A THIRD person was yesterday arrested and charged with the murder of Scarsdale teenager Timothy O’Brien.
Detectives took Lisa Trezise, 29, of Ballarat, into custody yesterday morning as she arrived at the Ballarat Law Courts where she was due to face a string of other charges connected to the murder.
She is part of a trio accused of bludgeoning the autistic 14-year-old to death at a Scarsdale farmhouse on January 5 this year.
Joel Henderson, 40, of Wendouree, and Darren Wilson, 33, of Ballarat, were arrested and charged with murder hours after the alleged attack, in which Timothy was killed by up to 20 blows to the head.
It is alleged Trezise was at the farmhouse when Timothy was murdered and helped the accused killers flee before attempting to destroy evidence.
She is also accused of assaulting Timothy’s stepfather Peter Williams.
Mr Williams was allegedly lured to the property by a teenage girl who had been romantically involved with Wilson and had complained to him that she had seen Mr Williams peering at her through the farmhouse window on an earlier occasion.
Wilson and Henderson had allegedly discussed how they would bash Mr Williams when he arrived at the farmhouse.
Mr Williams was allegedly attacked and struck several times before Timothy, who was armed with a baseball bat, went to help his stepfather and was murdered.
Trezise now faces one charge of statutory murder, as well as being an accessory after the fact, intentionally causing serious injury, recklessly causing serious injury, intentionally causing injury and criminal damage.
All three matters were adjourned until Thursday when a five day committal hearing will begin.
