Jonathan McCann, who lives near the house where the shooting is believed to have occurred, said he heard the gunshot but that there were no signs of commotion.
"This morning there was a bit of a bang … I didn't think much of it because there was no screaming or anything like that," he said.
"Came out about an hour and a half later, the coppers were walking around the yard and kicked the door in issuing a search warrant.
"No-one was home and the coppers were a bit dumbfounded that there was no one there."
