The business partner of the husband of the missing Suzanne Simpson was arrested and indicted after incriminating texts were discovered.

This week, Brad Simpson, the husband of the missing Texas realtor Suzanne Simpson, was formally charged with killing the 51-year-old mom of four, while his longtime business partner also remained behind bars, accused of the same crime.

On Monday, James "Val" Cotter was indicted by a grand jury in Bexar County, Texas, for tampering with evidence with the intent to impede an investigation and for possessing illegal weapons, according to jail records.

Brad Simpson's longtime friend and business partner, Cotter, is accused of concealing Simpson's gun following a series of ominous texts exchanged on Oct. 8, two days after his wife disappeared and before Simpson's arrest on Oct. 9.

"Can you meet me at your house in Bandera?" Simpson allegedly texted, according to an affidavit. "I'm short on time."

Cotter replied, "I'll arrive in 40 minutes." Simpson responded, "Alright, ensure you leave all that crap in the pump house, particularly the gun."

"I'm sorry for the urgency, but you're my only hope right now...social media is tearing me apart," Simpson reportedly said.

The same day, Cotter texted Simpson, "Come over now! I won't reveal it," followed by the message, "You're my sibling."

Authorities claimed that Cotter concealed Simpson's AK-47 in the wall of his home, despite it being unregistered and modified into a "machine gun," according to police.

On Oct. 21, Cotter was arrested and charged with third-degree felonies for tampering with evidence and possessing a prohibited weapon. He was released from custody last month after his bond was reduced from $1 million to $100,000, according to a local outlet.

According to the bond conditions, he is not allowed to communicate with Brad Simpson or possess a firearm, and he has been equipped with a GPS tracker.

The investigation of Suzanne Simpson's disappearance is connected to his case, as authorities have stated.

On Oct. 6, Suzanne disappeared after an alleged argument with her husband of 22 years in front of their house in Olmos Park, in the San Antonio area. Despite not finding her body, authorities believe that Simpson intentionally caused her death on or about that day, as stated in the indictments.

According to an affidavit, a neighbor reportedly saw Simpson assault his wife the night of her disappearance and heard screams coming from the woods nearby. Meanwhile, the couple's 5-year-old child told a school counselor that on the evening of Oct. 6, her father allegedly pushed her mother against the wall, hit her mother on the face, and hurt her mother's elbow inside their residence, as well as turned off her mother's phone because they were fighting.

On Nov. 7, Brad was charged with Suzanne's murder.

On December 3rd, a Bexar County grand jury charged Simpson with two first-degree felony offenses: murder and aggravated assault with a deadly weapon that caused serious bodily injury to a family member. These charges carry a maximum sentence of life imprisonment. Additionally, Simpson was indicted for tampering with a corpse, two counts of tampering with physical evidence, and possession of a prohibited weapon.

According to indictment records and KABB reporting, law enforcement accuse Simpson of hiding Suzanne's DNA on a "reciprocating saw."

On Oct. 8, two days after his wife disappeared, Simpson concealed a reciprocating saw during a missing persons investigation, according to the indictment.

The indictments accuse Simpson of committing a murder on Oct. 7 and subsequently altering, destroying, and concealing the corpse with the intention of impeding the investigation.

Since October 6th, there have been no indications that Suzanne is still alive, as confirmed by her cellphone records, financial records, family, friends, and co-workers, according to authorities.
