FULTON COUNTY, Ga. -- A grand jury has indicted Atlanta attorney Claude "Tex" McIver on malice murder charges in the death of his wife.

McIver had originally been charged with misdemeanor reckless conduct and felony involuntary manslaughter in the September 2016 death of Diane McIver.

On Thursday, a Fulton County grand jury returned an indictment charging Tex with malice murder and six other counts, including three counts of efforts to unlawfully influence witnesses in the case.

On Sept. 25, Diane died after being shot while riding in an SUV near Piedmont Park. Her husband, a prominent attorney, said he was dozing in the backseat of the vehicle when his revolver fired. He has called the shooting "a terrible accident."

In December 2016, he was released on $200,000 bond, with conditions that included wearing of an ankle monitor, surrendering his passport and having no contact with anyone employed with Diane's business. At the time, he was also told he was not allowed to carry any weapons.

On Wednesday, a judge revoked Tex's bond after a gun was found inside his Buckhead condominium.

During the hearing, Fulton County prosecutors said that they believed Tex was hiding a secret will that his wife drafted prior to her death.

The new charges are as follows: murder, felony murder, aggravated assault with a deadly weapon, possession of a firearm during the commission of a felony and three counts of influencing a witness.

According to the indictment, Tex McIver is accused of instructing the woman driving the SUV at the time of the shooting, Dani Jo Carter, to tell authorities that she was not present when Diane was shot.

The indictment also states that McIver told Charles William Crane to retract a statement that Crane made to news media after the shooting. Crane had detailed the moments after the incident to 11Alive and other media outlets. (Click here for that story)

McIver is also accused of leaving a voicemail to Carter's husband on Oct. 6, implying that Carter should "cease communicating her recollections of the facts and circumstances of the death of [Diane McIver] to law enforcement officers, because said statements placed the defendant at imminent risk of immediate incarceration." McIver also allegedly requested that Carter's husband delete the voicemail.

As a result of the new charges, the grand jury issued a "no bond" warrant for McIver's arrest. He will be asigned to a Fulton County Superior Court judge within the next several days and appear for arraignment a short time later.

Diane McIver was the president of Corey Airport Services. Her husband was an attorney with the law firm Fisher and Phillips before retiring in December 2016.
