During the next few years, Hammer had multiple execution dates set for January 14, 1999, November 16, 2000, February 2001, and June 8, 2004. Weeks before his first execution date, Hammer contacted Sister Camille D’Arienzo, a Sister of Mercy, asking for prayers for him and his victim. Sister Camille traveled from New York to USP-Allenwood with a laicized priest to visit Hammer just 2 weeks from his scheduled execution. Sister Camille became Hammer's spiritual advisor. Once BOP transferred Hammer to USP-Terre Haute, Sister Camille arranged for Sister Rita Clare Gerardot, a Sister of Providence from St. Mary's of the Woods, to visit him on a regular basis. With the support, encouragement and counseling of Sisters Camille and Rita Clare, Hammer found new meaning and devoted his time in prison to help others. Before the Christmas holidays, he created artwork which the Sisters used to create and print holiday cards for sale. The Sisters ensured, at Hammer's request, that the money raised was donated to organizations that helped abused or at-risk youth, and poor and needy children in Haiti and Jamaica. Over several years, Hammer helped to raise $92,000 to help impoverished children like Hammer. Sisters Camille and Rita Clare remained his spiritual advisors and friends.
