T. Gerald Treece, a longtime friend of the late John M. O’Quinn, has filed a petition to resign as executor of O’Quinn’s estate after serving in that role since shortly after O’Quinn died in an automobile accident in October 2009.

In an amended petition filed June 21 in O’Quinn’s probate case, Treece, vice president and associate dean of advocacy at South Texas College of Law Houston, said that he wants to resign even though the administration of O’Quinn’s estate is not concluded because of outstanding claims still pending due to litigation. Treece filed his original petition to resign June 5.
