(Jerry Nowicki)SPRINGFIELD – The ex-Sangamon County Sheriff’s deputy convicted of murdering Sonya Massey in her kitchen is asking for medical release from a state prison ­– and maintaining that Massey “attacked” him. “To release Grayson under these circumstances would be a miscarriage of justice and an insult to Sonya Massey’s memory and family.” I apologize that he must suffer, but he has to pay for what he did,” Sontae Massey, Sonya Massey’s cousin, told Capitol News Illinois last month. “Grayson’s medical condition and the cost of incarceration were considered – and rejected – by the sentencing judge,” Milhiser wrote.
