Fridley man indicted in thallium poisoning death

Stuart Hanmer, 35, a Fridley resident, was indicted by a grand jury on a count of premeditated first-degree murder and faces an existing second-degree murder charge after his roommate Cody Ernst, 33, died of thallium poisoning. Court records say Ernst fell ill May 15, was hospitalized and died June 22; prosecutors cite internet searches and three purchases of thallium found in connection with Hanmer, and bail was raised to $5 million without conditions ($2.5 million with conditions). Hanmer remains in custody at the Stearns County Jail pending further court proceedings.
