Zach Young’s buried toy chest held the secret of Mary Alice’s suicide, explained Paul Young’s suspicious behavior – and held the key to the darkest mystery of Wisteria Lane. Unearthed in the first-season episode “Suspicious Minds” (pictured above), police  found the toy chest dumped in a lake – and inside they found the dismembered remains of a woman. Viewers would later learn the identity of the woman is Diedre, the birth mother of Zach, who was killed by Mary Alice during scuffle when she tried to reclaim the boy. That same toy chest featured in the episode – a pivotal moment in Desperate Housewives – is now available at VIP Fan Auctions.
