One resident said she heard her neighbour's dogs barking about the time of the incident and heard some noises but didn't check to see what was going on.
"I was awake but just stayed in bed and then I didn't know about what had actually happened until the morning when the road was blocked off," she said.
Another resident said the first she heard of the incident was also on Sunday morning when she saw the road cordoned off.
"We are still trying to work out what has happened," she said.
Mr Restieaux said there were also several parties in the area at the time of the incident so it was possible other people were out and about and may have seen or heard something.
