Brad Simpson business partner arrested on felony weapons charges 2 weeks after Suzanne’s disappearance

SAN ANTONIO – A longtime business associate of Brad Simpson was arrested late Monday on felony weapons charges, two weeks after Simpson’s wife Suzanne Clark Simpson was reported missing.

James Valle Cotter, 65, faces felony charges of possession of prohibited weapons and tampering with evidence with the intent to impair an investigation, Bexar County Jail records show.

Cotter’s bond on the tampering with evidence charge had been set at $500,000 as of Tuesday afternoon, while bond on his second charge had yet to be set by a judge, a jail official confirmed to KSAT.

A law enforcement source told KSAT Tuesday Cotter is accused of helping Brad Simpson hide a weapon possibly tied to his wife’s disappearance case.

Cotter and Simpson, 53, have been partners in multiple real estate business ventures, background checks for the two men reveal.

A spokesman for the Texas Department of Public Safety, Cotter’s arresting agency, told KSAT Tuesday afternoon, “The Texas Rangers and the OPPD (Olmos Park Police Department) arrested Mr. James Valle Cotter at his home yesterday. During the Missing Person investigation in Olmos Park, investigators learned that Mr. Cotter had committed the offense of Tampering with Evidence, which is a 3rd Degree Felony. Mr. Cotter is a business associate of Mr. Brad Simpson, husband of Suzanne Simpson, who has been missing since 10-07-2024.”

The spokesman declined to release additional details from Cotter’s arrest.

Cotter’s arrest late Monday came more than two weeks after Brad Simpson reported his wife Suzanne missing. Law enforcement authorities have said Brad Simpson has been uncooperative.

He remains in the Bexar County Jail on bonds totaling $2 million and has a federal detainer due to a pending felony firearms charge.

Cotter, who remained at the Bexar County Jail as of Tuesday afternoon, will be prohibited from possessing guns and will be on full house arrest if he posts bond, court records show.

The search for Suzanne Clark Simpson is ongoing. The Olmos Park mother of four and realtor was last seen on Sunday, Oct. 6, and her husband has since been arrested on charges unrelated to her disappearance.

Here’s a timeline of events in this case:

Sunday, Oct. 6:

• The couple attended a party at The Argyle, a private dinner club on Patterson Avenue in Alamo Heights, before returning to their home, which they share with their two children. Olmos Park Police Chief Fidel Villegas said the couple fought at that event.

• A neighbor told police that between 10-11 p.m., he heard an argument outside his bedroom window that became louder and “seemed closer to his window.” When the neighbor looked out his window, he saw the Simpsons in a physical altercation, an arrest warrant affidavit stated. He said Suzanne Clark Simpson was trying to get away from Brad Simpson as he tried to pull her down. It appeared Brad Simpson “was clearly attempting to keep Ms. Simpson from running away,” the neighbor told authorities, according to the affidavit.

• The neighbor told authorities he last saw the couple heading westbound. The neighbor went outside to investigate, and a short time later, he heard two to three screams from a brushy area east of his home, the affidavit states.

• About an hour later, the neighbor saw Brad Simpson start his black GMC pickup truck and leave his house. The neighbor told authorities he saw Brad Simpson return one to two hours later. The neighbor did not call the police but told them the account he was questioned at a later date.

Monday, Oct. 7:

• The last activity on Suzanne Simpson’s phone was around 7:15 a.m., according to police. The coordinates showed the phone was in a business parking lot in Olmos Park.

• At 3 p.m. their child’s school called Brad Simpson and advised him that their child had not been picked up, the affidavit states.

• Around 10 p.m., Brad Simpson reported his wife missing.

Tuesday, Oct. 8:

• At some point, Brad Simpson became uncooperative with investigators and failed to show up for an interview. Police learned that he relocated to his ranch in Bandera County, the affidavit stated.

• Investigators questioned Brad Simpson’s brother, Barton Simpson, who told police that Brad Simpson had called him and apologized for all the problems he had caused, the affidavit stated.

• At 4:30 p.m., police interviewed staff at the school one of their children attends. The child told staff that her parents were “fighting” and that her dad assaulted her mom and took her phone away, the affidavit states. The child also said Suzanne Simpson had a bruise on her elbow.

• At 4 p.m., Villegas held another media briefing and released a photo from a security camera showing Suzanne Simpson outside The Argyle.

Wednesday, Oct. 16:

• The search at the landfill continued.

• The brother of Brad Simpson, Barton Simpson, condemned his brother on social media. He released the following statement on social media:

“Until Brad chooses to cooperate, we will continue cooperate for him, as we have from the very beginning of this heartbreaking ordeal. This is not how he was raised, and this is not who we are. Our parents instilled in us the values of honoring and protecting others, and they are truly remarkable people.

“The devastation this has caused to our family is overwhelming. Brad’s refusal to cooperate is unacceptable. My sister and brother-in-law have stepped up to take care of the children, but the impact on our parents has been shattering. Our lives have been irreparably changed.

“We will not rest until we find Suzanne.”
