SearchSystems opened and checked the jail page of the Allegheny County Sheriff's Office at sheriffalleghenycounty.com (page title: Home, Allegheny County Sheriff's Office), phone 412-350-4714, Monday through Friday, 8:00AM to 3:00PM, which answered when SearchSystems opened it on September 28, 2026.
That page is the office's jail information page rather than a roster, so a search for a particular person goes through the office at 412-350-4714.

The Northern Regional Police Department, the McDonald Borough Police Department and the Trafford Police Department are each listed by the FBI across several counties including Allegheny County, so their arrests are not broken out for Allegheny County here.
