On Sunday, police officer Liam Trimmer, 29, and his girlfriend celebrated their recent engagement with friends and family in attendance. The ceremony was held at his home outside Perth in Western Australia.

However, Helga's celebrations came to an abrupt end when Trimmer suddenly fell.

During his fall, he was said to have suffered a wound to his throat that struck a major artery, according to Sky News. Then he bled to death.

Several guests are said to have provided first aid to the police officer, but his life could not be saved. According to the newspaper, he died before the ambulance arrived.

New details: – Freezing to death

– Everything is done

The 29-year-old was originally from the UK, but moved to Australia in 2013 to become a police officer. Police Chief Colonel Blanche says party attendees did everything they could to save Trimmer.

Blanche describes the 29-year-old as an “exceptional officer.”

– Everything was done to save him, but it was not possible. Blanche told Channel 9 News that everyone involved is in a lot of pain right now and I hope they wake up from this nightmare.

The police chief says Trimmer was a confident and capable young man who had “his whole life ahead of him,” and that it's all sad.

He explains that the entire community is affected by the death of a police officer, regardless of the circumstances of the death.

– It's just a tragedy, he tells the channel.

It is not yet known why Trimmer fell. Police are investigating the circumstances of the incident.

The police officer is known to some from the BBC series Wanted Down Under, where he gave advice to young people who wanted to move to Australia.

He is said to have had a close relationship with his friends, family members and colleagues, who are now receiving assistance from the Police Department of Health and Social Welfare.

State Police Minister Paul Papalia extended his condolences to the relatives of the victims. The same was done by Deputy Prime Minister Rita Saffioti, who described the incident as “terrible.”
