The husband of a Texas woman who has been missing since attending a party in October has been charged with her murder.

On Thursday, November 7, Brad Simpson, 53, was “charged with murder in connection with the death of his wife,” Suzanne Clark Simpson, 51, a spokesperson for the Texas Department of Public Safety, confirmed to PEOPLE.

The mother and real estate agent, who resides in Olmos Park, Texas, has been missing since Monday, October 7. She and her husband reportedly attended a party at The Argyle private club in San Antonio on October 6.

According to KSATcourt records show Simpson’s bail for the murder charge was set at $2 million. The outlet said that in addition to previous charges including assault causing bodily injury to a family member and unlawful restraint, his total bail is set at $5 million.

By WJARSimpson left the Bexar County Jail around 1:15 p.m. local time on Thursday before returning and being charged two hours later.

The arrest affidavit was sealed for 30 days, the outlet reported, citing the county clerk.

The television station added that even if the body has not been found, investigators believe they have “sufficient evidence to proceed anyway.”

Simpson’s brother, Barton, said in a statement to KSAT on Thursday: “It’s heartbreaking, but it brings some peace to our family to know that authorities have gathered enough evidence to be able to confidently pursue charges .”

“It also helps us come to terms with the fact that Suzanne is no longer with us, allowing us to begin a difficult grieving process and focus on rebuilding our lives, especially for the sake of the children and our extended family. We remain grateful to all law enforcement involved for their professionalism in handling this situation,” Barton added, according to the outlet.

The charges come nearly a month after Olmos Park Police Chief Fidel Villegas said during an Oct. 9 news conference broadcast by KENS that Simpson was arrested after failing to show up for a meeting with police. PEOPLE previously reported that he was arrested and charged with assault and domestic violence.

Villegas said at the time that after learning of Suzanne’s disappearance, police were informed of an altercation at the family home that may have turned physical before she was reported missing.

According to Villegas, Simpson and Suzanne had been married for approximately 22 years. NBC News reported her as a mother of four children.

PEOPLE also reached out to the Olmos Police Department for additional information, but did not immediately receive a response. It is not immediately clear whether Simson has pleaded guilty.
