Samira Calehr says that her 11-year-old son showed signs that he knew he was going to die days before he boarded Malaysia Airlines Flight 17.

According to Calehr, her son, Miguel Panduwinata, began to act strangely in the days leading up to the horrific plane crash on July 16.

Instead of being excited to fly to Bali with his older brother to visit their grandmother, Calehr says that her well-traveled son seemed bothered and asked her weird questions about death and the afterlife.

On the day before he would take off on MH17 and never return home, Calehr told the Associated Press that Miguel had a strange outburst while playing soccer, asking: "How would you choose to die? What would happen to my body if I was buried? Would I not feel anything because our souls go back to God?"

Later that night, Miguel refused to let his mother go and she slept beside him on their last night together.

The next morning, Miguel and his 19-year-old brother Shaka prepared for their long journey. Meanwhile, their other brother, Mika, 16, wasn't able to get a seat on Flight 17 and was set to fly out the following day.

However, right before they left, Miguel ran towards his mother and hugged her, saying, "Mama, I'm going to miss you. What will happen if the airplane crashes?"

In response, Calehr reassured her son that "Everything will be OK."

Eventually, she watched the two boys walk away, but Miguel kept looking back with a sad look in his eyes.

Two hours after the flight took off, Calehr learned about its fatal crash.

Now, she says, "I should have listened to him."

On Sunday, U.S. Secretary of State John Kerry opened up about the overwhelming evidence pointing to Russia's involvement in the Malaysia Airlines Flight 17 crash last week.

Passenger plane MH17 was carrying 298 people from 11 different countries when it was shot down from the sky by missiles and landed in the eastern Ukrainian region of Donetsk, an area controlled by pro-Russia separatists. Both the U.S. and Ukrainian government accuse rebels backed by the Russian government of firing the missile. However, Russia denies that it had any involvement in the crash or that it provided the rebels with sophisticated missile systems.
