On March 20, 2019, the independent Diocesan Review Board met and carefully considered the reports of investigators Scott F. Riordan and Steven L. Halter who were asked to investigate allegations of abuse against three priests of the Diocese of Buffalo.

As a result of these reports and the advice and recommendations of the independent Diocesan Review Board, Bishop Richard J. Malone has made the following determinations:

Based on the information at this time, an allegation of child sexual abuse against Rev. Ronald B. Mierzwa has been substantiated and he will remain on administrative leave while the results of the diocesan investigation are reviewed by the Congregation for the Doctrine of the Faith at the Vatican in Rome, who will make the final determination.

Based on the information at this time, allegations of child sexual abuse against Rev. John J. Sardina and Rev. Robert A. Stolinski have not been substantiated, and they have returned to active ministry.
