The two intended to rob the family, but after finding little cash in the house they held the family captive for hours before driving Hawke-Petit to the bank to withdraw $15,000. Hawke-Petit was seen on the bank's surveillance system pleading with the teller to help her family.
Prosecutors alleged that Komisarjevsky raped Michaela, later forcing her to take a shower before tying her to her bed. During Hayes' trial, prosecutors argued that he raped Hawke-Petit before strangling her. As the two girls lay tied to their beds with Hawke-Petit dead on the lower floor of the house, Hayes and Komisarjevsky set fire to the house, prosecutors said, pouring gasoline on and around the girls' bed before fleeing.
