A jury has been hearing about the final movements of murder victim Daniel McAnaspie.
Two Dublin men are on trial charged with the killing the 17-year-old at Tolka Valley Park, Blanchardstown three years ago.
Daniel McAnaspie’s body was found in a shallow grave in Meath in May 2010.
A farmer stumbled upon his decomposed remains and a post mortem found he had been stabbed in the heart, lungs, stomach and throat.
Gardaí believe a garden shears found in a river near where he was killed was used as the murder weapon
Richard Dekker and Trevor Noone are accused of his murder.
The men, who are both in their 20s and from Whitestown in Blanchardstown, deny the charge.
A jury at the Central Criminal Court has been hearing how Daniel was last seen alive with Dekker and Noone in the early hours of February 26, 2010.
Denise Kelly gave evidence today and described how she saw Trevor Noone punching Daniel over a comment he made about a relative of his.
The court also heard how Daniel was in state care at the time and was due to meet his carers hours before his death but didn’t keep his appointment.
The trial continues before Mr Justice Paul Butler at the Central Criminal Court.
