Final answer:
Detective Morrison may have sought assistance from agencies such as the U.S. Department of Health and Human Services and the National Archive of Criminal Justice Data to explore issues related to child safety and welfare.
Step-by-step explanation:
Other than the National Center for Missing and Exploited Children, Detective Morrison may have requested assistance from agencies that have a focus on children's welfare and safety. Two such entities include the U.S. Department of Health and Human Services, especially the Administration for Children and Families, and the National Archive of Criminal Justice Data, which provides resources like the National Crime Victimization Survey. These organizations work in collaboration to address issues of child maltreatment and provide support in cases involving missing and exploited children.
