Rodney J. McIntyre, 45, had pleaded guilty in July to first-degree murder while armed in the death of Ebony Franklin, 17.
Franklin’s 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.
He pleaded guilty in D.C. Superior Court in July. As part of the plea agreement, prosecutors agreed not to file any additional charges against him.
McIntyre was sentenced by Judge Lynn Leibovitz. Franklin’s mother was one of many friends and family who attended the hearing Thursday, but she did not speak.
