Need help with a capturing a cat

[u/bassmnt]

My good friend had taken in a feral kitten. He had him in his finished basement. Then he passed away suddenly. The cat has found a hole to get into a section of the pipe run in the ceiling. His daughter can't get him to come out to capture him to find a new home.

Food and a litter box is there, and they are using it. However, whenever someone goes down, they hide.

Can anyone offer any advice, short of cutting the ceiling open?

edit to add:
Everything has been tried.
The cat will come out and sneak peak at the daughter, but runs back if she moves towards.
It's a railroad style brownstone. The hole is in the ceiling at the rear wall.

At this point, unless there's a cat whisperer out there. I think the only recourse is a trap or cutting a hole(s) along the space they are in.
