FLINT, Mich. (AP) — A judge has heard closing arguments, but it still could take weeks before Michigan's chief medical executive learns if she'll face trial in a Flint water case.

A special prosecutor wants Dr. Eden Wells to stand trial on an involuntary manslaughter charge in the death of a man who had Legionnaires' disease. She's also charged with obstruction of justice and lying to police.

Judge William Crawford must decide if there's enough evidence, a low legal standard at this stage. She denies the allegations.

Prosecutor Todd Flood wrapped up his case Monday, saying Wells should have done more to inform the public about a Legionnaires' outbreak in the Flint area in 2014 and 2015. Some experts have linked it to a change in Flint's water.
