The six Baltimore police officers charged in Freddie Gray's arrest and death will be tried separately over the course of the next several months, with proceedings against the first officer starting Nov. 30, reports the Baltimore Sun.

The new timeline, which pushes the trials back from a previously scheduled date of Oct. 13, was established during a hearing in Circuit Court on Tuesday afternoon, where five of the six officers appeared before Judge Barry Williams for the first time. The first officer to be tried waived his right to attend the hearing.

The delay was related to several issues, including new evidence being submitted in the case in recent weeks and the prosecution's desire to try the officers in a specific order — in part because some made statements about the others' actions during Gray's arrest and transport in the back of a police van in April, where he sustained a severe spinal cord injury.

The trials of the five other officers will occur between January and March.
