A jury has heard gardaí found a message on Elaine O’Hara’s mobile by someone telling her “they must get fit for the murder”.

The 42-year-old architect Graham Dwyer, of Kerrymount Close, Foxrock, denies murdering the childcare worker at Killakee Mountain in Dublin in August 2012.

The trial has been hearing evidence of how gardaí extracted thousands of text messages from the hard drive of Elaine O'Hara's Apple Mac computer.

Forensic analysis was also carried out on her two iPhones.

Det Sgt Alan Browne said several messages were recovered from between Elaine O'Hara's phone and an 083 number.

They were discovered in unallocated clusters on the computer hard drive where deleted content can be found.

One recovered text read “Good, looking forward to getting new bike tomorrow to try and lose weight. Must get fit for the murder.”

Another read: “Terrible 15pc pay cut and came 5th in flying''. One from Elaine's mobile reads 'yes sir, dying for more play sir'. 

Earlier the court heard from DG Breege Wallace of the Computer Crime Unit that a calendar entry retrieved from Elaine O'Hara's Macbook dated June 30th 2011 notes an 083 number as being Graham's phone.

However at the very beginning of this trial in his opening address barrister, Sean Guerin said it is the prosecution's case that the childcare worker was in communication by phone with Graham Dwyer.

He said that the content of the messages found on a number of phones showed that they had an S&M relationship which involved stabbing.

Two of the witnesses for this section of the case FINANCIAL CRIMES ANALYST Numbers 1 and 2 will remain anonymous to protect their identities as they've worked for the Criminal Assets Bureau.
