Questions Remain in Case of Teen Who Died After Pretending to Be Oligarch's Son

Zac Brettler, a 19-year-old from a wealthy family, died by jumping off a balcony in London after pretending to be a Russian oligarch's son to impress friends.

Brettler befriended crypto millionaire Akbar Shamji and gangster Dave Sharma under his fake identity. Questions remain about their involvement.

Shamji and Sharma were set to confront Brettler about his lies on the night he died. New GPS evidence contradicts their accounts of what happened.

Sharma was found dead a year later. The reason is disputed - some say drug overdose or suicide.

Police overlooked key GPS evidence from the car Shamji drove the night Brettler died. They deny serious errors but admit the case won't be reopened.
