A man in Florida has been arrested for fatally stabbing his boss and another man.

Tilus Lebrun, 36, was arrested Thursday for the stabbing murder of his boss, Dimitrios Karaloukas, 61. According to NBC News, Lebrun murdered Karaloukas because the man took a photograph of him and posted it online without Lebrun’s permission.

“'I killed him because he took my photograph on March 2 and posted it on the internet,” Lebrun told authorities.

Witnesses said Lebrun was working at Jimmy The Greek Taverna Restaurant Thursday night. When Karaloukas sat down, Lebrun struck and stabbed the restaurant owner three times in his left side and in his back. Lebrun then turned his rage on another employee. He stabbed the unidentified man multiple times and he required lifesaving surgery.

According to The Daily Mail, the photograph in question is marked June 2012 online, making it unclear why Lebrun told authorities it was a recent event that caused his murderous actions. The March 2 photograph has not been found.

'They need to learn how to respect people. I have three kids in Haiti. I know they will suffer, but they will survive,' Lebrun told police.

Dimitrios Karaloukas passed away from his injuries an hour after the attack.

Lebrun has been charged with murder.
