with respect to the casings, no fingerprint evidence linking those casings to mr. serrano? that s right. no serrano fingerprints found anywhere around the crime scene. not a single fingerprint was linked to mr. serrano in that building, isn t that true? none of the fingerprints were linked to him. the dusty shoe print seemed to be serrano s shoe size. can you tell me how many shoes there are that match no, i cannot. 2 million, 10 million, 100 million? do you know? i really don t know. this is all part of a circumstantial case. you have to believe each link in the chain to get him to make that footprint in the chair. what is the theory here, there are three men in there, 200 plus pounds each. excuse me, fellas, i need to borrow this chair so i can climb up there and get a gun and shoot you with it.
