Authorities say a woman who provided hacksaw blades, chisels and other tools to two convicted murderers who escaped from a maximum-security prison discussed having them kill her husband.

Clinton County District Attorney Andrew Wylie says Joyce Mitchell talked to inmates Richard Matt and David Sweat about killing her husband, Lyle, who also works at the Clinton Correctional Facility in Dannemora.

Sweat and Matt escaped from the prison June 6. They have yet to be apprehended. Joyce Mitchell, a prison tailoring shop instructor who befriended the inmates, was arrested June 12.

Meanwhile, state police expanded the search for the killers beyond a 16-square-mile area of woods, fields and swamps where the manhunt has been most intense. They're checking seasonal homes and hunting camps and have increased roving patrols.
