PROBLEM: Paragraph- Sent 1: (CNN) -- German art collector Cornelius Gurlitt, whose nearly priceless collection was confiscated because it was suspected to contain pieces looted by the Nazis, died Tuesday and left the masterpieces to a Swiss museum.
Sent 2: One day after Gurlitt's death at the age of 81, the Museum of Fine Arts Bern announced that Gurlitt had named it "his unrestricted and unfettered sole heir."Sent 3: The news came as a surprise, the museum said Wednesday, because Gurlitt had never had any connection to it.

Sent 5: Gurlitt had undergone major heart surgery and was hospitalized for many weeks, his representative said in a statement.

Sent 7: The collection was confiscated as part of an investigation into tax fraud, but then it was thought that some of the paintings may have been works that were looted by the Nazis.

Sent 9: Under the agreement, works owned by Gurlitt that were not under suspicion were returned to him.
Sent 10: Those suspected of being stolen were to be held securely while a task force investigates their provenance -- and will be returned to their original Jewish owners or their descendants if a claim is proven.
Sent 11: Gurlitt's representative said that with the art collector's death, the investigation into the collection ceases.
Sent 12: The court that was handling the investigation proceedings will now function as an estate court in the case.
