Smithman was not going down narrow lanes or brightly lit steps that he'd never used before. He knew how to get to his destination so he reached the church IMO - you follow that road and it takes you there. Go past the church and derelict house and it leads you to Kate's rocks.
Do you mean the Rocha Negro ? Pat Brown went on about it intimating that it had a special significance to Kate and Gerry.

Pathfinder , even if Smithman WAS going towards the church, he had almost a mile to go to Rocha Negro !
And he was going in the opposite direction to the route he originally chose.
Have you been up there, to that volcanic outcrop? It is one hell of a climb and would be a bit uneven in the dark. I had a lift part way up, then gave up on the flat area about half way up.
Heri has a very good analysis and vector diagram showing the likely direction that he weas heading for >.. and it certainly wasn't Rocha Negro

With Rocha Negro the best part of a mile to the east, dont think he was heading there tbh,
