Homicide

Court Opinion: This case involves the admission of testimony regarding forensic science, crime reconstruction and motive. I was qualified and allowed to testify in each of these areas from 10/02-10/03/06.

Outcome: This was a retrial. Lobato was originally convicted of first-degree murder and sexual penetration of a corpse for Duran Bailey's murder on May 18, 2002.

The Nevada Supreme Court granted her a new trial in September 2004, citing the trial judge's failure to admit evidence that could have weakened the credibility of a jailhouse informant.

In October of 2006, despite any physical evidence or witnesses, she was found guilty of the lesser offense of voluntary manslaughter with use of a deadly weapon and sexual penetration of corpse.

Homicide

Court Opinion: This case involves the admission of testimony regarding forensic science, crime reconstruction and crime scene staging. I was qualified and allowed to testify in each of these areas from 8/30 - 8/31/06. None of my findings were disputed by the prosecution's surprise rebuttal witness.

Note: Both Asst. District Attorney Manya Creel and my client, Defense Attorney James Gray, were at the time of trial running for judge. This was a vacancy created by Judge Michael R. Eubanks, Circuit Court of Pearl River County who presided over, and retired shortly after, this trial. Judge Eubanks was a no nonsense jurist with very little tolerance for game-playing and the irrelevant.

Crime Scene Staging: July, 2003  

Note: I was contacted by the defense in this case to examine the findings of Charles K. Dorsey. In my report, I detailed how his opinions exceeded the limits of acceptable forensic testimony within the realm of crime scene staging. I also demonstrated how his findings were based on illegimate and inaccurate assumptions, and incomplete information. The day prior to his scheduled testimony, with me waiting to rebut, Mr. Dorsey was removed as an expert witness from the case by the prosecution.

Proffer (includes profile opinion): This is the first known case where a criminal profiler was allowed to offer expert profiling opinions, labeled clearly as such, in court, before a jury, during the guilt phase of a trial. In June of 2000, despite the extraordinary lack of any actual evidence of guilt or circumstances, a Sauk County jury took nine hours to decide that Peter Kupaza killed and then dismembered his 25-year-old cousin, Mwivano Mwambashi Kupaza, sometime in late July 1999. Kupaza was subsequently sentenced to life in prison, having been convicted of both first-degree murder and hiding a corpse.

Testimony: April 4, 2000

Court Opinion: This case involves the admission of testimony regarding victimology, crime reconstruction and false confessions. It also involves a conviction in a case where clear and convincing DNA evidence exonerated the defendant! Not sure how this conviction happened...
