An Italian couple have confessed to killing four neighbors, including a toddler, after a feud over noise, a prosecutor said.
Raffaella Castagna, 30, her 2-year-old son, her mother and a neighbor were found with their throats slit Dec. 11 in Castagna's apartment in the wealthy northern town of Erba. The home had been set on fire.
This week police arrested Olindo Romano and Rosa Bazzi, a middle-aged couple with no criminal record who live in the same building. They had a long-running feud with the Castagnas, whom they accused of being noisy.
