The derelict NSW cottage paranoid mother and son created before violent police standoff

Barberic weapons, booby-traps and Molotov cocktails riddled the creepy fortress where a paranoid mother and son lived before their violent siege with police.

Fiona Barbieri and her then 19-year-old son, Mitchell, have been jailed for killing a detective in 2012 after barricading themselves in the villainous house.

NSW Detective Inspector Bryson Anderson was stabbed to death by Mitchell shortly after arriving at the derelict western Sydney cottage after receiving reports the teenager was firing arrows at an electrician on December 2.

Swords, barbed wire garrotes, a homemade spear with four barbs, electronic cattle prod, slingshots, hunting knives and a 4.5 kilogram sledgehammer were among the savage weapons found hidden in the nooks and crannies at the house following Anderson’s death, the Daily Telegraph reported.

The duo had collected a pile of weapons in the centre of the cottage so they could make ‘their last stand’ against the heavy police presence surrounding the Oakville house.

WEAPONS INSIDE THE BARBIERI FORTRESS 

  • Swords, homemade spears and slingshots, hunting arrows
  • Hunting knives and electronic prods
  • 4.5kg sledgehammer  
  • Barbed wire garrotes 
  • Gas bottles attached to flame thrower
  • Two neapolitan mastiffs weighing 70kg each and were bred to kill people
  • People traps covered in leaves and wooden boards with 10 cm nails 
  • Molotov cocktails 

The mother-son duo surrounded their five acre property with booby-traps, including wooden boards with 10centimetre nails.

The boards were buried in leaves and designed to severely injure anyone who stepped on it.

Gas bottles attached to flame-throwers were found at ‘strategic’ points in the run-down brick cottage the deranged pair declared self-governed.

Two traditional fighting dogs bred to kill humans weighing 70 kilograms each, known as neapolitan mastiffs, were also kept at the property and lived in one of the bedrooms.

The duo, who had an ‘unhealthy’ relationship, began constructing the monstrous fortress in 2008, four years before the detective was killed.

They lit candles at night after their electricity was cut off.

The then 45-year-old Fiona, who suffers from paranoid schizophrenia, was made redundant from her American Express role and became crippled with debt as she smoked drugs daily while her mental health plummeted, the publication reported.

Long time tension between the Barbieri’s and their neighbour spiraled out of control when they spotted Kevin Waters installing flood lights on his property, the Supreme Court previously heard.

Fiona – swinging a baseball bat – and Mitchell – armed with a crossbow – confronted the electricians working for Mr Waters and fired two arrows but narrowly missed.

Det Insp Anderson arrived at the scene and ordered the door to be kicked.

He was stabbed twice by Mitchell – once in the cheek and fatally to the chest.

As he lay dying, the court heard that Fiona was heard screaming, ‘it’s his own f****** fault.. he f***ing deserved it… let the dog c*** die… he deserves to f****** die’.  

Mitchell pleaded guilty to murder and received a 35-year sentence, which was slashed to 21 with a minimum of 15 years on appeal.

Fiona pleaded guilty to manslaughter and was sentenced to 10 years with a non-parole period of six.

Mitchell pleaded guilty to murdering the detective (pictured centre with his wife and three children) as his mother pleaded guilty to manslaughter. Both were jailed
