A Baltimore police officer charged in the death of Freddie Gray must testify against his colleagues while he awaits a retrial, Maryland's highest court ruled Tuesday, reports the Associated Press .
The Court of Appeals did not give any reason for the decision, saying it would issue an opinion later. The case was unusual because Officer William Porter's trial ended with a hung jury and as he was awaiting a retrial, a judge ruled he had to testify against some of the officers charged in the Gray case but not others.
