The jury in the Graham Dwyer murder trial is hearing further details of text messages sent between Elaine O'Hara's mobile and a phone allegedly used by the accused.
In one exchange of messages from April 2011 the man asks her to find him a victim to stab.
He also talks of walking in the woods at dusk with a hunting bag to prepare for the murder.
He texts that ''it's your fault I want to kill and you won't let me stab you''.
