The remaining members of that family now are in mourning, after a Christmas Eve attack on the Ortegas' home by the vengeful ex-husband of one of their daughters, Sylvia Pardo.

Bruce Pardo donned a Santa Claus suit and killed nine members of the Ortega family during the Christmas party where the close-knit family gathered each year, before spraying the home with racing fuel that set it on fire. Pardo later killed himself.

"They really were a great family," said Jose Castillo, Sylvia Pardo's brother-in-law from an earlier marriage, who came to pay his respects Sunday at the end of a quiet cul-de-sac where the Ortegas' two-story home once stood. "They used to be together all the time."

Joseph Ortega, 80, and Alicia, 70, had retired about 10 years ago from their business painting metal furniture and other items in nearby El Monte.

The couple immigrated to the United States shortly after their marriage 53 years ago in the Mexican city of Torreon, that city's newspaper, El Siglo de Torreon, reported Saturday.

The family is well-known in the city, where Alicia's sisters are prominent businesswomen, the newspaper's editorial director Javier Garza told the Los Angeles Times.

Sylvia Pardo, 43, had been living at her parents' home since her divorce from Bruce Pardo, a 45-year-old electrical engineer, about a year ago, Castillo said.

Her earlier marriage to Jose Castillo's brother, Sabino Castillo, ended with Sabino's death in a traffic accident about 20 years ago, when she was pregnant with their youngest of two children.

Both children, a 21-year-old daughter and 20-year-old son, had escaped unharmed from the party where Bruce Pardo opened fire.
