Northampton man David Miller was killed with a stab wound to his aorta, tests have shown.
Mr Miller’s body was found at his home in Patterdale Walk, Boothville on Tuesday and the court heard he may have been killed the previous day.
Jonathan Straw, prosecuting, said that the fatal injury was a single stab wound that pierced his aorta but there were also other injuries to his body.

All matters were adjourned until a trial, which is set to take place in November.
