Gardai got phone records up to day Elaine went missing
DATA: Information from hundreds of mobile sites also obtained
GARDAI investigating the death of Elaine O'Hara obtained call records for her number up to the day she disappeared, and for murder accused Graham Dwyer's number up to three months after, the Central Criminal Court heard.
The jury was told the details provided to detectives were among records for five different phone numbers that they investigated, along with information from hundreds of mobile cell sites around the country.
Mr Dwyer (42), an architect of Kerrymount Close, Foxrock, is pleading not guilty to the murder of Ms O'Hara (36) at Killakee, Rathfarnham on August 22, 2012.
Ms O'Hara, a childcare assistant from Killiney, was last seen alive near Shanganagh Cemetery in Shankill that day.
Her remains were found by a dog walker in undergrowth in the Dublin mountains on September 13, 2013.
The prosecution maintains Mr Dwyer killed her for his own sexual gratification.
Telecom engineer Conor O'Callaghan told Sean Guerin SC, prosecuting, that among the data he provided was for a mobile phone number 086 3311207.
The customer name was recorded as Elaine O'Hara with an address at Ardmeen Lodge, Newtownpark Avenue, Blackrock, a date of birth of March 17, 1976. The number activation date was December 12, 2000.
Call records were provided for the dates October 28, 2011 to August 22, 2012.
Records were also provided for 086 1759076, an unregistered prepaid number that was activated on September 15, 2011 and purchased at 02 Retail, Grafton Street on November 30.
Mr O'Callaghan said information from 458 unique mobile phone cells by O2 alone had been compiled.
Jamie Clifford, information disclosure specialist with Hutchison 3G UK - trading as Three - was questioned about the purchase of a phone with the number 083 1103474.
The name of the subscriber was listed as Goroon Caisholn and it was purchased at a shop on Grafton Street on March 25, 2011.
The date of birth on the account was April 4, 1992 and the address given was Oak Lawn, Clerihan, Co Tipperary, with an 086 phone number as a contact number. Records were provided for calls between October 7, 2011 and October 17, 2013.
Mr Clifford told Mr Guerin he provided cell site information in relation to 27 cell sites, and rectified and produced data for 160 cell sites there had been a problem with.
He provided data for another phone, with a number 087 2100407.
The subscriber for a period in 2011 and 2012 was A&D Wejchert Architects at Lower Baggott Street and the name given was Siobhan McKevitt.
The number was connected on April 7, 2011 and disconnected on October 16, 2012.
Mr Clifford told Mr Guerin this was a contract that had been set up for that period.
He provided call data details for the number for dates between October 7, 2011 and November 30, 2012. The jury heard previously this number was used by Mr Dwyer.
The jury was told Mr Dwyer accepted he had been the registered owner of five cars.
Superintendent JJ Keane then gave evidence of road toll records between Galway and Dublin on July 4, 2012. He was attempting to identify a car using the toll booths at the M6 outside Galway and the M4 in Dublin.
Tracey Burke of Easytrip gave evidence that an eflow tag registered to Mr Dwyer was used for a blue Audi TT, which passed through the M4 East Kinnegad toll on July 4, 2012 at 6.04am.
It passed the N6 toll at Ballinasloe at 7am, and at 12.45pm and passed the M4 West Kinnegad toll at 1.47pm.
The case continues.
