A mobile crime scene · one survivor · two convictions
A survivor's identification and an active federal warrant led investigators to James Daveggio and Michelle Michaud soon after Vanessa Lei Samson was abducted and killed.
The Daveggio-Michaud minivan murders case centered on a 1997 series of kidnappings, sexual assaults, and murder carried out in California and Nevada by James Daveggio and Michelle Michaud using a specially modified Dodge Caravan. The case was solved after the abduction, torture, and killing of Vanessa Lei Samson led investigators to the pair, and it remains notable for the deliberate way the minivan was equipped and used as a mobile torture chamber.
