I wondered that too. It doesn't say, but does state: "Data from the license plate readers, known in law enforcement as LPRs, was searched 62,000 times in 2025, leading to about 1,660 cleared catalytic converter theft cases, a report from the authority said."
Also, how many missing people are there? finding 10k seems quite a lot. “one of the most effective ways Flock has been able to help find, just last year, over 10,000 missing persons”.
Based on the cited document, "leading to" seems entirely made up.
The term "missing person" calls to mind someone who is in serious danger, but a majority are something minor, like someone quitting a job without notice or taking an unannounced trip. The vast majority are resolved by finding the person alive.
Flock helping close 10K cases doesn't surprise me at all, but it doesn't meant those people wouldn't have been found without it. It may mean less work for the police, but the police don't usually put a lot of effort into a missing person without evidence they're in danger.
