CAIRO , Egypt ( CNN ) -- An Egyptian business tycoon and a former police officer have been found guilty of last July 's slaying of a rising Lebanese pop singer . Suzanne Tamim was found dead in her Dubai apartment in July . The case , with its high-profile victim and defendant , has captivated Egypt and the region . A judge convicted and sentenced to death real estate mogul Hisham Talaat Moustafa and the former officer Muhsen el Sukkari on Thursday . Egypt 's Grand Mufti -- the country 's highest religious official -- will review the sentence and rule on June 25 if the men will be executed , the judge said . Because the two men were sentenced under Islamic law , it is widely expected that they would be hanged . Moustafa 's lawyer told reporters outside the courtroom that he will appeal the conviction , saying there was `` a one million percent guarantee '' the sentence would be overturned . The singer , Suzanne Tamim , was found slain in her apartment in the United Arab Emirates . She had been stabbed and her throat slit . Prosecutors alleged that Moustafa , a parliament member for the ruling National Democratic Party , paid el Sukkari $ 2 million to kill Tamim . During the trial , Moustafa 's lawyer told CNN his client loved the singer , but could not take Tamim as a second wife because his family objected . Polygamy is legal in Egypt , and it 's not unusual for men -- such as Moustafa , a married father of three -- to take on additional wives . Prosecutors have said Tamim 's death was a `` means of taking revenge , '' but have not elaborated . Moustafa and el Sukkari claim the prosecution 's evidence could have been fabricated or tampered with by UAE authorities and should not be used against them . Although Tamim was killed in the United Arab Emirates , the Egyptian judiciary tried the case in Cairo because the accused were arrested in Egypt . After his arrest in September , Egyptian authorities indicted Moustafa , stripped him of his parliamentary immunity and jailed him pending trial . He also resigned as chairman of Talaat Moustafa Group -- a conglomerate with construction and real estate arms that was founded by his father , Talaat Moustafa . Moustafa 's brother , Tarek Talaat Moustafa , now chairs the company . CNN 's Raja Razek and Housam Ahmed contributed to this story .
