A Cleveland woman, Aliyah Henderson, pleaded not guilty on Thursday to more than two dozen charges after the remains of her two young daughters were discovered buried in suitcases.

The grisly discovery occurred on March 4 when Phillip Donaldson, a man walking his dog near a residential field, noticed a half-buried suitcase. “I pulled it up and looked in it, and it was a head. Somebody’s head in it,” Donaldson told WEWS-TV. He said the location was disturbingly close to a school.

Police identified the suspect as 28-year-old Aliyah Henderson, who was arrested and charged with murder, kidnapping, and abuse of corpses. The children were later identified as 10-year-old Amor Wilson and 8-year-old Mila Chatman, who were half-sisters. Henderson was given a $2 million bond and is eligible for the death penalty if convicted.

Video released by authorities shows Henderson’s arrest at her home. A third child living with her at the time was taken into the custody of Ohio social services. Attorneys for Henderson confirmed she entered a not guilty plea at her court hearing.

Investigators are continuing their examination of the case to determine the full circumstances surrounding the deaths of the two young girls.
