Gardaí investigating the death of Ms Lynette McKeown (19), from Tallaght, Dublin, have renewed their appeal to a man who contacted them last week about the case get in touch again.
Gardaí believe that the man had has "vital information" and are anxious to speak to him. He made a telephone call to gardaí in Dublin before Ms McKeown's body was found on Saturday 22nd.
Meanwhile, gardaí would not confirm that two public telephone boxes in Santry, north Dublin, were sealed off on Wednesday for forensic examination.
It was reported that calls were made from these boxes early on Wednesday morning from a person claiming to have information about the case.
He said that the force did "not discuss operational matters".
Gardaí are still awaiting toxicology tests, including those for drugs and poisons, which could take another week before they are completed.
Thirty detectives are investigating the death of Ms McKeown, whose badly decomposed body was discovered at a derelict house at Eadestown, Co Kildare, last Sunday. Gardaí believe that her body may have been there for at least six days given the degree of decomposition.
The mother of a two-year-old daughter was formally identified two days after a farmer found her body.
A murder investigation has not yet been launched because the post-mortem examination was inconclusive in establishing the cause of death.
