UPDATE: (12/21/16) - The thirteenth person charged in the Flint water emergency arrived in court to face a judge on Wednesday.

Darnell Earley is arguably the biggest name charged so far, one of two emergency managers now facing the possibility of prison time for lead-tainted water in the city.

Ambrose turned himself in Tuesday afternoon, along with two former Flint administrators - Howard Croft and Daugherty Johnson.

All three men Tuesday said they're not guilty.

(12/20/16) - ABC12 News has learned former emergency managers Darnell Earley and Jerry Ambrose along with former Flint public works direction and his employee Daugherty Johnson are being charged in connection to the Flint water emergency.

Earley and Ambrose have been charged with multiple 20-year felonies for their failure to protect the citizens of Flint from health hazards caused by contaminated drinking water.

Croft and Johnson also face felony charges of false pretenses and conspiracy to commit false pretenses related to their roles in a process that led to the issuance bonds to pay for a portion of the KWA water project.

All are charged with: False Pretenses, Felony: 20 Years and/or $35,000, or 3 times the value of the money or property involved, whichever is greater.

Attorney General, Bill Schuette, says they put dollar signs above the health of Flint's people.

"This fixation with money came at the expense, came at protecting the health and safety of protecting Flint. It was all about numbers over people, money over health," Schuette said.

Earley and Ambrose allegedly claimed there was a so-called 'environmental calamity' happening in the city in 2014 in order to get $85,000 in loans to pay into the KWA pipeline project.

The reason the two claimed there was an emergency was because otherwise, the Department of Treasury wouldn't let the city borrow money while it was in serious debt.

Schuette says there was no emergency at the time - it was a

bait-and-switch maneuver.

Schuette says in that agreement with the state there was a clause forcing the city to switch to the Flint River as its drinking source and use the Flint Water Treatment plant, even though the plant wasn't equipped to treat the water properly. He says there wasn't a corrosion control plan in place.

ABC12 News asked Mayor Karen Weaver about the charges. She says she's happy there's some accountability with Flint's water emergency and not surprised at the names.

"Profit was put over the health and the well-being of the people. And this really gives voice to that," Weaver said.

Weaver said it seems like everybody knew what was going on, but nobody spoke up. She talked to us about criminal charges that could still come.

"Well I think it's going to go higher, I think they'll do just what they said they're going to do, they're going to continue to investigate and they're going to bring some more names forward," she said.

Some of the names and faces may be familiar to you - some may not.

Darnell Earley was emergency manager from September 2013 to January 2015. The city switched water sources during his tenure - from Detroit to the Flint River. Of course this later resulted in pipes corroding from untreated water and lead leaking into the city's drinking water.

Jerry Ambrose took over as emergency manager in January of 2015, until April of 2015. Ambrose was a staunch defender of the quality of Flint's water - despite complaints from residents. Emails later released from the state show Ambrose was warned by the county health department of a potential Legionella crisis.

Howard Croft was head of public works in Flint from December of 2011 until November of 2015. He had also defended Flint's drinking water quality. Croft has been quoted as saying the decision to switch to the Flint River was a financial one and the order to do so came directly from Governor Snyder's office.

Finally, Daugherty Johnson, who was Flint's utilities administrator at the time of the switch-over. Johnson, a former union leader, wrote in emails released from the state that Flint had done extensive upgrades to the water treatment plant and wanted the facility to be the primary drinking water source for the city. The day after the email was sent to the MDEQ, it became official and the city switched to the Flint River.

We asked Flint residents at the Farmers' Market what they think about the charges.

"It has to keep going. It's great they've been doing that and I wish it was a quicker process,” said Erin Coney.

"I think because the emergency managers really took over what was happening in the city I don't think the city should be blamed for it to tell you the truth. Because the buck stops with what the government wants, the state government. I think they need to go higher up,” said Shane Burton.

"There are so many of us that are paying the price for somebody else's bad choices. And the way it looks, it's going to be years to come. How long can you wash your baby in a bathtub with bottled water? How long is that going to last?" said Sandra Weston.
