it appeared the bottom of the shoe, both shoes, were soaked in blood. reporter: it seemed like damning evidence, but after testing that blood further it came back with two males and two females. reporter: again, nothing you can take to the jury. right. reporter: she tested some of the other evidence, but it didn t lead anywhere. reporter: this is more of jaclyn learning how to be a detective. yes. reporter: she took a week-long course on cell phone investigation taught by a former homicide detective. his name was sy ray, and he was a busy man. i said, hey, i have this case, and it s two years old. and i have this cell phone map and i can t explain it. reporter: one call stood out, an incoming call at 9:01 p.m.
that s what i remember the most. what parts do you remember being red? pants and shoes and a shirt like was bright red. the shirt was white and red? yeah. her shoes. shoes had white laces, and we were tying them. reporter: then, joanna said, daniel, l.j. and v wrapped the unconscious girl in a blue tarp, put her in a white suburban and took off. and when they came back hours later, she said daniel was covered in blood and the girl was not with him. i asked daniel where she was, and he said that she went swimming. he said, she put up one hell of a fight once we got there. reporter: joanna s story rang true, leading derek johnson to believe the mystery girl was annie and daniel ferry was her killer. did you see blood on the carpet? yeah. was it carpet or hard floor? it was carpet.
by neighboring west jordan pd. during her interview, she started telling detectives about a young girl she had seen a week prior. the cops thought some of what she said sounded eerily similar to annie s case. so they called draper pd, and detective derek johnson and his colleague came over to hear what joanna had to say. tell me what you know about this girl. it was the second time i ve seen her over there. reporter: there at the home where a man named daniel ferry used to live. danny ferry is a guy known to law enforcement? yes. reporter: as maybe a drug dealer? drug dealer. he was a member of a gang called vario loco town. and law enforcement has dealt with danny quite a few times, yeah. reporter: ferry had a long rap sheet. in fact, derek had served a search warrant on his home a year earlier. and now here was joanna telling derek that she saw a girl who sounded a lot like annie at daniel ferry s home on the night annie was killed.
can develop your theories about his involvement in this thing? yeah. reporter: they continued to investigate ferry. months went by. lead detective derek johnson was promoted to sergeant. which meant jaclyn moore s case of finally making detective came true. one of her first assignments was the annie kasprzak murder. how did you feel this was going to be your case? i cried for two hours. i cried for two hours. reporter: jaclyn decided she needed to start again from the beginning, following the chain of evidence that led her colleagues to daniel ferry. she thought she might link ferry to annie through his phone calls. but when she checked all of his cell phone records showed he was in the middle to northern part of salt lake county. he had never gone south close enough to where annie was killed. not even near her house. reporter: and she well knew
the physical evidence wasn t there either. none of the dna came back saying annie was ever a friend or ever at his house. detectives never found enough evidence to make a murder charge stick and it turns out there was an explanation. he was also being investigated for an unrelated kidnapping and assault case in a neighboring town. ferry eventually pleaded guilty and was sent to prison. draper police came to believe it was this kidnapping that star witness joanna had recounted to them. she had seen a totally different crime. no way daniel ferry could have committed both crimes. so now, rookie detective jaclyn moore went back to the boxes and binders piled high on her desk. i felt lost. i decided i need to start from the beginning and see what information derek had when he first got the case. reporter: and so began the education of a detective. she started reading through pages and pages of annie s notes and journal entries.
