Belfast , Northern Ireland ( CNN ) -- Final preparations are being made for the funeral Monday of slain Irish newlywed Michaela Harte-McAreavey . The 27-year-old was found strangled in her hotel room on the Indian Ocean island of Mauritius last Monday . She was killed less than two weeks after her wedding . Her funeral will take place Monday afternoon at the church where she married Gaelic footballer John McAreavey on December 30 . The president of the Republic of Ireland , Mary McAleese , will head dignitaries among thousands expected to attend a requiem mass at St. Malachy 's Church , Ballymacilroy , Northern Ireland . The Catholic primate of all Ireland , Cardinal Sean Brady , will be among senior clerics at a service led by McAreavey 's uncle Bishop John McAreavey , who married the couple two and a half weeks ago . Hundreds of people attended Harte-McAreavey 's wake at the Harte family home in County Tyrone over the weekend . Three suspects in her death are all employees of the luxury hotel where the newlywed was found strangled , according to the Mauritius Police Force . Room attendant Avinash Treebhoowoon , 29 , and Sandip Moneea , 41 , a floor supervisor , have been charged with murder . Room attendant Raj Theekoy , 33 , faces a conspiracy charge . Police said one of the men has confessed and participated in the reconstruction . Authorities believe the men were inside the teacher 's hotel room when she returned alone . `` We presume they were inside and burgling the room when the lady returned and were surprised and attacked her , '' Mauritius police Superintendent Yoosoof Soopun , who is leading the investigation , said last week . Authorities said the killer used an electronic key card to enter the room . The former beauty queen 's husband was in the restaurant of the hotel when his wife was killed , and is not a suspect , Soopun said . An autopsy showed that she died of asphyxiation . Harte-McAreavey taught Irish at St. Patrick 's Academy in Dungannon , County Tyrone , in Northern Ireland . She won the Ulster Rose of Tralee contest and participated in other beauty pageants .
