AUGUSTA -- A jury has found John A. Okie guilty of two counts of murder for killing a former girlfriend and his father in July 2007.

The Kennebec County Superior Court Jury took less than three hours to return the guilty verdict. Sentencing is scheduled for January. Okie could be sentenced for up to 25 years to life imprisonment for each count.

Okie's lawyer, Peter DeTroy, acknowledged on the first day of the trial that Okie, 22, killed Alexandra "Aleigh" Mills, 19, and John S.Okie, 59, six days apart that summer.

DeTroy argued that Okie suffered from paranoid schizophrenia and was not criminally responsible when he beat Mills to death in her Wayne home with a wooden post and then stabbed his father to death at the Okie home in Newcastle.

Prosecutors, meanwhile, successfully argued Okie knew he was committing a crime when he killed the two and should be found guilty of two murders.
