"Imagine spending 18 years wanting a son and finally having Mohammed," said the retired naval officer.
Like others who lost loved ones during the uprising, Ahmed said he voted for President Mohammed Morsi, who had been imprisoned under Mubarak for his activities with the then-outlawed Muslim Brotherhood group. Ahmed said he met with Morsi after he was elected last summer in the nation's first free presidential vote.
"I told him there must be justice for my son. He took the picture of Mohammed and another boy from Suez and kissed it. He asked to keep the pictures and was clearly affected."
In another case involving protesters, an Egyptian criminal court on Saturday invoked a presidential amnesty and dismissed charges against 379 people accused of taking part in deadly clashes with police.
The charges stem from nearly two weeks of street fighting on downtown Cairo's Mohammed Mahmoud street in November 2011 that left 42 people dead.
Young protesters, mostly die-hard soccer fans known as Ultras, led demonstrations against police near the Interior Ministry and Tahrir Square, the hub of Cairo's activist movement. They were demanding a timetable for the military officers who were then ruling the country to hand over power and hold presidential elections.
Since the revolt, security lapses and a weakening of police powers has left many feeling more vulnerable, particularly the country's Coptic Christian minority.
On Saturday, police said they arrested seven suspected of attacking stores owned by Christians in the southern village of Marashda, in Qena province. Several shops were torched early Friday when word spread that a Christian villager had sexually assaulted a 6-year-old girl. State prosecutors ordered the young girl to be given a physical examination as part of the investigation.
