Google searches are giving more insight into the relationship between admitted Colorado killer Chris Watts, and his mistress, ranging from wedding dresses to book deals.

According to investigative reports, Nichol Kessinger spent two hours looking for wedding dresses, one week before Watts killed his pregnant wife, who is from Clifton, and their daughters.

Kessinger was apparently convinced Watts planned to leave his family.

The final Google searches noted by investigators came after the murders, and included how much money Amber Frey made on her book deal.

Frey is the mistress of convicted killer Scott Peterson.
