A Santa Clara County Superior Court judge says that he warned prosecutors and San Jose police years ago against using phony crime lab reports as a ruse during interrogations - long before the recent controversy that forced police to disavow the practice.
The warning from Judge Ray Cunningham, now the presiding judge of the county's criminal courts, is one indication uncovered this past week that the police use of the phony reports during questioning of sex crime suspects was more extensive than previously known. Cunningham said the case dated to the 1990s. In a separate 2002 case, detective Juan Serrano described the use of ruse crime lab reports as "standard procedure" at that time.
Further, as Cunningham's comments reflect, the practice had drawn concern long before detective Matthew Christian falsely testified last year that a crime lab report implicated Michael Kerkeles as having sexually assaulted a developmentally-disabled woman who lived nearby. The charges against Kerkeles were dropped last year once his attorney asked for the resume of Rebecca Roberts, the name on the crime lab report - and learned she was a fictional character and the report had been concocted by Christian.
Police and prosecutors have since accepted Christian's explanation that he forgot he had earlier created the report to try to win a confession from Kerkeles.
False DNA report
Police detectives also created a false report bearing the name of fictional analyst Rebecca Roberts when they convinced Marino Hernandez in 2002 to give a DNA sample that linked him to a series of sexual assaults, court records show.
Serrano's partner, Todd Trayer, testified that he had invented Roberts' name when he created the false report for questioning Hernandez. Trayer told the court that he entered information into a "boilerplate faux DNA sheet" that was used in the sexual assaults unit, printed the form out and took it to his interview with Hernandez.
The form appears authentic, bearing the seal of the county district attorney, which operates the lab.
