My firm has consistently used Johnny Lawrence with BWI in our crime scene investigations. He is knowledgeable and extremely thorough. Jurors find him credible because he puts things in a way folks can accept as the gospel.

CRIME SCENE RECONSTRUCTION AND BLOOD SPATTER ANALYSIS AND INTERPRETATION

On any major case, especially Homicide Investigations, nothing is more relevant than the Crime Scene Investigation. More than most other evidence, the story told by the Crime Scene may be the most compelling. The ability to interpret the information provided by the Crime Scene is crucial to the defense of any defendant charged with a crime. BWI is proud of our association with Johnny Lawrence, perhaps the most qualified Crime Scene Expert in the southeastern United States. In service with the Nashville Metropolitan Police Department for over 31 years, Johnny served as a Homicide Detective for almost 9 years and then as an Identification and Crime Scene Specialist for 14 years. After retiring from the MNPD, Johnny conducted private investigations until joining Berry-Waltz Investigations in 2017. Since Johnny began conducting Crime Scene Reconstruction/Blood Spatter Analysis Investigations for the defense, his success has been unmatched, yielding the following results:

  • 2015 - Expert testimony in Shelby County, Tennessee. Double 1st Degree Murder case. Testified for the Defense in Crime Scene Investigations, Reconstruction, and Bloodstain Pattern Interpretation and Analysis. DISPOSITION – NOT GUILTY all counts:
