Shawnee County District Attorney Robert Hecht filed formal charges Thursday in Topeka's latest homicide.
27-year old Sterling Hall III, also known as Sherman Hall, faces counts of first degree premeditated murder and criminal possession of a firearm.
Authorities say Hall shot 50-year old Pamela McMaster four times in the back outside her room at the Regency Inn on South Topeka Boulevard on May 15th. Hecht says the investigation hasn't established any relationships between McMaster, Hall or the man McMaster was with, her fiance Michael Scroggins.
Hecht says the firearms charge stems from Hall's previous conviction of drug possession in Dickinson County.
He's being held on $350,000 bond.
