Former detective Robbie Mayer claims police have suspect’s name for Nancy Guthrie case.
Mayer was part of team that investigated ‘Prime Time Rapist’ in the 1980s.
Crime involved Brian Larriva who terrorized Tucson community from 1983 to 1986, sexually assaulting women.
Larriva shot himself when his home was surrounded by police in 1986.
Mayer suggests suspect’s name may be buried among thousands of leads in Nancy’s case.
He believes the suspect’s names are among 50,000 leads and investigators must separate wheat from chaff.
