the suspect, david paul frediani, was a 42-year-old accountant with no prior arrests. since frediani resembled the man helena described, police compared his fingerprints to those found on helena's teapot. they matched. >> one of the things i asked him was -- he had denied even being involved in the initial sexual assault against mrs. greenwood. i remember asking him, you never assaulted this woman? he says, "no, i never did any of that." >> they then told him, we have your fingerprints. at that point, according to detective shapu, frediani took a deep breath, let it out, began trembling. he could actually see his chest moving in and out. and made a statement to the effect as "i was really drunk when i did those things." he then asked for a lawyer and refused to make any more statements. >> at the preliminary hearing where both helena and frediani were present, she was asked if she could identify him and she couldn't. not positively. and out of that arises one of the great mysteries of this whole case. >> but the fingerprints on the teapot were all the prosecution needed
