A Baltimore judge will hear motions Wednesday from prosecutors who want to force an officer to testify against four other officers charged in the police custody death of Freddie Gray.
Prosecutors are asking Baltimore Circuit Judge Barry Williams to force William Porter to testify against four officers even though Porter's charges are still pending after his own trial ended in December with a hung jury.
Williams ruled in late December that Porter must testify against Caesar Goodson, whose trial was slated to begin last week. Goodson drove the van that transported Gray, a young black man who died April 19, 2015, a week after he broke his neck in police custody.
Goodson was with Gray for throughout his 45-minute trip from the site of his arrest to the Western District police station, where Gray arrived critically injured and unresponsive.
But Goodson's account of what happened that day remains a mystery: He is the only one of six officers charged in Gray's death not to speak to investigators.

His trial has been postponed indefinitely while an appeals court decides whether to uphold or overturn Williams' ruling.
Gray's death exposed the deep divide between the public and the police in Baltimore, and became a national symbol of the Black Lives Matter movement.
