Calif. Equestrian Who Hired Hitman to Kill Husband Dies by Suicide Shortly After Prison Release

A California equestrian convicted in a plot to have her estranged husband killed has died by suicide, the San Diego County Medical Examiner’s Office confirmed.

Tatyana Remley died on Dec. 18, 2025, from a gunshot wound to the head. The medical examiner ruled her death a suicide.

Remley had been convicted in a murder-for-hire case involving her estranged husband, Mark Remley. NBC San Diego reported in December 2023 that she pleaded guilty to solicitation to commit murder and received a sentence of three years and eight months in state prison.

She was arrested in 2023 after allegedly meeting with an undercover officer and offering to pay for her estranged husband’s killing.

Investigators began looking into the case after a house fire at the couple’s ranch property in Del Mar, an unincorporated area of San Diego County north of San Diego, according to the San Diego County Sheriff’s Department.

Deputies said an arson unit responded to the scene and that Remley was initially arrested that day for alleged firearms-related offenses after officers said they found three firearms and ammunition in her possession.

The next day, the sheriff’s department said investigators opened a murder-for-hire inquiry after receiving information that Remley was trying to hire someone to kill her estranged husband.

“She provided detailed information on how she wanted her husband killed and his body disposed of,” the sheriff’s department alleged in a statement. Authorities also claimed Remley brought firearms and U.S. currency as a down payment.

According to The Coast News, Mark Remley told the outlet that his wife had offered a mutual friend $2 million to kill him. The friend declined and alerted police, prompting a sting operation, the outlet reported. The outlet also reported that Remley later met with an undercover officer at a local Starbucks.

In divorce papers, Remley said she and a friend were at the property when the fire broke out but claimed she did not know how it started, The Coast News reported. Her husband, however, told the outlet that he believed the fire was intentionally set after he allegedly discovered she was trying to have him killed.

The Remleys married in 2011 and separated and reconciled multiple times over the years, according to The Coast News.

Remley was charged with arson in connection with the house fire and was arraigned on Sept. 11, per a criminal complaint shared with the San Diego County District Attorney’s Office. She was scheduled to return to court on March 3, 2026, per the office.

An attorney for Remley and her estranged husband could not be reached for comment at press time.
