Police say they charged a Pennsylvania man with public drunkenness after he was seen trying to resuscitate a long-dead opossum along a highway.

State police Trooper Jamie Levier says several witnesses saw 55-year-old Donald Wolfe near the animal Thursday along a highway about 105 kilometres northeast of Pittsburgh.

The trooper says one person saw Wolfe kneeling before the animal and gesturing as though he were conducting a seance. He says another saw Wolfe attempting to give mouth-to-mouth resuscitation.

Levier says the animal already had been dead a while.
