JACKSONVILLE, Fla. – A forensic serologist was the first witness called Monday morning in the ongoing Michael Dunn trial.
Sukhan Warf, a DNA analyst with the Florida Department of Law Enforcement, was called to the witness stand just after 9 a.m. Monday. Assistant State Attorney John Guy questioned Warf on her education, background and experience in analyzing body fluids and touch DNA. During Guy's questioning, Warf was officially recognized as an expert in her field by the court.
Warf was asked to explain what items she analyzed from the crime scene at the Gate gas station on Southside and Baymeadows collected November 2012.
Multiple swabs from 9mm shell casings were received by FDLE, according to Warf's testimony. Warf stated she took a cutting from a swab and subjected it to the DNA testing process, however results showed there was not DNA found on the casing Warf analyzed. Warf explained it is common to not find DNA on casings.
During cross examination by Dunn's attorney Cory Strolla, Warf was questioned on the types of analysis she performed and why. Warf explained that only a touch sample was performed on the shell casings and that not all shell casings recovered were tested.
The reasoning was that the three additional casing were recovered from Dunn's car and her role is to, "tie people together or tie people to scene" and "something in their own possession doesn't seem to help.
Strolla wrapped up questioning and the next witness was called by the State Attorney's Office, Maria Pagan. Pagan is also from the Florida Department of Law Enforcement and works as a crime lab analyst in firearms.
State Attorney Angela Corey questioned Pagan on her education, background and service with the Florida Department of Law Enforcement. During questioning, Pagan was recognized by the court as an expert in firearms and ammunition identification.
Pagan explained and demonstrated with Dunn's gun to jurors how firearms work, specifically the gun belonging to Dunn. In Pagan's opinion, the safety on Dunn's gun did not operate as smoothly as it should.
Pagan also testified that Dunn's gun has six grooves and a right twist. She also stated the bullet jackets recovered from the crime scene were not marked well, but that the bullets did have the correct grooves and right twist with a similar width to Dunn's gun.
During cross examination by Strolla, Pagan was asked if she researched who owned the gun prior to Dunn. Pagan explained to Strolla, that it was not her role, but did say the gun did not appear to be altered and functioned as it was designed to.
