Authorities in eastern Iowa’s Jackson County say the adoptive parents of a four-year-old boy are now charged in the child’s death.

Twenty-nine-year-old Danielle Lynn Holdgrafer, of Andrew, was charged Thursday with first-degree murder and 31-year-old Andrew Holdgrafer was charged with child endangerment resulting the death of a child, Colin Parker William Holdgrafer.

The boy’s death occurred last Saturday in what was initially called a drowning incident. The boy was adopted by the couple, who are his aunt and uncle. The boy’s mother is 30-year-old Jodi Holdgrafer, who is Andrew’s sister. She was sentenced to prison last year after various drug convictions in Dubuque County.

The couple’s other three children were removed from the home last Saturday night by the Department of Human Services and placed in foster care.
