Gardai investigating the murder of Kenneth O'Brien have renewed their appeal for information.
The 33 year old father of one disappeared last Friday, he left his house, having told his partner he was working outside Dublin that day.
His remains were discovered in the Grand Canal at Ardclough in Kildare the next day.
A group of young people walking near the Canal discovered a suitcase in the water, which transpired to contain Mr O'Brien's torso.
Now Gardai are renewing their appeal for anyone who was in Ardclough on Friday and early Saturday last to contact them.
They also want to speak to anyone who may have seen or had any contact with Kenneth last Friday morning, or can help in tracing his movements.
Gardai have searched extensively for the murder scene, but have yet to make a significant find.
Anyone with information is asked to contact the incident room at Leixlip Garda Station 01 666 7800.
