Prosecution calling up Florida Department of Law Enforcement Analyst Trevor Seifert as next witness.
He does DNA analysis. Is a senior analyst.
He's analyzed well over 8,000 DNA samples and worked on hundreds of cases. He is testifying as an expert in the field of DNA analysis for this trial.
He says DNA is stable in dry and cold environments when it's out in the open on hot, humid, wet or damp environments, DNA degrades rapidly.
He received swabs from inside of the cheeks of Gannon and a card with a blood sample.
Based on the condition of these samples, he could tell it was decomposing body. Wasn't surprised the samples didn't give him enough to make a DNA profile because of how deteriorated Gannon's body was when found. He had to get samples from Gannon's rib bone to do more DNA testing.
Had to go back to the bone, had to break the bone and get marrow. Went back another time and took physical pieces of the bone and did a longer process, with that could get a partial DNA profile.
There was DNA profile for Gannon already created by Metro Crime Lab in Colorado Springs. They matched the DNA profile created with Gannon's rib in Florida.
No cross examination from defense.
