Gardaí investigating the death of Elaine O'Hara have taken over 120 statements and more than 130 questionnaires.
They said their investigation into the disappearance and death of the 36-year-old is focusing on 22-24 August last year, which is the period during which she went missing.
Ms O’Hara was last seen leaving her home at Belarmine Plaza in Stepaside at around 5.05pm on 22 August.
Detectives are anxious to speak to anyone who spoke to, engaged with or contacted Ms O'Hara either in person, by phone or email.
They have also appealed for information on her distinctive 05-D turquoise Fiat Punto, which they found parked at Shanganagh Cemetery in Dublin.
Along with clothes, handcuffs and leg restraints found at Roundwood, Co Wicklow, was a Dunnes Stores loyalty key fob that only had numbers on it.
Gardaí traced the fob to Ms O'Hara and they were subsequently able to identify some of the items they believe were dumped in the reservoir.
Superintendent David Taylor said the O'Hara family have been distressed by the level of media interest in the case.
He said while they are gaining some comfort from the discovery of her remains, they have appealed for privacy to be allowed time to grieve.
