On
Big Brother, Jasinski was paired with
Sheila Kennedy. Jasinski won part two of the three-part final "Head of Household" competition. At the finale, Jasinski became the winner of
Big Brother 9 by a vote of 6–1, defeating fellow houseguest Ryan Quicksall and earning the $500,000 prize. Jasinski received votes from Matt McDonald, Chelsia Hart, James Zinkand, Natalie Cunial, Sharon Obermueller, and Sheila Kennedy. Jasinski only lost the vote of Joshuah Welch. Afterwards, Jasinski said "If only if they knew how easy it was to win it all! I would love to do it all over again and really share with the diary room and America my strategy. I was very skeptical, therefore, held back from everyone watching what I was truly up to." ==Criminal activity==
