The Mysterious February 2010 Disappearance

Timeline of Events

In early February 2010, Joseph and Summer discussed plans to take the boys on a weekend camping trip. After withdrawing cash, purchasing camping gear, and arranging childcare, the family vanished without leaving clear explanations or traces.

Security camera footage from their Rancho San Antonio store showed Joseph and Summer calmly closing up shop, while subsequent footage revealed an unauthorized ATM withdrawal using Joseph’s card days later.
