Heliopolis Prosecution has received the final autopsy report regarding the victims that were killed during clashes at the Republican Guards club last July.
According to the report, the victims were shot in the head and stomach by live ammunition and suffered from internal bleeding that led to their death.
The report also added that some of the victims died within minutes of being shot in the head and heart, whilst others passed away after being transferred to hospital.
On 8 July 2013, clashes erupted between Egypt's armed forces and supporters of the Muslim Brotherhood, resulting in the death of 53 citizens and the injury of 100 more.
The Heliopolis Prosecution office asked forensics at the criminal lab to hurry in issuing the report concerning weapons and bullet casings used, as evidence in ongoing investigations.
Egypt's armed forces have accused the Muslim brotherhood of trying to storm the Republican Guards headquarters.
Several prominent Muslim brotherhood figures, including Mohamed El-Beltagy, and Islamist preacher Safwat Hegazy, are being accused of inciting the attack against security forces - police and army - at the Republican Guards club.
Meanwhile, Eastern Cairo Prosecution continues to question 700 Muslim Brotherhood members and supporters, tens of whom have been accused of incitement to violence and murder, both outside the Presidential Guards club and during another violent clash with security forces at the Unknown Soldier memorial.
