Hainstock is currently serving his sentence at Oshkosh Correctional Institution after previously being incarcerated at the Green Bay Correctional Institution in Green Bay, Wisconsin. While in prison, he has allowed Isthmus to share his story. He has written a ten-page letter with the help of his cellmate. According to Hainstock, he has gained 50 pounds, his reading went from a fourth-grade level to a tenth-grade level, and he is working on his GED. Hainstock's father and stepmother Priscilla visit him about every month. In his letter, Hainstock takes responsibility for what he did, but he believes that he is not to blame for everything. In October 2008, Hainstock's supportive cellmate at Green Bay was reassigned without any official explanation.
