The mystery surrounding Tufts University student Rumeysa Ozturk's whereabouts after she was picked up by federal immigration agents has shocked many — and is now complicating her legal proceedings. Why it matters: The case's question about jurisdiction — typically a granular area of court proceedings — could affect how ICE detains foreign-born residents and how it communicates about detentions in the future.

Rumeysa Ozturk's detention sparked continued protests, allegations that federal officials broke the law, and more.
