Rodney McIntyre, who pled guilty to brutally murdering his 17-year-old daughter Ebony Franklin in July, has been sentenced to 40 years in prison. McIntyre, who was charged with the crime in May, received the maximum possible sentence.

The body of the 17-year-old Franklin was found inside an alley dumpster on the 1000 block of Fairmont Street NW last November. The charging documents against McIntyre described a crime of shocking brutality: Franklin was reportedly stabbed 15 times before being dropped in the dumpster, where police discovered her body three days after her death. After she was discovered, the U.S. Attorney’s Office revealed even more stunning details regarding the disturbing sexual behavior of McIntyre, and how he attempted to cover up the murder by sending “multiple text messages, including some directed to her stepfather that asked if her mother was upset that she had not come home.”

McIntyre was formerly employed at Meyer Elementary School, near which Franklin’s murder took place.
