TOLEDO, Ohio - An ailing Roman Catholic priest convicted of killing a nun is asking a judge to let him come home to Toledo to die.

An attorney for Gerald Robinson filed a motion in federal court Friday seeking "an act of grace for a dying man." The 76-year-old Robinson could possibly spend his final days in the care of nuns who have agreed to take him in.

Robinson is in a prison hospice unit in Columbus.

The (Toledo) Blade reports that his attorney on June 2 sent a letter to the governor requesting Robinson's release from prison after learning that Robinson had suffered "a massive coronary" and was terminal. But that request was denied.

Robinson was convicted in 2006 of killing Sister Margaret Ann Pahl during Easter weekend in 1980.
