The father of a 17-year-old girl whose body was found in a trash barrel in the District last year was arrested Saturday and charged in her death, D.C. police said.

At a news conference late Saturday, Police Chief Cathy L. Lanier announced that Rodney J. McIntyre, 45, of Southeast Washington was charged in the death of Ebony Franklin. Police said he was charged on a warrant with first-degree murder while armed.

The girl had been fatally stabbed, police said. Her body was found Nov. 28 in a trash receptacle in an alley behind the 1000 block of Fairmont Street, in the Columbia Heights area of Northwest Washington.

Lanier declined to give a motive in the girl’s death.

Lanier said forensic and electronic evidence was gathered during the investigation. McIntyre had been a suspect since “very early on,” she said.

Police said he was taken into custody about 5:15 p.m. by members of the Capitol Area Regional Fugitive Task Force. It was not immediately clear where he was picked up.

The girl lived with her mother in the Capitol Heights area of Prince George’s County. Her mother had reported her missing late Nov. 27 and filed a report with county police.

However, it appeared that she had last been seen in the District.

Police said at the time she was found that she often visited her father in the District.

No street address was immediately available Saturday night for her father.

In answer to a question at the news conference, Lanier said there was “evidence of a sexual relationship” between father and daughter. The chief declined to elaborate.

The teenager was described last year as a student at Cardozo High School, about two blocks south of where her body was found.

However, published reports also suggested that she may have been enrolled at a high school in Prince George’s.
