For many, the "M" in Montecito is for millionaires, mansions, and moguls, but there is a seamier side to the exclusive California enclave, where "M" stands for murder, manslaughter, madness, and multiple other misdeeds.

Here is a history of the homicides of Montecito, from a 19th century slaying of a mother and child that made headlines across the country to the mid-20th century, with killings by hit men, jealous husbands, abused wives, and a terrorist.

A macabre treat for the reader of true crime and those interested in Montecito history.
