The father of a Bulgarian 23-year-old who went missing on May 12, begs US President Barack Obama for help.

Vladimir Dimitrov, father of Petar Dimitrov, wrote a letter to the US president to ask for assistance for finding his son.

Petar went to the US Embassy in Sofia for his visa interview. He was planning to go on a Work and Travel program in USA, but his request for visa was rejected. The young man was supposed to meet friends in front of the Embassy, but he did not show up. His phone has been switched off since then.

The security cameras show Petar entering the Embassy, but there is no record of him going out of it.

“US Embassy officials said the boy has left the building, but there is not a single proof for that,” said Nikolay Kolev-Bosiya who is helping the father solve the mystery.

After pointlessly watching the security tapes, Vladimir Dimitrov wrote a letter to Barack Obama through the White House website, with the help of the Bulgarian Embassy in Washington.

“I do not blame anyone, but in order to require help from the Bulgarian institutions, I need to have proof that my son has left the building,” the father wrote, asking the US president for information on his son's psychological condition.

Dimitrov finds the possibility of his son's illegal immigration to USA impossible because he did not have enough money.

“Petar was not a conflict person and would not do anything irrational because of a visa rejection,” he added.

Petar Dimitrov is more than 180 cm tall, with strong physics. He is a sophomore in the Police Academy in Sofia, majoring in “National Fire Safety and Protection of Population”.
