A Georgia woman whose teenage son allegedly killed four people at Apalachee High School has been accused of taping her elderly mother to a chair, stealing her phone and damaging her home, according to a report.

She is charged with exploitation and intimidation of a disabled adult or elderly person, false imprisonment, criminal damage to property in the second degree, and theft.

The mistreatment took place on November 3, after Marcee insisted that Polhamus join her in confronting her ex, Colin Gray, during a heated altercation, according to authorities.

Brown told police she had become concerned about her mother after she was unable to reach her by phone, and had asked her friend, who lives in Fitzgerald, to check on her. Gray, 43, was indicted Monday on single counts of exploitation and intimidation of a disabled adult or elderly person,

The mother of accused Georgia high school shooter Colt Gray, was previously arrested on accusations of taping her elderly mother to a chair, stealing her phone and damaging her home, according to an incident report obtained by the Atlanta Journal Constitution.
