Missing mother of four Suzanne Clark Simpson told her own mom just an hour before she vanished that her husband had physically abused her, according to the parent who fears her daughter is dead.

Simpson, 51, has not been seen or heard from since Oct. 6 when she and her property tycoon husband, Brad Simpson, allegedly got into a shouting match.

“Suzanne and I had an opportunity to talk an hour before a lot of this has happened,” Simpson’s mother, Barbara Clark, said at a vigil for her daughter on Sunday night.

She called me up and told me the things that Brad had done to her physically,” Clark said, suggesting the violence was “alcohol-related.”

Suzanne said that around 9 o’clock that night, Brad Simpson had hurt his wife’s arm and back, according to KSAT.

The worried mother immediately came up with a plan to get her daughter out of the house, she said.

“I came up with an alternative plan for her that she would move in with me and have her little toddler go to the elementary school in my neighborhood,” Clark said.

“I never got to tell her the plan.”

Clark said that although the family is trying “to be positive,” they do not believe Simpson is still alive.

“I don’t think she is because I have not heard from her,” the alarmed mom said.

Brad Simpson, 53, was arrested on Wednesday and charged with assault causing bodily injury – family violence and unlawful restraint.

He is being held in Bexar County jail, where he has been uncooperative with investigators, police previously said — further distressing his mother-in-law.

“I would like to visit him and ask him why. What happened?” Clark said at Sunday’s vigil.

Simpson had attended a party at The Argyle, a private dinner club in nearby Alamo Heights a few hours before she disappeared.

A neighbor witnessed Suzanne and Brad fighting outside of their home between 10 and 11 p.m., according to police.

Brad was “clearly attempting to keep Ms. Simpson from running away,” police said.

The witness said the married couple walked away into the woods together. The neighbor went outside with a flashlight to investigate but ran back inside after hearing “two to three screams” coming from the darkness.

An hour later, Brad left the house in his pickup truck and returned between two and three hours later, the neighbor said. 

Brad initially reported his wife missing on Monday — but has been uncooperative with law enforcement as the search continues for Suzanne, police said.

He is locked up at the Bexar County jail Friday on a $2 million bond after being his arrest in Kendall County Wednesday.
