Murder accused Alan Wilson stood and danced on the body of teenager Marioara Rostas (18) after pushing her remains into a shallow grave in the Wicklow mountains, a trial has heard.

Key prosecution witness and convicted criminal Fergus O'Hanlon has told the Central Criminal Court that he helped the accused man dispose of her body after wrapping it in sheets and plastic.

The jury's heard he was the partner of Alan Wilson's sister Maxine and lived at a house in Brabazon Street in The Coombe where Marioara Rostas was allegedly murdered in January 2008.

Fergus O'Hanlon denies ever being in the house while the teenager was alive. He claims on January 8th he went to the post office to get his disability allowance but received phone calls to return home.

The court heard when he got back to Brabazon Street after 5pm, Alan Wilson came down the stairs with a rifle, told him he wanted to show him something and then brought him to an upstairs bedroom where the body of a girl lay in the centre of the room.

'She looked wide awake'

He said she was wearing jeans and runners. There was a hole in her head and blood on her face, but she looked wide awake as if she were staring at the ceiling.

The jury heard Alan Wilson told him that she had been a witness to her brother being killed.

Wilson (38) from New Street Gardens in Dublin denies murdering the Romanian at 2 Brabazon Street in the Coombe on January 7th or 8th 2008.

Marioara Rostas was shot four times in the head. She was last seen by her family getting into a car with a man on Pearse Street on the afternoon of Sunday January 6th while out begging with her brother.

Fergus O'Hanlon is now being questioned by the defence about his credibility as a witness.

He has been cross examined about violence towards women and an incident at St. James Hospital Emergency department in 2009 where witnesses claim he racially abused security staff and threatened to shoot them.

The men were shot within 24 hours but Fergus O'Hanlon says that had nothing to do with him. He denies ever discharging a firearm.
