The jury at the Dale Cregan trial earlier heard that the gun used to shoot David Short was used to murder PC Fiona Bone and PC Nicola Hughes.
Prosecutor Nicholas Clarke QC said bullets recovered from Mr Short's body were found to have come from a Glock-type pistol following tests. He told the jury:
This was the Glock that Cregan would use again, on the 18th September, 2012, when he murdered PC Fiona Bone and PC Nicola Hughes.
The trial will resume on Friday morning after being adjourned this afternoon.
