Knives allegedly belonging to Renae Lawrence and another Kerobokan prisoner revealed Australian Bali nine member Renae Lawrence. THIS massive Commando-style knife was going to be used to kill two jail guards, in an alleged plot by Bali Nine drug smuggler Renae Lawrence and another prisoner. Authorities in Bali on Tuesday revealed the knife, along with another smaller folding knife, which they allege Lawrence and a fellow woman prisoner were planning to use in their plot. The big Commando style blade was found in the cell of Lawrence's co-plotter, Joaninha Maria Sonia Gonzales, known as Black Sonia or Black Monster. The smaller folding knife was found in Lawrence's cell.

This is the knife that we found from Sonia's room. I have no idea how this big knife could be here, past our tight security. But yes, she could," Mr Wiratna said. The other knife belongs to Renae Lawrence. We found it in Renae's room on Friday," he said. Also uncovered in weekend raids on the jail's women's block were more than 50 contraband mobile phones. And Mr Wiratna revealed that when Gonzales first came to the jail several months ago, charged with kidnapping a little French boy, she attempted to smuggle in an arsenal of Smaurai swords. The five Samurai swords and an arrow were confiscated at the time and he allowed the media to photograph them today as well. Details of the plan to kill guards were uncovered on the weekend during a raid of the women's block. Mr Wiratna had ordered the searches of female prisoners cells after photographs had surfaced in a local paper of female prisoners taking drugs. During that raid Gonzales' phone was seized and searched and the incriminating BBM chat was discovered, where Lawrence is alleged to have told Gonzales to "use the knife, use the metal chains" to kill the guards. At the time Lawrence was undergoing an appendix operation in Sanglah Hospital. It is understood that Lawrence has denied the allegations and her father, Bob Lawrence, says she has been set up.

Gonzales too has been moved to another jail. Authorities say that the two women won't be charged with conspiracy to murder but will face jail sanctions and Lawrence will be stripped of her remissions this year. Mr Wiratna said he had spoken with the Australian Consulate in Bali about Lawrence's case and explained why she had been dramatically moved out of the jail to a new jail. He said the Consulate staff indicated they wanted to meet him. And he expressed hope that Lawrence, a once trusted leader of the women's block and whom he treated as his own daughter, would redeem herself. What Renae has done is extremely disappointing. Before the case, I always thought she was a good woman. I told her that, 'you are like my daughter," Mr Wiratna said. I hope wherever she stays, Renae can be better and better. The most important thing is we have taken the best solution for all of us, as well as for Renae. I hope she will change after staying in Negara jail," he said. Mr Wiratna said the mobile phone chat between Lawrence and Gonzales was clear and he had kept the phone and evidence. I really cared about Renae before. I am disappointed. Other Australian inmates have shown good behaviour, including (Schapelle) Corby and Andrew Chan. Andrew Chan was sentenced to death but he still shows good behaviour. He never conducts any trouble. I hope this will be a lesson for Renae, as well as for other inmates. Mr Wiratna admitted that despite tight security, inmates had been able to smuggle contraband goods into the jail. We monitor the jail gate tightly. But yes, I admit they apparently could smuggle the knife and other things. They always do it with different modus that make us have to work hard to prevent it,' he said. Mr Wiratna retired from his job and yesterday an inauguration ceremony for the new Kerobokan Jail governor was held. The new Governor, Farid Junaedi, vowed to work hard to eradicate drugs and crime inside the jail.
