Police say an elderly couple found alive with knife wounds in their Pennsylvania home had a suicide pact and the man could now face criminal charges.

The two were discovered Sunday afternoon in Belle Vernon.

Rostraver police say the 80-year-old man told them he slit the throat of his 82-year-old wife, then swallowed 20 painkillers and cut his own wrists.

Police Chief Greg Resetar says it's not clear why the couple would have made the pact. He says there are no known health issues that would have prompted it.

The woman is in in critical condition at a hospital. The man was recovering in fair condition at a different hospital.
