A controversial facial recognition system let police quickly discover the name of the captured suspect in Thursday's shooting at a Maryland newspaper, officials said.
"We would have been much longer in identifying and being able to push forward in the investigation without that system," Tim Altomare, Anne Arundel county police chief, said at a press conference Thursday.
The suspect was carrying no identification when he was apprehended.
Initial attempts to use fingerprints didn't work, as there was a "lag" on the computer system, Altomare said.
So police ran an image of the man through the Maryland Image Repository System (MIRS), which compares photos to millions of driver's license pictures and mug shots.
Despite facial recognition's role in identifying the shooter, critics have questioned the use of the technology.
