Graham Dwyer's trial has heard he appears to have worked a normal eight-hour work shift on the day Elaine O'Hara was allegedly stabbed to death.
The 42-year-old from Kerrymount Close, Foxrock denies prosecution claims that he murdered the childcare worker in the Dublin Mountains for his own sexual gratification.
On day 13 of the trial, the jury has been hearing from Siobhan McKevitt, an accountant and manager at A&D Wejchert – the architect's firm in Dublin where Graham Dwyer worked.
She spent a couple of hours giving evidence for the prosecution about the 42 year old's attendance both in and out of the office on dates in 2011 and 2012.
Under cross examination, she checked attendance records from the firm, and gave evidence that Graham Dwyer appears to have worked a normal eight-hour shift on August 22 – the day Elaine O'Hara was allegedly murdered.
The childcare worker was last seen at Shanganagh cemetery in the evening time.
Her remains were found at Killakee Mountain in September 2013.
