Sam Weaver was a real estate agent and the uncle of Holly Weaver.
When Holly was a kid she lived with her uncle Sam. Sam was secretly a pedophile and he sexually molested her everyday she lived with him. Holly would later tell Tommy Egan all this when they started dating. After leaving Chicago while on a business trip Tommy spots a sign to Cleveland and decides to confront Sam. Sam is a real estate agent and Tommy spots him entering one of the houses he is trying to sell. Tommy meets him inside and confronts Sam with what Holly told him.

Tommy then leaves the scene of the crime after killing Sam.
