-- Fears that gang violence is on the rise in Boston's southern neighborhoods seemed justified as police revealed that Monday's shooting of a five-month-old baby in Mattapan may have been part of a cycle of retaliatory killings between rival Jamaica Plain gangs. Police believe that the shooting, which left Alianna Peguero in the hospital, may have been a retaliation for the April killing of Luis Troncoso on a basketball court in JP. The Troncoso killing, in turn, is said to have been revenge for the death of Peguero's 20-year-old half-brother, Alan Peguero, last September. Police have hit a wall in the investigation, citing the Peguero family's unwillingness to cooperate. Meanwhile, Bostonians wonder when and where the next battle in this gang war will break out.
