||In the summer of 2013, three women were sexually assaulted by a masked assailant in the East Side of Bakersfield, CA.
||Biological evidence was collected from three crime scenes. These items included a phone, clothing, a bathtub handle, and zip tie believed to have been used to bind a victim.
||The Kern Regional Crime Laboratory (KRCL) developed DNA data from 37 evidence items.
||Due to the complexity of these low-level 3 and 4 person mixtures, human review of the data was largely inconclusive.
||The computer yielded match statistics from 33 mixture items. 8 of these items linked Johnson to the 3 crimes. Cybergenetics and the KRCL independently obtained concordant TrueAllele match statistics.
||Dr. Mark Perlin testified about the computer's DNA match statistics, giving evidence at a grand jury hearing in December, 2013, and again at Johnson's trial in March, 2015.
||Mr. Johnson was found guilty on 24 charges and was sentenced to life without parole, plus 423 years to life.
