An Egyptian forensic expert cast doubts Monday on laboratory reports received from the Gulf emirate of Dubai over the murder of Lebanese singer Suzanne Tamim, allegedly killed by order of a real estate tycoon. "There are 20 reasons to question the forensic reports related to the autopsy conducted on the body of (singer) Suzanne Tamim," forensic doctor Ahmed Ibrahim told the Cairo criminal court, which will resume hearing the headline-hitting case Tuesday. Tamim was killed in her hotel room in 2008, and Egyptian businessman Hesham Talaat Moustafa was accused of paying ex-policeman Mohssen el-Sukkari two million dollars to slay her. Dr. Ibrahim was cross-examined in Cairo Criminal Court by lawyers for el-Sukkari and Moustafa as he mentioned some remarks on the way by which the time of the murder was defined. After three hours of hearings Monday, the court adjourned the trial until Tuesday, when witnesses are to be called by Moustafa's chief defence lawyer Farid el-Deeb to counter the evidence of Dirzadeh Wajih el Din, 38, a Pakistani engineer who installed the surveillance cameras in the Dubai hotel where Tamim lived.
