This market will resolve according to the next listed date (ET) on which any individual is arrested in direct connection with the December 13th Brown University mass shooting.

Only arrests of individuals for alleged participation in the planning or execution of the shooting itself will qualify. Arrests made solely for related or subsequent conduct will not qualify.

A qualifying arrest/detention includes:
* Being taken into physical custody by law enforcement authorities (including federal, state, local, military, or international law enforcement)
* Voluntarily surrendering to law enforcement authorities in response to an arrest warrant
* Being formally booked or processed following detention
* Being handcuffed by a state authority and taken to a police station
* Surrendering at a police station or courthouse with their attorney
* Being placed under house arrest or electronic monitoring

The following scenarios will NOT qualify as an arrest/detention
* An arrest warrant is being issued but not executed
* Being questioned or interviewed without arrest
* Being named in an indictment without arrest

If no qualifying arrest occurs by December 31, 2025, 11:59 PM ET, this market will resolve to “No Arrest in 2025”.

The primary resolution source for this market will be official information from the arresting government and law enforcement; however, a consensus of credible reporting may also be used.
