Joel Johnson, charged in Brian Betts 2010 murder, killed in SE D.C.

A 21-year-old man killed while allegedly trying to commit a robbery Wednesday was one of four people charged in the killing of a popular teacher in 2010.

Police say Joel Johnson was shot and killed Wednesday in the 4200 block of First Street, SE during a robbery attempt.

Sources say Johnson and another man tried to rob a man and woman. The would-be robbers forced their way into a third floor apartment.

While inside,a struggle happened, and Johnson was shot by his intended male victim and later pronounced dead, police say .

Police say the other suspect fled, but on Saturday they arrested Jaren Holley, 21, of Northwest D.C., and charged him with burglary one while armed.

Police say criminal charges against the shooter have not been filed, but what happened is still under investigation.

A police source confirms to ABC7 that Johnson was one of the suspects charged with killing Brian K. Betts, who was slain in April 2010 in his Silver Spring residence.

Johnson in 2010 had pleaded guilty to accessory after the fact in connection with the killing of Betts.

Johnson did not have to serve most of his sentence and was released this past spring.

He was on probation and a warrant had been issued for him related to his probation two weeks ago.

Betts was a popular principal at Shaw Middle School in the District.

He was killed when Johnson and three other men came to his home after he had arranged to meet one of them he'd talked to on a sex chat line.

Authorities said the four came intending to rob Betts, but he was killed in the process.

Johnson was not responsible for the gunshot that killed him.
