In the hours after Emmett Corrigan was shot and killed in a Walgreens parking lot in March 2011, Kandi Hall told Meridian police her husband and Corrigan got into an argument that ended with three shots.

She told police Corrigan was verbally aggressive, but said nothing about a physical confrontation.

Kandi Hall told an Ada County grand jury a similar story weeks later, prosecutors say, testimony that helped lead to Robert Hall being charged with first-degree murder.

On Thursday, testifying on the second day of Hall’s first-degree murder trial, she told an Ada County jury that Corrigan shoved her husband and almost knocked him down before the shooting.

Kandi Hall said she got between Hall and Corrigan and told them to stop, asked her husband to follow her to her car and started walking away.

“Today you are telling us Emmett Corrigan shoved your husband that evening?” Prosecutor Jason Spillman asked Hall. “Two hours after the shooting, when the incident was fresh in your mind, (you told police) that nothing physical happened between (Corrigan) and (Hall), is that right.”

“Things come back to me all the time,” Hall said.

Kandi Hall testified that she heard three shots — a pop, then a pause, then two more pops — and turned around to see her husband bleeding on the ground with Corrigan’s body a short distance away.

In the hours after the shooting, prosecutors say, Hall told police that the sequence of shots was pop, pop, pause, then the third pop. That earlier account supported the police theory that Hall shot and killed Corrigan because of the affair and then attempted to shoot himself in the head.

Prosecutors focused on Hall’s differing accounts during testimony, which lasted three intense hours and will continue Friday morning.

Another of those differences: Police say Hall, who is left-handed, had a graze wound to the left side of his head, indicating he tried to shoot himself. On Thursday, Kandi Hall told the jury she saw Hall holding the gun in his right hand after the shooting.

When prosecutor Jason Spillman suggested to Hall that she changed her story after talking to her husband when he was free on bond in the days following the shooting, Hall got indignant.

“I did not talk to him about what happened at the shooting, ever,” Hall said.

Robert Hall has pleaded not guilty. He told police in March 2011 that the gun fell out of his pocket during the confrontation and he wasn’t sure how Corrigan was killed. Even though she was called as a prosecution witness, Kandi Hall’s testimony felt more like a preview of Hall’s defense.

She spent most of the day telling the jury that Corrigan was aggressive, often angry, obsessed with the idea that she should leave her husband to be with him, and sent her repeated text messages and emails. Hall said she would never leave her husband of 18 years because she still loved him, even though she said she was being “selfish” and having a monthslong affair with Corrigan. She said she advised Corrigan not to abandon his wife and four kids.

Hall said the affair began about two months before she went to work as a paralegal at his law office in November 2010.

When the two men confronted each other at the Walgreens parking lot March 11, 2011 Hall said she didn’t say much.

“I was pretty much caught at that point ... what am I going to say?” she said Thursday. “I wasn’t going to leave my husband, didn’t want to lose my job, and didn’t want to lose being with Emmett.”

Hall said her husband was suspicious of Corrigan but didn’t figure it out until they argued in the parking lot.

She said Corrigan was a weightlifter and a fitness enthusiast, had a temper and was much stronger than her husband. So when they themselves in the Walgreens lot that night, she was afraid for her husband.

Hall is not a violent man, she said. That night he was more resigned and sad than angry, she said.

Hall admitted that her husband had a concealed weapons permit and regularly carried a handgun, but said she never considered he might be armed that day. “It didn’t even come into my mind,” she said.

In her testimony, Kandi Hall also told the jury:

• That she is committed to her marriage.

• Under questioning from prosecutors, she said she did not remember telling her husband shortly after the shooting, “I am going to make this better,” “This isn’t my first rodeo with the law, I know what I am doing,” or “I am going to get you vindicated.” Prosecutors did not say who reported those statements.

• She had sex with Corrigan twice on the day he was killed, once in Corrigan’s office and then in his truck about an hour before he was shot.

• She exchanged texts and emails with Corrigan saying they loved each other.

• She gave Robert Hall the handgun used in the shooting as a gift in 2009.

• Her husband and Corrigan had an argument outside the Halls’ Meridian home a few weeks before the shooting. They argued over text messages that Corrigan was sending Kandi Hall; she said she couldn’t hear what they said.

• She found her husband packing boxes in their garage the day of the shooting and said he told her that he was thinking of leaving her because of her behavior since going to work for Corrigan.

• She led a double life, trying to be a good mom and wife while carrying on a daily affair.

• She has pleaded guilty to grand theft for an unrelated criminal charge.

Kandi and Robert Hall occasionally looked at each other and maintained their composure for the first half of her testimony. Both broke down in tears when defense attorney Rob Chastain questioned Kandi Hall about why she was cheating on her husband.

“I don’t recall ever wanting to leave him ...” she said. “I love my husband.”
