Sun Roof Leak?

I have a 93 and the sun roof drains appear to work, but when it rains or washing the car, water collects on the passenger front carpet. Sometimes I will see a few drops coming off the headliner onto the dash or directly to the carpet.

Other times, I noticed that water appears to follow a path down the A pillar and soak the carpet.

Could there be a drain I am not aware of ? or is there a leak in the drain pipes?
