A Lurgan man, found dead in his flat, had his head stamped on, the High Court was told.
Prosecutors said Marcell ‘Junior’ Seeley (34) suffered blunt force trauma in the attack, with footwear patterns on his body indicating the type of blows inflicted.
It was also claimed that the man charged with his murder is linked by DNA on a cigarette butt discovered at the scene.
Mark Daniel Ward (24) from Drumellan Gardens in Craigavon denies carrying out the killing.
He was refused bail last week due to concerns that he would not comply with release conditions.
Mr Seeley was found dead in his home at Dingwell Park, Lurgan on on October 13.
Police believe he was killed at some point in the preceding four days.
A post mortem examination established that he sustained head injuries, including severe bruising and lacerations and fractured ribs.
Fiona O’Kane, prosecuting, told the court the blows were consistent with Mr Seeley being kicked, punched or a combination of both.
Bruising patterns on his body also suggested he was stamped on, she said.
Mrs O’Kane said police suspect that Mr Ward had worn distinctive footwear with similar markings.
She said he was seen at Mr Seeley’s home before going to a neighbour and remarking ‘Junior, two uppercuts and one to the right’.
A cigarette butt was recovered from the victim’s flat was said to have a DNA with Mr Ward.
Eugene Grant, defending, argued that witness statements contained inconsistencies.
He said no definitive time of death had been established, and challenged the DNA connection to his client.
“Footwear is notoriously tenuous evidence unless there is a striking similarity,” he said.
Lord Justice Weir denied the bail application.
“There’s a well-developed concern that if released he wouldn’t comply with bail conditions,” he said.
