Answer the following question: Information:  - The Tyrrhenian Sea (, , , ) is part of the Mediterranean Sea off the western coast of Italy. It is named for the Tyrrhenian people, identified since the 6th century BCE with the Etruscans of Italy.  - Salvatore La Barbera ( Palermo , April 20 , 1922 -- January 17 , 1963 ) was a Sicilian mafioso . Together with his brother Angelo La Barbera he ruled the Mafia family of Palermo Centro . Salvatore La Barbera sat on the first Sicilian Mafia Commission that was set up in 1958 as the capo mandamento for Mafia families of Borgo Vecchio , Porta Nuova and Palermo Centro . La Barbera disappeared during the First Mafia War , a victim of the lupara bianca , never to be seen again . The Palermo police suspected that Salvatore Greco `` Ciaschiteddu '' and his cousin Salvatore Greco `` The Engineer '' had arranged a deal whereby Tommaso Buscetta betrayed his former friend , killed him and disposed of his body in the furnaces of his glass factory . Buscetta claims to know nothing about the disappearance .  - Palermo (Sicilian: "Palermu", , from , "Panormos", , "Balarm"; Phoenician: , "Ziz") is a city of Southern Italy, the capital of both the autonomous region of Sicily and the Metropolitan City of Palermo. The city is noted for its history, culture, architecture and gastronomy, playing an important role throughout much of its existence; it is over 2,700 years old. Palermo is located in the northwest of the island of Sicily, right by the Gulf of Palermo in the Tyrrhenian Sea.  - The Sicilian Mafia, also known as simply the Mafia or Cosa Nostra ("Our thing"), is a criminal syndicate in Sicily, Italy. It is a loose association of criminal groups that share a common organisational structure and code of conduct. The basic group is known as a "family", "clan", or ""cosca"" or "cosche" in Sicilian. Each family claims sovereignty over a territory, usually a town or village or a neighbourhood ("borgata") of a larger city, in which it operates its rackets. Its members call themselves "men of honour", although the public often refers to them as "mafiosi". The mafia's core activities are protection racketeering, the arbitration of disputes between criminals, and the organizing and oversight of illegal agreements and transactions.  - Sicily is the largest island in the Mediterranean Sea. It constitutes an autonomous Region of Italy, along with surrounding minor islands, officially referred to as "Regione Siciliana" (in Italian, Sicilian Region).  - The Sicilian Mafia Commission, known as Commissione or Cupola, is a body of leading Sicilian Mafia members to decide on important questions concerning the actions of, and settling disputes within the Sicilian Mafia or Cosa Nostra. It is composed of representatives of a mandamento (a district of three geographically contiguous Mafia families) that are called "capo mandamento" or "rappresentante". The Commission is not a central government of the Mafia, but a representative mechanism for consultation of independent Mafia families who decide by consensus. "Contrary to the wide-spread image presented by the media, these superordinate bodies of coordination cannot be compared with the executive boards of major legal firms. Their power is intentionally limited [and] it would be entirely wrong to see in the Cosa Nostra a centrally managed, internationally active Mafia holding company," according to criminologist Letizia Paoli. The jurisdiction extends over a province; each province of Sicily has some kind of a Commission, except Messina, Siracusa and Ragusa. Initially the idea was that the family bosses would not sit on the Commission, but in order to prevent imbalances of power some other prominent member would be appointed instead. However, that rule was not obeyed from the start. According to the pentito Tommaso Buscetta the Commission first came into being "to settle disputes between members of the various families and their bosses" in order to discipline members of each family. Only later did its function expand to "the regulation of the activities of all families in a province."  - Italian term pentito ("he who has repented"; plural: "pentiti") is used colloquially to designate people in Italy who were formerly part of criminal or terrorist organizations, and who, following their arrests, decided to "repent" and collaborate with the judiciary to help further investigations. The judicial category of "pentiti" was originally created in legislation passed by the Italian government in the 1970s to combat violence and terrorism during the so-called Years of Lead. The correct technical name used for them is "collaborators of justice". In the wake of the Maxi Trial in Palermo in 198687, and after the testimony of Tommaso Buscetta, the term came into widespread use in Italy for all former members of the Sicilian Mafia who had abandoned their organization and started helping investigators.  - Historically a mandamento was the part of Italian territory under the jurisdiction of a "pretore" which is a kind of magistrate. These divisions were abolished in 1923.  - Angelo La Barbera (July 3, 1924  October 28, 1975) was a powerful member of the Sicilian Mafia. Together with his brother Salvatore La Barbera (Palermo, April 20, 1922  January 17, 1963) he ruled the Mafia family of Palermo Centro. Salvatore La Barbera sat on the first Sicilian Mafia Commission that was set up in 1958 as the capo mandamento for Mafia families of Borgo Vecchio, Porta Nuova and Palermo Centro.  - Southern Italy or Mezzogiorno (literally "midday") is the traditional term for the southern regions of Italy, encompassing the southern section of the continental Italian Peninsula, the island of Sicily, and usually the island of Sardinia. It generally coincides with the administrative regions of Abruzzo, Apulia, Basilicata, Campania, Calabria, Molise, Sicily, and Sardinia. Some also include the most southern and eastern parts of Lazio (Sora, Cassino, Gaeta, Cittaducale and Amatrice districts) within the "Mezzogiorno", because these territories were also part of the Kingdom of the Two Sicilies. The island of Sardinia, although for cultural and historical reasons having less in common with the aforementioned regions, is frequently included as Southern Italy or "Mezzogiorno", often for statistical and economical purposes.    Given the information, choose the subject and object entities that have the relation of 'place of death'.
