Correction:

Earlier versions of this story gave the wrong middle initial for former federal prosecutor Michael R. Bromwich.

Convicted defendants left uninformed of forensic flaws found by Justice Dept.

But the private lab’s DNA tests irrefutably showed that the 13 hairs came from three human sources, each of African origin, except for one — which came from a dog.

“Such is the true state of hair microscopy,” Levick wrote. “Two FBI-trained analysts, James Hilverda and Harold Deadman, could not even distinguish human hairs from canine hairs.”

Convictions linked to suspect forensics

Hilverda declined to comment. Deadman said his role was limited to describing characteristics of hairs he found.

Kirk Odom’s case shares similarities with Tribble’s. Odom was convicted of raping, sodomizing and robbing a 27-year-old woman before dawn in her Capitol Hill apartment in 1981.

The victim said she spoke with her assailant and observed him for up to two minutes in the “dim light” of street lamps through her windows before she was gagged, bound and blindfolded in an hour-long assault.

Police put together a composite sketch of the attacker, based on the victim’s description. About five weeks after the assault, a police officer was talking to Odom about an unrelated matter. He thought Odom looked like the sketch. So he retrieved a two-year-old photograph of Odom, from when he was 16, and put it in a photo array for the victim. The victim picked the image out of the array that April and identified Odom at a lineup in May. She identified Odom again at his trial, telling jurors her assailant “had left her with an image of his face etched in her mind.”

At trial, FBI Special Agent Myron T. Scholberg testified that a hair found on the victim’s nightgown was “microscopically like” Odom’s, meaning the samples were indistinguishable. Prosecutors explained that Scholberg had not been able to distinguish between hair samples only “eight or 10 times in the past 10 years, while performing thousands of analyses.”

But on Jan. 18 of this year, Melton, of the same lab used in the Tribble case, Mitotyping Technologies of State College, Pa., reported its court-ordered DNA test results: The hair in the case could not have come from Odom.

On Feb. 27, a second laboratory selected by prosecutors, Bode Technology of Lorton, turned over the results of court-ordered nuclear DNA testing of stains left by the perpetrator on a pillowcase and robe.

Only one man left all four partial DNA profiles developed by the lab, and that man could not have been Odom.

The victim “was tragically mistaken in her identification of Mr. Odom as her assailant,” Levick wrote in a motion filed March 14 seeking his exoneration. “One man committed these heinous crimes; that man was not Kirk L. Odom.”

Scholberg, who retired in 1985 as head of hair and fiber analysis after 18 years at the FBI lab, said side-by-side hair comparison “was the best method we had at the time.”

Odom, who was imprisoned for 20 years, had to register as a sex offender and remains on lifelong parole. He says court-ordered therapists still berate him for saying he is not guilty. Over the years, his conviction has kept him from possible jobs, he said.

“There was always the thought in the back of my mind . . . ‘One day will my name be cleared?’ ” Odom said at his home in Southeast Washington, where he lives with his wife, Harriet, a medical counselor.
