The Maryland Supreme Court ruled Tuesday that firearms experts will no longer be able to testify that a bullet was fired from a particular gun. The decision is likely the first by a state supreme court to undercut the widespread forensic discipline of firearms identification, which is used in criminal cases across the country.
In a 4–3 decision first reported by The Baltimore Sun, the Maryland Supreme Court overturned the murder conviction of Kobina Ebo Abruquah after finding that a firearm expert's trial testimony linking Abruquah's gun to bullets found at a crime scene wasn't backed up by reliable science. In the majority opinion, Maryland Supreme Court Chief Justice Matthew J. Fader wrote that "firearms identification has not been shown to reach reliable results linking a particular unknown bullet to a particular known firearm."
