggravated robbery indicate the severity with which prosecutors are viewing the case.

The inclusion of a charge for tampering with evidence suggests investigators believe actions were taken to obstruct the inquiry into the death. Duncan remains in custody at the Hamilton County Jail and Detention Center as the legal process begins. The case continues to draw attention in Chattanooga as authorities work to establish the full sequence of events surrounding the Manor Road homicide.
