FLINT, MI (AP)-- Not-guilty pleas have been entered by three of the four people newly charged in the Flint water investigation.
Gerald Ambrose, Howard Croft and Daugherty Johnson briefly appeared in court Tuesday. They are charged with conspiracy and other crimes.
Ambrose is Flint's former state-appointed emergency manager. Croft is Flint's former public works director, and Johnson is the former utilities director.
They're all accused of keeping Flint on Flint River water and using a water treatment plant that wasn't ready for service. The water wasn't treated to control corrosion. As a result, lead leached from pipes and old fixtures.
Former Flint emergency manager Darnell Earley also is charged. He hasn't appeared in court.
