The Irish teenager, who stabbed a Bulgarian restaurant owner at the seaside resort of Sunny Beach, claims he was just trying to protect his sister.
Oisin Gough, 15, wouldn't speak to journalists but sent a friend of his to present his version of the story, 24 Hours daily reported.
The messenger, who had presented himself as Sean from Dublin, said that assaulted Mariyan Martinov started it all, by trying to make passes at Oisin's sister Rebecca.
A group of Irish tourists was passing by Martinov's restaurant when he attempted to hug 19-year-old Rebecca, Sean said. She then hit him over the head with her purse and her brother jumped in to protect her.
Young Gough was peeking from his room's window throughout the whole interview, the newspaper writes. He is staying at a luxurious apartment in the Bravo hotel complex in the city. Despite previous reports that Oisin and Rebecca Gough had arrived without their parents, the newspaper claims that their mother accompanies them.
She refused to comment the case until she talks to her lawyer. Reporters were not allowed in their apartment, and Rebecca, visibly frustrated slammed the door at their faces. The family was supposed to stay in Bulgaria until Sunday, but they would have to extend their holiday because of the accident.
Martinov's mother has negated the Irish boy's story. These are all insinuations, she said. "My son couldn't make passes at another girl with his wife right there in the restaurant," the woman said indignantly. "They have a baby that's eleven months old."
Gough stabbed Martinov in the stomach with a broken bottle on June 27. He then confessed to the crime and said he was sorry and that he was drunk.
Prosecutors have already pressed charges against the teenager, reports claim. He is charged with battery, but the indictment might be changed to grievous bodily harm, depending on the medical evaluation of the victim's condition.
