An Ohio man will be arraigned on an attempted murder charge in the shooting of his wife in a hospital intensive care unit.

Akron police said John Wise, 66, of Massillon entered his wife Barbara's hospital room Saturday and shot her while standing at her bedside. He will be arraigned on Monday.

Capt. Dan Zampelli told the Akron Beacon Journal that the shooting may have been an attempted mercy killing.

"It seems to be slanting that way. He wanted to take away her suffering," Zampelli told the newspaper.

Barbara Wise, 65, remained in critical condition late Sunday at Akron General Medical Center.

Jim Gosky, a spokesman for the medical center, said one shot was fired and security officers reached the ICU in about one minute. A doctor was in a nearby room.

Gosky said privacy rules prevent release of details why Wise had been admitted to the ICU a few days earlier.
