Heartbroken relatives of a mother-of-four, missing for over a year, have expressed their anguish and frustration after her husband was arrested in connection with her murder, with police revealing his purported motive.

Nikki Cheng-Saelee McCain was last seen on May 17, 2024, visiting a relative in a hospital in Redding, California. She returned to her husband, Tyler McCain, but the 39-year-old ceased responding to texts and calls by the next day and was reported missing by her sisters four days later.

Her Chevrolet Avalanche was found abandoned on a roadside 30 miles from her home on May 25.

Nikki’s family feared the worst from the start. Her disappearance happened just two weeks before McCain’s scheduled court appearance for four domestic violence charges. Nikki was expected to testify against him, but the charges were dropped following her disappearance.

Her sisters, Chloe Saelee and Kaye Saelee Ford, waited in agony as the months passed without updates.

A turning point occurred on Wednesday when prosecutors announced McCain had been indicted for Nikki’s murder, revealing evidence that prompted his arrest for the first time.

Shasta County District Attorney Stephanie Bridgett told reporters that McCain allegedly killed Nikki to prevent her testimony against him and subsequently hid her body at an undisclosed location.

Investigators discovered a strong odor of decay in Nikki’s truck and found a bloodstained sheet in the truck bed. McCain is also said to have confessed to an unknown individual that he murdered Nikki during a domestic violence confrontation on May 18, 2024, Bridgett shared.

For Nikki’s siblings, the details were hard to hear but ratified what they’d suspected all along. What infuriates them, they told the Daily Mail, is how little value McCain seemingly placed on their beloved sister’s life.

‘Throughout this, I’ve always taken a matter-of-fact approach to the details, separating the facts from my personal feelings and emotions,’ said Kaye. ‘But hearing about the blood, the DNA, the decomposition, and knowing that was confirmed to be my sister, that was so emotional.

‘But it’s also given me confidence. This evidence is just the tip of the iceberg, and I know that they have even more evidence that is stronger and that will make sure he’s convicted.’

The family said police confirmed their suspicion that McCain killed Nikki over the prospect of facing jail time for domestic violence.

They described the motive as shockingly trivial – the possibility of a short jail sentence – compared to the value of her life.

Even though they knew nothing could ever justify her sister’s killing, they almost hoped there might be a deeper explanation. But the fact that there wasn’t has left them furious and sickened.

‘To think her life was just worth so little to him, that he felt entitled to kill her because he wanted to avoid a little bit of jail time, is just disgusting,’ said Kaye.

‘This is someone who has children, who was part of our family… It’s unimaginable to think that someone we knew could not only be capable of something like this, but also be so cold about it.

‘Clearly, we never knew him at all; the person we saw was just a facade.’

McCain’s arrest came five months after police, along with the FBI and Homeland Security, served a search warrant at the home he shared with Nikki in Anderson.

After that search, investigators ruled that Nikki was the victim of a homicide but declined to release further information at the time.

McCain had broken his silence for the first time only four days earlier at a press conference, saying at the podium: ‘I’m just here in support, so anything that I can do, I want to do that […] I haven’t been in the public eye, and I haven’t done very well with it. I apologize to everyone, especially my children.’

He also shared a brief message for Nikki, saying simply: ‘We miss you.’

With McCain now behind bars, the attention for Nikki’s family shifts to finding where her body was dumped so they can bring her home and finally lay her to rest.

Until then, the family says they will never be able to achieve any semblance of closure or move past the nightmare of the last 16 months and counting.

Exhaustive efforts have already been exerted to find Nikki, but each search has so far come up empty.

Chloe and Kaye believe McCain can help end their suffering, and the suffering of his and Nikki’s four young children.

‘You took her away from us, and now it’s time to do the right thing. You at least owe us that,’ shared Chloe. ‘Just tell us where she is.’

Kaye added: ‘We want closure not just for us, but for their children. They’re in the most difficult position, because they’re divided between the love they have for both parents.

‘It’s important for them to be able to mourn their mom properly and lay her to rest. That’s important for all of us, but especially them.’

An attorney for McCain has not returned a request for comment.

He is currently being held without bond at Shasta County Jail.

McCain has been charged with murder. Prosecutors said they would pursue a special circumstance allegation that he killed Nikki to stop her from testifying.

Prosecutors said they will also refile domestic violence charges that were dropped last year. Those counts included corporal injury to a spouse, false imprisonment, criminal threats and assault with force likely to cause great bodily injury.

McCain will also be charged with possession of a firearm and ammunition after a criminal protective order, forgery, and various traffic violations, prosecutors said.

Investigators said there were allegations of domestic violence against McCain dating back to 2020.

Chloe previously told the Daily Mail that her sister’s relationship became increasingly toxic and tumultuous during the pandemic.

In December 2023, Nikki was hospitalized with severe injuries she said were inflicted by McCain. Her sister Chloe, who accompanied her, recalled barely recognizing her.

A deputy noted Nikki’s eyes were both blackened and swollen, and her face showed extensive trauma. Nikki told him her husband had attacked her the night before in a violent outburst.

She said McCain came home in a strange mood, locked the doors, and suddenly jumped on her, pinning her to the ground. 

He dragged her, pulled her hair, and repeatedly struck her in the face, she claimed. Nikki described his eyes as ‘glazed’ and ‘scary,’ and said she believed he intended to kill her.

At one point, she alleged, he tried to wrap something around her neck to choke her. After three hours, Nikki escaped while McCain was in another room and fled to the hospital.

McCain denied assaulting her, instead suggesting she had been in a fight with another woman. He later gave conflicting statements, at first claiming Nikki was having an affair and then insisting their relationship was happy.

He was arrested and charged with four felony counts of domestic violence. He pleaded not guilty. The case was dropped in July 2024 after Nikki’s disappearance, a decision that sparked outrage in the community.

On Wednesday, Sheriff Michael Johnson said McCain’s arrest came as a result of rigorous police work conducted by numerous agencies.

However, he emphasized their work is only half done. 

‘Nikki is still not home,’ said Johnson. ‘Nikki is still out there somewhere, and we want her back. And if you’re watching and you have information and you know where she is, please come forward.’
