John Pezzenti Jr, 55, was found dead in his Bear Valley home on the 15000 block of Francesca Drive after Anchorage police responded on the morning of Monday, December 3, 2007. Investigators later concluded he likely died sometime between about 7 p.m. on Saturday, December 1, and 1:30 p.m. on Sunday, December 2, suggesting he was alone in the house when he was killed.

A celebrated wildlife photographer whose books and images brought Alaska’s animals to wide audiences, Pezzenti’s death was treated as a homicide from the outset. Detectives released appeals for tips, and the case was publicized on crime-stoppers lists and national television, but no motive matching the evidence was identified and leads remained scarce.

Who knew Pezzenti that weekend, visited his Francesca Drive home, or might have information about anyone seen near the house between the evening of December 1 and the afternoon of December 2?
