MARIANNA, Pa. — A man suspected of killing his wife and two young children in their rural western Pennsylvania home was arrested Thursday after a daylong manhunt.

Orlando Maurice Guarino, 38, was charged with three counts of homicide after being captured in Washington, Pa., said state police Capt. Sheldon Epstein.

The arrest brought to an end a search in which authorities surrounded a motel and used electronic billboard messages on highways to ask motorists to look out for a white GMC pickup truck Guarino was believed to be driving. Helicopters also scoured the area.

The bodies of 22-year-old Ashley Guarino, her 2-year-old daughter Dreux and 11-month-old son Orlando Jr. were found by relatives at about 11:30 p.m. Wednesday, authorities said.

Washington County Coroner Tim Warco said it appeared they were asphyxiated, but didn't immediately say how. Warco ruled the deaths homicides, and said autopsies were pending.

Orlando and Ashley Guarino had separated recently, authorities said.

Court documents showed the couple traded abuse allegations last month that resulted in a protection-from-abuse order against Orlando Guarino. Among her allegations, Ashley Guarino claimed her husband had held the boy out the window of a moving vehicle.
