Judge: Statements by Chicago officer to detective admissible

A judge says statements a Chicago police officer made to a detective shortly after fatally shooting a black teenager can be used by prosecutors at the officer's murder trial.

The judge ruled in the case of Jason Van Dyke, who is charged with first-degree murder in Laquan McDonald's 2014 shooting. Van Dyke and the detective — who was charged Tuesday with conspiring to obstruct justice to help Van Dyke — both testified Wednesday.

The Chicago Sun-Times reports that Van Dyke's lawyers argued he had been forced to answer questions that might incriminate him. Van Dyke told the judge he only gave statements because he believed he'd be fired if he didn't.

Now-retired Detective David March testified he never told Van Dyke he'd be disciplined for refusing to speak.
