State of Michigan v Beverly McCallum

TrueAllele connects victim to basement in cold case homicide

Crime In 2002, a man’s burned remains were found in a metal locker near a Michigan blueberry field. Ten years later, police identified the remains as belonging to Roberto Caraballo. Police had other evidence suggesting that his homicide occurred in the basement of his residence. Detectives identified the victim’s wife, Beverly McCallum, and two others as suspects.
Evidence Michigan State Police Crime Laboratory scientists located possible blood under new concrete in the basement.
DNA The lab swabbed the concrete for DNA testing and generated DNA data from this evidence.
Match The crime laboratory could draw no conclusions from the concrete swab evidence due to the complexity of the mixture profile.
TrueAllele On the same data, the TrueAllele computer found that the victim’s DNA was statistically present in the possible bloodstain on the concrete with a match statistics of 23.9 trillion.
Cybergenetics    On March 27, 2024, Cybergenetics casework supervisor Bill Allan testified before an Eaton County jury at the trial of defendant Beverly McCallum about the TrueAllele DNA results.
Outcome After deliberating for two hours, the jury found the defendant guilty of second-degree murder and disinterment and mutilation of a body.
