Cellmark CACLD Errors

There were two different proficiency tests administered by the California Association of Crime Lab Directors in 1988 and 1989. Cellmark made one false match in each of these tests. These false positives are discussed in more detail in a paper by W. Thompson and S. Ford [In: Forensic DNA Technology (Proceedings of the American Chemical Society, Science and Law Conference, Los Angeles, CA, 1988), M. Farley and J. Harrington (eds), Lewis Publisher, Chelsea, Michigan].
