Gardaí have taken away number of items from the house of murdered Waterford woman Meg Walsh.
Gardaí sealed off the two-storey detached house saying it was a possible crime scene.
The office worker (35), from Waterford, was missing for two weeks before her battered naked body was found floating in the city's quays on Sunday afternoon.
The items from the house were sent for analysis to the Garda Forensic Science Laboratory in Dublin.
The head of the investigation, Supt Dave Sheahan of Waterford Garda Station, said today officers were still searching for a murder weapon.
"At this point in time, it is too early to say what type of weapon was used in this killing," he said.
"We are considering a number of options but we will have to consult further with the State Pathologist to determine how this death occurred."
Gardaí continued to distribute flyers around Waterford city with descriptions of Ms Walsh and her 01 W 2060 registration car.
Ms Walsh shared the house in Ballinakill Downs with her husband, John O'Brien.
No arrests have yet been made in the murder investigation, but gardaí will make a fresh appeal for information this afternoon. Officers are still searching for Ms Walsh's car keys, her key fob and her Motorola Razr V3 mobile phone, which is black and grey in colour.
Telecoms experts had been trying to trace a signal from the handset but were unsuccessful. It is understood that Ms Walsh, originally from Fermoy, Co Cork, had previously told friends she felt in danger and had made an assault complaint to gardaí.
Gardaí carried out a reconstruction of the movements of Ms Walsh's Mitsubishi Carisma saloon car last night in a bid to jog the memories of local people.
Motorists and pedestrians were also stopped and interviewed on the Dunmore Road between Ms Walsh's house and where her car was later found almost a mile away in the Ardkeen area of the city.
Officers are keen to discover where the vehicle was between 7am on Sunday, October 1st and October 4th, when it was discovered at the Uluru car park at 1am.
