A Temple Hills teenager was sentenced to 50 years in prison Friday in the shooting death of a Prince George’s County high school student believed to be in a rival gang.

Akil Darnell Ings, 18, was found guilty in February of second-degree murder in the January 2013 slaying of 16-year-old Marcus Antonio Jones.

The shooting, which took place outside a birthday party in Fort Washington, was part of a spasm of violence that left six teenagers in the county dead in as many months.

Circuit Court Judge Maureen M. Lamasney gave Ings a sentence just under the 55-year maximum for his crimes. Prosecutors said she found his comments after the shooting, described by two witnesses as a boast of “I think I got one,” cold and callous.

“We’re satisfied,” said Principal Deputy State’s Attorney Tara Jackson. “We expect that Mr. Ings will be in jail for a very long time.”

Ings, who is appealing his conviction, did not speak at the brief sentencing hearing.

On Friday, his attorneys called for a new trial, based on the fact that one of the state’s witnesses has since been arrested on burglary charges. Lamasney denied the motion.

Police said they think that Ings belonged to a gang known as Baby Haiti and that Jones, a sophomore at Friendly High School, belonged to the Danger Boys, a rival group.

“We will not tolerate gang activity in the community or criminal activity related to gangs,” Jackson said, calling it “just unfortunate” that gang affiliation appears to have led to the deadly dispute.

A witness in the case, 19-year-old Kquantae M. Fisher, was fatally shot in his home in the fall. Police have not filed charges in Fisher’s death, but during Ing’s trial, prosecutors cited comments the defendant made to a then-girlfriend calling Fisher “the weakest link” that needed to be eliminated.

Jackson said that although “there is speculation” about Fisher’s death, authorities have not connected the two cases.
