MIDDLETOWN, N.Y. - A councilwoman found a severed horse’s head in her swimming pool Tuesday, state police said. “We’re looking at a threat as a possible angle,” Lt. Pierce Gallagher said. “Certainly, we can’t rule that out.” There have been some prior instances of harassment directed toward Wawayanda Councilwoman Gail Soro, Gallagher said. One of the most famous scenes in “The Godfather” showed a movie mogul waking up with a horse head in his bed after he refused to bow to the will of the title character, played by Marlon Brando. Wawayanda is located 106 miles southwest of Albany.
