It was on July 17, 2014 when the international flight from Amsterdam to Kuala Lumpur, Malaysian Airlines Flight MH17, crashed after being shot down, killing 298 people on board. Glenn Thomas was one of the MH17 passengers.

For Thomas's nephew, getting the answers for the "What?" "When?" and "Where?" were not enough. He wanted to know who murdered his uncle, and why?

According to some Western governments, and although the Kremlin fervently denies it, there were alleged Russian rebels who fired missiles at the plane. The Dutch Safety Board (DSB), on the other hand, has been investigating the disaster and recovering the wreckage for months.

"They claimed it was not safe for them to enter what was - in effect - a war zone. Parts of the country are still in the throes of a civil war," said Withers, according to BBC.

Withers also met a mother who lost her son and her son's girlfriend in the crash.

"No one takes responsibility for what has happened. You can just shoot a plane out of the sky and nothing happens, that makes me angry. I want the killers to be punished. I want to look in their eyes and show them my pain and show them the beautiful young people they killed. I want them to know what they did. I don't know if they care," said Silene Fredriksz, according to BBC.

International officers, alongside the DSB, identified BUK missile fragments and also released a video that shows a BUK missile launcher entering the eastern part of Ukraine. Another investigative journalist named Elliot Higgins, founder of the Bellingcat, claimed to show the path of the BUK missile launcher which was eventually incorporated in the Dutch criminal investigation.

Although the criminal inquiry is due to report 18 months after the tragedy, Withers is still hopeful that justice will not be forever denied to the victims.
