Jason Van Dyke back in court Friday

CHICAGO — Chicago Police Officer Jason Van Dyke was back in court Friday.

A judge ruled that part of the hearing Friday and next week will be closed to all of the media. The judge says that is to protect the safety of witnesses.

Van Dyke’s defense team is expected to call witnesses who will testify about Laquan McDonald’s past. Van Dyke is charged with first-degree murder for shooting and killing McDonald in 2014.

Van Dyke’s next court appearance is May 10 at noon.
