This "gutter" is a tube that goes from every corner of the sunroof.
The tubes in front go to the front wheel wells and the tubes in the
rear go to the vents at the top of the rear quarter panels.

A tube could have been knocked loose at either end enabling water to
leak inside, the rear window could have a leak, or a plug in the body
someplace could have rotted or been damaged and be allowing water to
come in.

This calls for some ingenuity!  Put plastic on the floor.  Does the puddle
collect on top of the plastic or under it?  Remove the carpeting, then the
back seat bottom, then the interior side panel, etc. until you can see where
it is coming from.  Have a friend help with a hose if it does not rain
enough.
