The fourth day of the trial of Frederick Dozier Jr., 32, brought five witnesses to the stand, including two DNA analysts who worked with samples from the victims of three sexual assaults last year.

David Jackson and Mignon Dunbar, both criminalists with the San Francisco Police Department, gave detailed evidence Tuesday on the sample that was collected for one of those three victims.

The criminalists testified for approximately one hour each, describing their qualifications as DNA analysts and the processes they used to compare DNA found at the crime scene to those from Dozier and from swabs collected from one of the women he allegedly attacked.

Both concluded that two types of DNA were found in the victim’s sample, one from the victim and one belonging to a male that matched Dozier’s.

Greg Goldman, Dozier’s public defender, questioned the veracity of the DNA results, inferring that they may have been incorrectly recorded or contaminated. He also questioned whether the results were peer-reviewed.

Other witnesses included Dr. Alina Uzelac, a neuroradiologist at San Francisco General Hospital, and Lucretia Bolin, a family nurse practitioner who specializes in sexual assault injuries.

Uzelac explained that CAT scan of one of the victims showed a fracture of the nasal bone.

“It was a significant blow to the face,” she said, describing to Assistant Attorney Marshall Khine the type of force required to cause that kind of injury.

Dozier, wearing a red-and-white pinstriped button-down shirt, khakis and a tie, did not consult with his attorney until the last witness of the day.

The last witness was SFPD Special Victims Unit Sgt. Joseph Nannery, who assisted in the investigation of the three crime scenes. During questioning, Khine asked Nannery to point at Dozier as someone who had been a “person of interest” to investigators early in the case.

Nannery marked Dozier’s address on a satellite map in reference to the crime scenes. He also testified about a book of mugshots he compiled for one of the victims to review. The victim ultimately chose Dozier’s photo out of 30 in the book, Nannery said.

Dozier spoke with one of Goldman’s interns, who was sitting next to him during the trial, as Nannery testified that he had Photoshopped Dozier’s picture so the background would match the background of the other photographs in the book.

Dozier is charged with 26 felonies in the three attacks. If found guilty, he could be sentenced to life in prison. The trial resumes tomorrow at 9 a.m. in Department 25 of San Francisco Superior Court, 850 Bryant St.
