SAN ANTONIO – A newly unsealed affidavit reveals more information about the hours leading up to the disappearance of Olmos Park mother Suzanne Simpson and her husband’s movements the next day.

Brad Simpson is now accused of murdering his wife, but her body has not been found.

SUNDAY, OCTOBER 6

Evening

Suzanne Simpson and Brad Simpson attend a party at the Argyle Club in Alamo Heights. They also had their 5-year-old daughter with them.

Witnesses say Brad and Suzanna got into a “verbal argument” at the party and Suzanne left with their daughter around 8:30 p.m.

Between 20:40 – 20:51

HEB’s video surveillance shows Suzanne and her young daughter visiting the store. Authorities believe they then went home.

21:15 – 21:25

Suzanne calls a friend to say she’s coming. His car is seen on security camera footage arriving at his friend’s house at 9.25pm.

During the trip, Suzanne called her mother to tell her that Brad had attacked her, causing pain in her arm, back and neck.

Investigators learned from Suzanne’s cell phone carrier that her service was suspended around the same time at the subscriber’s request. They believe Brad Simpson called to do this.

This contradicts Brad’s original story that Suzanne lost her phone at HEB.

22:22

Suzanne’s family member later provided authorities with a screenshot showing the Find My Friends location was at their home.

This is the last known location of the iPhone.

after 22:22

A neighbor told police she saw Brad and Suzanne “arguing loudly” and a “physical struggle” in her front yard.

After that, the neighbor said, Suzanne broke free and ran into a wooded area, and Brad followed her. Then he heard screams.

About an hour later, the neighbor said he heard Brad’s truck starting and returning an hour later.

23:09

Investigators say Brad “intentionally engaged in on/off cycles” to turn his phone off completely. This prevents it from collecting data. It’s called a lockdown, and officials say it’s rare. They describe it as something someone would do to “avoid detection.”

MONDAY, OCTOBER 7

7:53 am

Brad Simpson drops his daughter off at Howard Early Childhood Center. Surveillance video shows Brad finding at least two white trash bags with red string and what appeared to be a large ice chest in the truck bed area.

9:12 am

Authorities say Brad Simpson walked through a Whataburger in Boerne and bought food with a debit card.

Surveillance cameras also provided a clearer view of what was in the back of his truck: Three white garbage bags, a large, gray, heavy-duty trash can, an ice bin, a bulky item wrapped and secured in a silver-coated blue tarp. Colored metal firewood rack placed over blue tarpaulin to hide the tarpaulin and reduce its weight.

By observing the blue tarp further, your Affiant believes that due to its shape and size, an unknown object is hidden inside the blue tarp and is secured with a strap/rope. Given Your Associate’s training, experience, and past investigations, Your Associate is aware that criminals will often conceal, transport, or conceal their victims in the manner described above in order to avoid detection by law enforcement.

9:53 am

Simpson arrives at The Home Depot on Bandera Road in Boerne.

Authorities say the video shows him using cash to purchase two bags of Quikrete cement, an orange Home Depot construction bucket with a lid, a box containing 32 heavy-duty garbage bags, a 30-ounce bottle of Clorox disinfectant spray and insect repellent.

Authorities also learned that Simpson approached a stranger in the parking lot and asked where the nearest dumpster was.

The person referred him to Kendall County Solid Waste.

Brad Simpson then “intentionally turned off his cellular device,” the affidavit states. He continued to turn his phone on and off.

Between 9:53 and 11:15

Vehicle location data shows Brad’s truck was near the Kendall County Solid Waste Oversight Agency, and there is video from a nearby business that captures Simpson’s truck driving away from the landfill.

11:15

Simpson arrives at a gas station in Boerne. In the video, he can be seen filling up with gas using his debit card, then using the money to buy water jugs.

Upon further review of the surveillance video, the white trash bags from his (Simpson’s) truck bed were now found to be missing, but the blue tarp, firewood rack, and trash can were still present.

The affidavit also states that Brad changed his shoes from black sandals to dark-colored cowboy-style boots.

after 11:15

A video investigation team found surveillance video showing Brad’s truck driving west from Boerne toward Bandera. The blue awning with the fire rack on top remains inside the truck bed.

Location data recorded Brad’s truck traveling west through Bandera County toward Medina, Texas.

The on/off cycle of the mobile phone continued.

His vehicle remained in the Medina area for approximately 13 minutes before heading east toward Kendall County.

13:41

Brad’s truck is seen on camera entering the Boerne area.

“After observing that the blue tarp was no longer visible and the firewood rack was now repositioned inside the truck bed,” the affidavit reads.

15:27

Brad Simpson returns to Howard Early Childhood Center to pick up his daughter.

The blue tarp and metal firewood rack on the bed of the truck were missing. The ice chest and large, gray, heavy-duty trash can remained.

16:07

Authorities say Brad showed up at the Bubble Bath Car Wash in San Pedro. Security cameras show him washing and cleaning the driver’s front side and the rear left passenger side of the passenger compartment.

Later photos show dried cement splatters in the rear passenger compartment of the vehicle, which were incorporated into the truck bed. Another photo showed a 30-ounce bottle of Clorox in the rear passenger compartment of the vehicle. The truck bed contained only the ice chest and no other items observed in previous surveillance video, the affidavit states.

16:35

Simson texted James ‘Val’ Cotter:

“If you’re in Bandera can you get off your ass and meet me at your house?” and “I don’t have much time…”

Cotter replied, “I’ll be there in 40 minutes.”

Simpson said, “Okay, be sure and leave all this nonsense, especially the gun, at the pump house.”

20:31

Cotter texted Simpson: “Come here! I won’t tell anyone.”

TUESDAY, OCTOBER 8

A Bandera County Sheriff’s Deputy contacted Simpson, who was standing near an active fire at a property in that area.

Three cell phones and a laptop were found in that burn pit. Authorities believe all three phones belong to Brad.

Your subordinate’s training and experience have taught him that criminals often attempt to destroy evidence in order to disrupt or hinder a criminal investigation.

WEDNESDAY, OCTOBER 9

Authorities arrested Brad Simpson and said he “did not appear surprised” or questioned why he was being arrested. He told the police that Suzanne lost her phone at HEB on Sunday. Authorities say he was not concerned about his wife’s disappearance.

OTHER INFORMATION

Brad Simpson had a cell phone on him when he was arrested. Authorities found two notes titled “This next life” and “Last will and testament.”

In the notes, Simpson apologizes for physically assaulting Suzanne Simpson, once in August 2023 and a second time on 10/06/2024. Authorities say these notes were created on 10/08/2024.

Blood was found in Simpson’s truck, but authorities write in the affidavit that it belonged to Brad.

The affidavit states Suzanne told her banker that Brad often took her phone away but to tell her children that she had lost it. Suzanne also told the banker “if he gets lost to look for her in the lake.”
