By BILLIE STANTON ANLEU billie.stantonanleu@gazette.com -About 100 people filed solemnly into St. Paul's Catholic Church on Monday morning for the funeral of Ksenia Quiros, who is thought to have committed suicide after her Air Force Academy cadet son died in his dormitory room April 2. The fragrance of incense wafted across the pews as Jose and Peter Quiros, her widower and youngest son, laid an embroidered cloth across her casket at the sanctuary entry. Among those paying their respects were three uniformed Air Force officers and perhaps a dozen boys who appeared to be of junior high age, as is 14-year-old Peter. Also on hand was Pedro Quiros, Jose's father, who flew in from Costa Rica to be with his son and namesake grandson.
