MIAMI (CBSMiami/AP) — Testimony wrapped up Friday afternoon in the trial of a man dubbed the Facebook killer.
Derek Medina, 33, claims he shot his wife in self-defense before posting a photo of her dead body on Facebook.
The testimony Friday in the trial focused on forensic evidence and police crime scene experts.
The lead detective on the case, Jonathan Grossman, testified that Medina was calm and collected when he gave a videotaped interview after killing his wife.
In the interview, Medina said "I am not a killer.It was self-defense."
Earlier, a defense attorney pulled out and showed jurors a knife Medina's wife, 27-year-old Jennifer Alfonso, presumably pulled on him.
They also pulled out the gun Medina allegedly used to kill Alfonso.
Miami-Dade Police Crime Scene Technician Yvonne Garcia also took the stand and explained how she directed her team to review the evidence in the case.
Before that, another crime scene technician, Anabella Pasqua, explained how they read the blood splatter from the incident to predict the angle at which she was shot. State prosecutors argue that Alfonso was cowering on her knees when Medina shot her. Defense attorneys counter that theory saying she fell backwards after she continued her attack on Medina.
Medina faces a maximum life prison sentence if convicted of murder in the August 2013 killing of Alfonso.
Defense attorneys say their self-defense claim centers on evidence that Alfonso abused drugs, battered her husband and was involved in Satan worship. Prosecutors say Medina was a boxer who could overpower her but shot her because she threatened to leave him.
Medina told police he uploaded a photo of Alfonso's body on Facebook to show family what had happened.
Alfonso's mother sat in the middle row of the courtroom and at times appeared teary-eyed when photographs of her daughter's body were shown to jurors.
