People of New York v Edward Holley, Sr.
TrueAllele analyzes evidence recovered from car of homicide victim
| Crime | On March 15, 2003, 20-year-old Megan McDonald was found dead with extensive wounds to her head and upper body. Her car was missing. Two days later, a resident of an apartment complex reported that she located McDonald’s vehicle in the complex parking lot. |
| Evidence | Investigators collected evidence from the victim’s vehicle, cell phone, hair tie, and plastic bag. |
| DNA | The New York State Police Forensic Investigation Center developed DNA data from the evidence, including from the victim’s cell phone and driver’s seat cover. |
| Match | The crime laboratory was unable to generate informative results for some items due to incomplete genetic profiles and low quantities of DNA. |
| TrueAllele | On the same data for over 20 evidence items, Cybergenetics performed a free TrueAllele screening, and compared the evidence to over 40 references. Police requested a TrueAllele report on the two evidence items (cell phone and driver’s seat cover) that the computer calculated small inclusionary match statistics to suspect Edward Holley, Sr (53.3 and 23.8, respectively). |
| Cybergenetics | On January 11, 2024, Cybergenetics casework supervisor Bill Allan testified before an Orange County grand jury about the TrueAllele DNA results. Following the indictment, the defense filed a motion to try and preclude the TrueAllele evidence, with the state submitting a response. On February 11, 2025, the judge admitted TrueAllele into evidence without a hearing. Then, on April 2 and 3, 2025, Mr. Allan testified in the first jury trial. On February 13, 2026, Mr. Allan testified in Mr. Holley’s re-trial. |
| Outcome | On April 16, 2025, after a month-long trial and six days of deliberation, the jury was unable to reach a unanimous decision, and the judge declared a mistrial. Following a re-trial, the jury found Mr. Holley not guilty on March 18, 2026. |
