The father of missing 6-year-old Isabel Mercedes Celis gave a heartfelt performance at a benefit concert Sunday night, bringing to tears many of those in attendance.
Sergio Celis, an opera singer, sang Ave Maria to the crowd of about 100 people gathered at Catalina United Methodist Church in central Tucson.
The benefit was organized by friends of the Celis family to raise money in the search for Isabel, who was reported missing from her home April 21.
Police continue sifting through hundreds of leads in the case, but have not identified a suspect or motive in the child's disappearance.
After Sergio's performance tonight, he blessed himself with the sign of the cross and returned to be seated with his family.
