Jealous love-rival murders former girlfriend's new fiancé and then shoots himself in the head in front of his horrified ex outside hotel in Polish tourist town

Outside a hotel in Poland, a jealous ex-boyfriend shot himself in the head in front of his horrified ex after shooting dead his ex-girlfriend's new fiancé.

Kordian Domagaa, who had recently become engaged to Bachosz's ex-girlfriend Julia Harmaciska, was killed by him last night.

In distressing photographs, Domagaa is seen lying on the ground with his upset 20-year-old fiancée crouching over him in the picturesque tourist district of Poznan, Poland, outside a city center hotel.

When Bachosz shot her fiancé again while he was on the ground, she became visibly upset and screamed for help. Bachosz then fatally shot himself.

A video shows horrified staff and diners at the restaurant outside the city's NH Hotel calling for armed police, who then rush to the scene.

The murderer had a previous relationship with Julia Harmaciska (pictured), which he reportedly found difficult to accept.

Last night, Kordian Domagaa was killed by Mikoaj Bachosz outside a Polish hotel.

According to one eyewitness, "When the shooting started, people just fled in terror." The moment he shot the man, panic started to spread.

He later shot himself in the head, as reported.

The two men, ages 30 and 31, died in the incident that happened on Sunday night, according to police spokesman Andrzej Borowiak.

Domagaa, a blogger and artist who served as a local councilor as well, was reportedly with Harmaciska during a romantic weekend when the murderer struck.

Kamil Grzebyta, Domagaa's shocked friend, wrote on social media in a post that he was at a loss for words: "I don't know where to begin because today's news has shocked me so much that it's hard for me to find the words."

"While some news reports can elicit strong feelings in a person, true sadness can only be felt when a tragedy directly affects your friends and loved ones.

"A young boy was shot dead in front of his fiancée yesterday in broad daylight.

He was likely the most upbeat and joyous person I've ever met. He was a blogger and an artist who was always friendly and smiling.

The fact that his murderer was also a friend of mine, he continued, was equally shocking.

Kamil Grzebyta, Domagaa's (pictured) shocked friend, expressed his confusion in a social media post by writing: "I don't know where to begin because today's news has shocked me so much that it's hard to find the words."

According to reports, Domagaa and Harmaciska were having a romantic weekend when the killer struck. Domagaa is a blogger and artist who also served as a local councilor.

He is a young, intelligent man with opportunities, and I would never have predicted that he would pick up a gun and start shooting.

"It is unforgivable, but I can't imagine what must have gone through his mind to commit such a cruel crime."

Another victim friend remarked, "This death makes no sense. He was killed simply because he fell in love.

According to local reports, Bachosz was a legal assistant with a "bright future" who "tracked the couple down on social media."

According to reports, Bachosz had a relationship with Domagaa's fiancée that he found difficult to accept had ended.

The perpetrator had been granted permission to possess a gun for sporting purposes since 2018, according to the police. Unmet love was the driving force. Tomorrow is scheduled for a postmortem.
