(MAY 24, 2023) Two people have been arrested in connection with the stabbing death of Tammey McWilliams, 51, in Great Falls on Tuesday, May 23, 2023.

The Great Falls Police Department said Wednesday evening that Bing Derrick Ahenakew, 20, and Charlotte Mary Andrade, 18, were arrested and charged with voluntary manslaughter.

Cascade County Sheriff-Coroner Jesse Slaughter said an autopsy was performed Wednesday morning in Missoula; the cause of death was multiple stab wounds and the manner of death was homicide.

Officers responded to a “noise disturbance” shortly before 2 a.m. Tuesday near Chowen Springs Park, near the 800 block of South 17th Street.

When officers arrived, they found several people trying to leave the southeast corner of the park, where police found McWilliams' body.

GFPD said “evidence and statements support that some type of physical disturbance occurred” and continues to investigate.

Police stressed this was not a random attack and said there was no risk to the public.

The GFPD added: “Detectives are exploring all possibilities in their investigation prior to any potential charges. Further investigation and evaluation of evidence is ongoing. Detailed information will not be released at this time as it could compromise a full investigation and thorough.”

Anyone with information that could help the investigation is asked to call the GFPD at 406-781-8926.

Bail for Ahenakew and Andrade was set at $500,000 each.
