On April 10, 2001, an explosion and fire destroyed the Fisher family home in Scottsdale, Arizona. When the blaze was brought under control, firefighters found the bodies of 38-year-old Mary Fisher and her two children, Brittney, 12, and Bobby, 10, in their beds. Investigators determined the gas line had been deliberately severed and an accelerant used, and autopsies showed Mary had been shot in the back of the head while her children’s throats had been slashed.

Suspicion quickly focused on Mary’s husband and the children’s father, Robert William Fisher. Neighbors reported a loud argument the night before; ATM footage captured Fisher withdrawing cash at 10:43 p.m. with the family’s Toyota 4Runner visible behind him. Ten days later the SUV was found abandoned near Young, Arizona, about 100 miles north of Scottsdale; the family dog was nearby and Fisher was missing.

Fisher was charged with three counts of first-degree murder and one count of arson and was placed on the FBI’s Ten Most Wanted list, yet he has not been apprehended and his whereabouts remain unknown. Did anyone in the Scottsdale area see or hear anything around April 9–10 that could help explain what happened to the Fisher family?
