CELL TOWER TRACKING EXPERTS

Michael Cherry and Manfred Schenk are the only experts to have ever won Innocence, Habeas or Dauberts against Historical Cell Site Analysis / Cell Tower Tracking. Lisa Roberts is free after 12 years in jail.

 

Mike and Manfred,

Lisa Roberts was released yesterday afternoon.  The DA will not
attempt to prosecute the case again. Thank you so much for your
work on this case. It was pretty amazing to be there to pick up Lisa
at the prison gate as she was released after serving 12 years for a
crime she did not commit. Cheers, William

The strongest tower / nearest tower nursery rhymes are only nursery rhymes. Per Call Measurement Data (PCMD) is unfortunately also misunderstood and misinterpreted. 

Michael and Manfred met when they were both working on Apollo 11 The Trip To The Moon. They are mainframe, SCADA and PC assembly language programmers who design and live communications network products and solutions. The New Yorker Magazine and The Washington Post have both written cell phone tracking articles:

UNITED STATES v. ANTONIO EVANS

After listening to the defense testimony, Judge Joan Lefkow concluded that the prosecution testimony was unreliable.  In her words,

[The prosecution expert, FBI CAST] Special Agent Raschke testified that using a theory of granulization he can estimate the range of certain cell sites based on a tower’s location [relative] to other towers.  This in turns allow him to predict the coverage overlap of two closely positioned towers.  Special Agent Raschke testified that he has used this theory numerous times in the field to locate individuals in other cases with a zero percent rate of error.

Judge Lefkow was “unconvinced that [the prosecution’s] granulization theory is reliable.”  She found that the theory “remains wholly untested by the scientific community.” Her Honor commented that “[e]stimating the coverage area of radio frequency waves requires more than just training and experience;  it requires scientific calculations to take into account factors that can affect coverage.  Special Agent Raschke presented no scientific calculations and did not consider a variety of relevant factors.”  In her ruling, she excluded both part of Agent Raschke’s testimony and a chart purportedly estimating the range of coverage of the cell towers involved in the case.
