More Chicago police officers are expected to testify Wednesday in the Jason Van Dyke murder trial.
Tuesday, Van Dyke's former police partner, Joseph Walsh, testified. Walsh said that on the night of the shooting back in October of 2014, Laquan McDonald raised a knife toward them just before Van Dyke opened fire, even though dash camera video appears to show the opposite.
Van Dyke fired 16 shots at the teenager as he appears to be walking away from police.
Walsh faces his own criminal trial on charges that he conspired to cover up the shooting. He was given immunity from prosecution to compel his testimony Tuesday, as long as he gave it truthfully, and it could not be used against him in his own case.
He testified that he thought McDonald was a danger. Walsh asked not to appear on camera during the trial.
