Updated at 2:08 p.m. ET: Andrea Sneiderman, the widow of a businessman who was gunned down by her former boss outside a Georgia day care center, was charged Thursday with murder and other crimes connected to the slaying.

Prosecutors contend she conspired with her then-supervisor, with whom she was allegedly having an affair, to have her husband killed so she could collect on $2 million in life insurance policies.

A team of Putnam County and DeKalb County law officers went to Sneiderman’s home in Eatonton, Ga., and took her into custody Thursday morning.

The arrest occurred after a DeKalb County grand jury returned an indictment on charges of malice murder, attempted murder, racketeering, insurance fraud, two counts of perjury and two counts of making false statements.

DeKalb County District Attorney Robert James announced the charges at an afternoon press conference but refused to elaborate on the nature of the evidence.

"Our collective goal is to continue to seek justice and preserve the public safety of our community, not only for the Sneiderman family but for anyone who has lost a loved one because of a violent crime," he said.

James said the arrest was the result of several months' work. "We’re going to put all the facts and the evidence out there and at the end of the day it’s going to be up to a jury to make a decision in this case," he said.

Sneiderman, a 36-year-old mother of two, was booked Thursday into the DeKalb County Jail. She will likely be arraigned within the next month, James said.

Sneiderman's attorney, J. Tom Morgan, said she "categorically" denies the charges.

"There's no way we can know what evidence was presented in secret chamber. That's why we have juries, and people who know nothing about this case will be able to make a decision at that time," Morgan said.

Rusty Sneiderman was shot to death on the morning of Nov. 18, 2010, after he dropped off his son at a Dunwoody day care facility.

The case drew national attention after authorities arrested Hemy Neuman, Andrea Sneiderman's boss at the General Electric complex in Marietta, and charged him with the slaying.

At trial earlier this year, Neuman was found guilty but mentally ill after acknowledging he shot Rusty Sneiderman multiple times.

Prosecutors contended Neuman and Andrea Sneiderman were having an affair and Neuman wanted to get rid of his romantic rival. Andrea Sneiderman testified that they never did more than hold hands.

Neuman is serving a term of life without parole at the Georgia Diagnostic and Classification Center in Jackson.

In June, Andrea Sneiderman filed a wrongful death lawsuit against Neuman. She formally denied being his co-conspirator and said in the lawsuit that Neuman acted alone.

The indictment returned Thursday against Andrea Sneiderman alleges she plotted with Neuman to have her husband killed so she could acquire his money and property. Rusty Sneiderman had two life insurance policies with a combined payout value of $2 million and individual and joint accounts totaling more than $960,000.

“Neuman and Andrea Sneiderman conspired together to murder Rusty Sneiderman so that they could enjoy a life together, eliminate Neuman’s debt problems, and fully benefit from the assets the Sneidermans had acquired as well as the proceeds of Rusty Sneiderman’s life insurance policies,” the indictment says.

During their affair, Andrea Sneiderman and Neuman took business trips together and Neuman asked her to be with him forever and to marry him, prosecutors allege.

On the morning of the slaying, Neuman disguised himself with a fake beard, drove to the Dunwoody day care in a rented van and shot Rusty Sneiderman four times with a handgun.

Andrea Sneiderman collected on the death benefits of her husband’s life insurance policies a few months after the murder, according to the indictment.

DECATUR, Ga. -- A corporate engineer was found guilty but mentally ill Thursday of killing the husband of a woman with whom he allegedly was having an affair and sentenced to life in prison without possibility of parole.

Hemy Neuman was accused of gunning down Russell Sneiderman on Nov. 18, 2010, as the victim was dropping off his son at a Dunwoody day care. Prosecutors and defense attorneys said Neuman was having an affair with Sneiderman's wife, Andrea, although she denied those allegations.

DeKalb County Superior Court Judge Gregory Adams called the shooting a "planned execution."

 

Neuman, a Georgia Tech graduate and father of three, was a high-ranking manager at General Electric, where he supervised Andrea Sneiderman. He was arrested about six weeks after the killing when prosecutors discovered he rented a silver minivan seen speeding away from the shooting scene.

The trial garnered attention because the slaying was brazen, Neuman and Sneiderman had impressive professional backgrounds. and there were questions surrounding Andrea Sneiderman, who was accused of goading Neuman into the killing by both prosecutors and defense attorneys.

She denied knowing anything about the shooting and has not been charged.

The "mentally ill" designation means Neuman will receive mental health treatment in prison.

During sentencing, Neuman told the judge the shooting was a terrible tragedy.

"I am so, so, so sorry. I can't say it enough ... I am sorry from the deepest part of my heart, your honor," Neuman said before his attorneys urged the judge to give him life in prison with parole.

Neuman pleaded not guilty by reason of insanity. If the jury had reached that verdict, Neuman would have become a ward of the state mental health department and a judge would have later decided when, if ever, he could be released.

Neuman told mental health examiners he was visited by a demon whose voice sounded like Barry White and an angel who looked like Olivia Newton-John. The angel ordered him to fatally shoot Sneiderman, Neuman said in one interview.

The defense team said it would appeal.

Neuman's lawyer, Doug Peters, told the jury in closing arguments Tuesday that his client did indeed shoot Sneiderman. But he said Sneiderman's wife fed Neuman's dangerous delusions by encouraging him to believe he needed to kill her husband to protect her two children.

"The gun in this case was in Hemy's hand," Peters said. "But the trigger, I respectfully suggest, was pulled by Andrea Sneiderman."

Asked Thursday if Andrea Sneiderman will face charges in her husband’s death, DeKalb District Attorney Robert James said: "It is something we have under review right now. It's something we're looking at,” The Atlanta Journal-Constitution reported.
