The Southeast Washington man accused of having a long-term incestuous relationship with his 17-year-old daughter and before stabbing her and dumping her body in a trash bin pled guilty Friday to first-degree, premeditated murder while armed.

In exchange for pleading guilty, prosecutors agreed not to charge Rodney J. McIntyre, 45, with any additional charges in connection with the slaying of Ebony Franklin.

Her body was found in a dumpster in an alley behind the 1000 block of Fairmont Street in Columbia Heights on Nov. 28.

A medical examiner’s report showed Frankln had been stabbed 15 times and McIntyre’s semen was found in her body. McIntyre was arrested and charged with his daughter’s murder in May.

Standing next to his attorney, Elizabeth Mullin of the District’s Public Defender Service, D.C. Superior Court Judge Lynn Leibovitz asked McIntyre if he understood the charges and agreed to plead guilty. “Yes ma’am,” he replied.

Prosecutors agreed to seek no less than 37 years in prison — and not more than 40 — for McIntyre. If McIntyre had gone to trial and was found guilty, he could have faced up to 60 years in prison for the murder charge.

The case stunned many in the Washington area. Assistant U.S. Attorney Jocelyn S. Ballantine said Franklin was raised by her mother in Capitol Heights and had reconnected with her father after he was released from prison in 2008.

Sometime after then, authorities said, the two entered into an incestuous relationship.
