Source-derived summary

Christian Michael Longo (born January 23, 1974) is an American convicted mass murderer who killed his wife and three children in Oregon in December 2001.

Background

Christian Michael Longo was raised in Ypsilanti Township, Michigan. In 1993, at the age of 19, Longo married 26-year-old Mary Jane Baker and had three children with her. Longo and his family often encountered financial difficulties due to his reckless spending habits.

The Longo family lived in Newport, Oregon. Christian was employed at a local Starbucks, while Mary Jane was a stay-at-home mother. She was also a Jehovah's Witness and active in their local Kingdom Hall. By all accounts, the two devoted their time to raising their three young children. At the time of the murders, the couple had been married for eight years and enjoyed sailing and jigsaw puzzles in their spare time.

Murders

The body of four-year-old Zachary Longo was found on December 19, 2001, in Lint Slough, a backwater of the Alsea River estuary.

Its value is orientation rather than verdict, with Christian, Longo and American providing the first useful test.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
