‘Class clown’ tradie, 22, stabbed at high-rise party before accused killer scales balconies to flee

A man has been charged with the murder of a young plumber described as the ‘class clown’ who was allegedly stabbed to death in Melbourne on Saturday night.

Liam Cahill, 22, was celebrating a friend’s birthday at a party on the 15th floor of the M Docklands high-rise on La Trobe Street when a fight erupted at about 10.30pm between Mr Cahill and his alleged killer.

The noise of the altercation could be heard throughout the building, with one resident telling of their fear when they heard a young woman screaming.

‘It was so loud we thought it was on our floor, but I think it was downstairs,’ the resident told the Herald Sun.

‘It was terrifying.’

The fight was heard by another resident, Rocky Petrelli, who lives in a 14th floor apartment below.

‘It was just really noisy, it was like there was elephants stomping the ground in the apartment above, that’s what I could hear below,’ Mr Petrelli told Seven News.  

The apprentice plumber from Pascoe Vale in Melbourne’s north was allegedly stabbed several times before his accused killer fled, climbing down two balconies on the side of the building in a desperate bid to escape. 

One of the apartments he’s accused of trying to break into during his alleged escape bid was Mr Petrelli’s.

‘It’s pretty scary that you think that it’s a safe building especially when you’re on the 14th floor and you’ve got someone jumping balconies to try and escape the building,’ Mr Petrelli said. 

He was unsuccessful, and climbed down another balcony to the 13th floor where he ran through an unlocked apartment in his bid for freedom.

A suspect was tackled and arrested by police a short distance from the scene. The suspect can be seen in CCTV footage lying on the ground in a corridor behind a stack of toilet rolls

Mr Cahill was given first aid by another resident of the building, but couldn’t be saved. 

The alleged murder traumatised the other party guests who had to be comforted by police at the scene.

‘Why did you do this to me?’ screamed a woman at the scene. 

A young woman with bright red hair was seen screaming in the lobby, falling to her knees in distress before being comforted by police and led away.
