An elderly Vallejo crime witness who was ambushed and fatally stabbed could be tied to multiple coast-to-coast deaths, including a Border Patrol agent.

The suspects involved in the fatal shooting of Border Patrol Agent David Maland may be tied to a radical, vegan and transgender cult.

Investigators believe a radical "death cult" known as the "Zizians" could be behind the January killing of a Vermont Border Patrol agent. Authorities say the group could be linked to at least five other deaths across the country dating back to 2022.
