When firefighters arrived, the house was engulfed in flames. Pardo had sprayed racing fuel, intending to ignite it with a flare. But flames in two fireplaces triggered an explosion. Killed along with Sylvia were her parents, her two brothers and their wives, her sister and her 17-year-old nephew. The 8-year-old niece, shot in the cheek, survived. Thirteen young people were orphaned.
As the house burned, a neighbor saw a blue car drive away with its headlights off. A pair of fake glasses and Santa's cap had been dropped in the frontyard.
Pardo drove 40 miles to his brother's home in Sylmar. He had second- and third-degree burns on his arms, hands and the back of his neck. He also had leg burns; his Santa suit had melted into his skin. A clean getaway was no longer an option.
When Pardo's brother returned home at 3:10 a.m., he found Pardo's body sprawled on the living room couch, two handguns by his side. He had shot himself in the mouth. He was still wearing his wedding ring.
Brad Pardo dialed 911.
