I didn't say sister was the first person to tell OLHC that fr. Colletti was a laicised perv. Please read better, Cera.
You said that the reason Debbie was asked to leave OLHC (which was actually for her to stop begging at the chapel) was because she told Father Perez about Colletti. That's simply untrue.
No one knew about Colletti until Father Starbuck told us the truth. Many of those who heard the truth then asked Father Perez to get rid of Colletti. None of the others who complained to Father Perez about Colletti were asked to leave the chapel.
Obviously she was not asked to leave for the reason you say; the reason was her being a laywoman, yet presenting herself as a nun (with various names) and her non-stop begging. Let us pray for her.
