The Latest on the trial of a police van driver facing a second-degree murder charge stemming from the in-custody death of a 25-year-old black man (all times local):

12:10 p.m.

A judge says a detective can testify for the defense in the trial of a Baltimore police officer charged with murder in the in-custody death of a man whose neck was broken in the back of a police van.

Judge Barry Williams ruled Wednesday that prosecutors did not turn over material regarding the detective to the defense in a timely manner, and violated discovery rules.

The ruling means Detective Dawnyell Taylor could be called to testify by the defense. Taylor has notes about her conversation with Dr. Carol Allan, the assistant medical examiner who prepared Freddie Gray's autopsy report.

Allan has testified that she had an open mind about Gray's cause of death, but after reading the medical records and performing the autopsy, she determined his death was a homicide and not an accident.

Officer Caesar Goodson, the driver of the police transport wagon, faces second-degree murder, manslaughter and other charges stemming from Gray's death.

Gray's death last year sparked days of civil unrest in Baltimore.

Testimony will resume for the fifth day of trial for a Baltimore police officer facing a murder charge in the in-custody death of a man whose neck was broken in the back of a police van.

The wagon driver, Caesar Goodson, is facing second-degree murder, manslaughter and other charges stemming from the death of Freddie Gray.

Prosecutors say Goodson gave Gray a "rough ride" when he left him unrestrained by a seatbelt but handcuffed and shackled in the back of the wagon. Prosecutors also say Goodson was negligent when he failed to call for medical help.

Goodson's attorneys say the officer didn't give Gray a rough ride, and did nothing wrong.

The state has called 19 witnesses so far, and the defense has called two. Testimony will continue Wednesday.
