Two people are in custody after police were called for a medical emergency last Thursday in Elk River. 

The Elk River Police Department responded to a call about an 8-year-old girl who was not breathing when officers arrived. 

Efforts to revive the girl were unsuccessful and she was pronounced dead at the scene. 

Sherburne County Sheriff Joel Brott says an autopsy determined that the girl, Autumn Hallow, died as a result of a homicide. Thirty-year-old Brett Hallow and 28-year-old Sarah Hallow of Elk River were arrested Friday evening and are facing second degree murder charges. 

Authorities did not provide any further details at this time. The Minnesota Bureau of Criminal Apprehension assisted in the investigation and future updates on the case will come from the Elk River Police Department.
