This Austrian dad who allegedly murdered his three children before trying to poison himself to death has complained about the food in the hospital where he was taken and said that the handcuffs are too tight.

Harald Kopitz, 56, an Austrian man living in Croatia, allegedly killed his two seven-year-old twins, a boy and a girl, and his four-year-old son, before trying to kill himself in the district of Mlini in the Croatian capital Zagreb on Saturday night (25th September).

After spending two nights in police custody, the suspect is set to be presented before a judge at the Zagreb County Court.

He complained about the food and how he was being treated in hospital, and also said that the handcuffs were too tight, according to local media outlet Telegraf.

He is also reported as having said that he was unhappy that he was still alive.

The suspect had been out of work for a long time and called his friends to try and find work, but to no avail. He also said that his lease on his rented apartment had expired and he had nowhere to go.

The police arrived at the household on Saturday night and found the children dead with Kopitz still alive but in need of urgent medical attention due to suspected poisoning.

The three children were spending the weekend at their dad’s house as their parents are divorced.

After being discharged from hospital, Kopitz was taken to a psychiatric clinic for evaluation before being questioned by the police.

Kopitz told the police he had been out of work for a long time and he could no longer keep up with the rent and had nowhere to go, according to local media outlet Blic.

He is quoted as having said that he had decided to kill himself as a result of his financial predicament, but he also wanted to take his children because “he didn’t want to die alone”.

Kopitz said that he regrets that he is still alive and that he will try to kill himself again the moment he gets the opportunity.

On the night of the alleged triple murder, he reportedly posted on Facebook: “Goodbye everyone, I’m leaving you, I can’t do this anymore.”

His girlfriend, who has not been named, dumped him because his ex-wife had been cruel to her, and the suspect, who was reportedly depressed, had run out of money, Kronen Zeitung reports.

The four-year-old boy was found dead on a bed in a bedroom while the two twins were found in the living room.

The suspect was a financial adviser with a degree from Danube University Krems, according to Kronen Zeitung.

He has worked with many well-known leasing companies and operated his own business in Vienna before opening a second company in Croatia where he has been working since 2007.

He is also reportedly a Freemason and shortly before he allegedly carried out the shocking murder, he complained on Facebook about a lack of support from his “brothers”, a reference to fellow masons.

Under Croatian law, he reportedly faces a maximum sentence of 50 years in prison.

Autopsies have been carried out on the children, but additional toxicological examinations are being done to determine how they were killed.

The investigation is ongoing.
