Testimony continues in Tyler McCain’s preliminary hearing, who’s accused of killing his wife, Nikki McCain.

On Tuesday, Luis Barajas took the stand at the Shasta County Superior Court in California, continuing his testimony from last week, and talked about his alleged romantic relationship with Nikki, according to ABC 7.

Barajas recounted that they were together on May 17, 2024, the last day Nikki was seen. Their communication, which was frequent and included texts and calls, abruptly halted on May 18, he said, following an argument.

As CrimeOnline previously reported, the Redding Police Department said Nikki last spoke to her family On May 17, 2024, before someone picked her up from a home in Redding, near the Win-River Casino.

Her truck was also reported missing, but police later found it, a 2002 Chevrolet Avalanche with California license plate DP154UT, on May 25, 2024, in western Tehama County, according to the Shasta County Sheriff’s Office.

Shasta County authorities later reclassified Nikki’s disappearance as a homicide, and charged Tyler McCain with the murder last month.

Shasta County District Attorney Stephanie Bridgett said that Tyler McCain’s motive had been to keep Nikki, a mother of four, from testifying against him in a domestic abuse case.

Nikki’s body has not been found, and the prosecution has relied on forensic evidence, such as blood in the truck and recorded statements, to establish probable cause.

When questioned by the prosecution, Barajas denied having any involvement in Nikki’s disappearance.

Last week, Barajas told the court that he met Nikki when he worked at an Anderson phone store. He claimed Nikki told him she planned on divorcing Tyler.

Barajas also said that Nikki told him that her husband tortured and beat her.

Tyler McCain’s mother, Jeanette Hayward, also testified Tuesday. She claimed that alcohol use affected her memory of events around the time Nikki vanished.

She admitted to drinking heavily—about a pint of vodka daily—which she said impaired her recollection.

Hayward did, however, recount that Tyler called her in May 2024 to pick him up in Red Bluff following an incident with the couple’s Avalanche.

During questioning, she appeared uncertain about many details, often responding, “I don’t recall.”

The prosecution challenged her on her memory lapses, alleging that Hayward discussed case information with her daughter, despite a court order prohibiting witnesses from sharing details.

Carolyn Heitaman, a forensic analyst with the Department of Justice, also took the stand Tuesday.

She testified regarding the DNA analysis of several items, including a white sheet found in the Avalanche. She said multiple DNA profiles were found on the sheet, including from Nikki, Tyler, Luis, Tyler’s cousin, Larry Flolutz and a man who lived on the McCain property, Justin Karren.

Luis Barajas admitted on the stand that he had sex with Nikki the night before she disappeared, and that they used a white sheet to throw over a couch.

The sheet had three corners tied into knots, each containing different DNA samples. Most crucial was the blood and hair evidence, which predominantly matched Nikki’s DNA, Heitsman said.

Additional testimonies are expected as the hearing continues. The prosecution stated that the hearing is expecting to conclude on Thursday.

Tyler McCain has pleaded guilty to the charges against him.
