U.S. District Judge David Ezra approved the agreement between federal prosecutors and lawyers for Delilah Williams in the battered-child death of Talia Williams in July 2005.

The agreement also calls for Delilah Williams to testify against her husband Naeem Williams, who is charged with murdering his daughter. Naeem Williams faces the death penalty if convicted. His trial is scheduled for May. It would be the first death penalty trial here since the 1950s when the Territory of Hawai'i abolished the death penalty.
