What strange events did the townspeople blame on Boo Radley?

The Radleys are also differentiated from the community by their willful isolation from the usual patterns of social interaction, which causes the town to ostracize them and unreasonably turn the mysterious Boo into a scapegoat for any odd and unfortunate circumstances that occur. For instance, when various domesticated animals are mutilated and killed, townspeople still suspect Boo even after Crazy Addie is found guilty of this violence.

To the children, Boo is only what they have heard from popular legend, and interpreted in their own imaginations. Scout's retelling of Jem's description of Boo shows how her young mind could not yet distinguish between fact and fiction. Jem explains that Boo, "dined on raw squirrels and any cats he could catch, that's why his hands were blood-stained - if you ate an animal raw, you could never wash the blood off." The children's acceptance of such superstitions as the permanence of raw animal blood shows that they are equally susceptible to accepting the local gossip about the mysterious Boo, as evidenced by Scout's evaluation of Jem's description as "reasonable."
