A North Austin mortuary employee is facing felony charges after allegedly experimenting on corpses and fraudulently obtaining death certificates.

Adeline Ngan-Binh Bui, 50, was charged with one count of state-jail felony abuse of a corpse and five counts of second-degree felony tampering with governmental records with intent to defraud or harm.

According to court documents obtained by FOX 7 these incidents go back to at least August 2022.

A former embalmer at Capital Mortuary Services has alleged to TFSC that Bui had "fraudulently initiated and obtained" at least ten death certificates under his name and license number without consent.

He also has alleged that Bui was experimenting on "separated anatomical structures." He listed the arms of an unknown dead person. The "experiment," involved injecting formaldehyde into the arms and observing its effects over time on the severed limbs, according to the court documents.

A cease-and-desist letter was issued to the mortuary on April 10. The letter stated that the funeral home had "failed to meet building, health, and safety codes and would have to "immediately cease and desist all operations". 

The Austin Police Department received eight death certificates that were allegedly signed by the former embalmer via an electronic signature, says court paperwork.

The former embalmer says he was not employed as a funeral director with Capital Mortuary Services, and instead was employed as a crematory operator, driver and embalmer.

He says he never accessed the Texas Electronic Vital Events Registrar (or TxEVER) to obtain those eight death certificates.

Buie allegedly communicated with a former employee regarding a fraudulent certificate in December 2023 in which she included screenshots.

Bui allegedly wrote "let's us[e] this update to monitor our experiment," followed by photos of what police say were severed and detached arms in various stages of decomposition. 

TSFC investigators communicated with APD saying that Bui "then allowed the severed body parts to be placed in the crematory retort, where the body parts, in their dissected and disturbed state, would be cremated," according to paperwork.

"Our criminal justice system is based on the presumption of innocence and a careful, critical evaluation of the evidence, facts, and their sources," Bui's legal team said in a statement to FOX 7. "This case involves complexities that are not immediately apparent and should not be sensationalized. Our legal team remains fully committed to defending and advocating for our client, Adeline Bui, with the expectation of fairness and due process."

Capital Mortuary Services is now closed.

The lawyer for a Maryland school district and U.S. Supreme Court Justice Neil Gorsuch had a wild exchange this week about a children's book amid an ongoing case brought by parents who want to be able to opt their children out of reading LGBTQ storybooks in their public school.

Gorsuch was asking Alan Schoenfeld, the attorney representing Montgomery County Public Schools, about "Pride Puppy!" a 32-page book that tells the story of a family celebrating Pride Day when their dog gets lost in the parade and the effort to reunite the pup with his loved ones.  

The rhyming alphabet book, which was described as "affirming and inclusive" by its publisher, allows readers to spot items starting with each of the letters of the alphabet while offering "a joyful glimpse of a Pride parade and the vibrant community that celebrates this day each year."

The book was previously used in the district's pre-kindergarten curriculum.

"And they're being used in English language instruction at age 3?" Gorsuch asked. 

"'Pride Puppy!' was the book that was used for the pre-kindergarten curriculum. That's no longer in the curriculum," replied Schoenfeld. 

"That's the one where they're supposed to look for the leather and things - and bondage – things like that," Gorsuch responded. 

"It's not bondage. It's a woman in a leather..."

A "Sex worker?" asked Gorsuch. 

"No. That's not correct. No," replied Schoenfeld.

"Gosh, I read it...drag queen?" said Gorsuch. 

Schoenfeld said the leather is actually a woman in a leather jacket and that "one of the words is drag queen." 

The high court was hearing arguments in the case brought by religious parents who say young children can’t be expected to separate a teacher’s moral messages from their family’s beliefs. 

Eric Baxter, the attorney representing Maryland parents in Mahmoud v. Taylor, told the justices that the school district violated the First Amendment by denying opt-out requests for books that "contradict their religious beliefs," even while allowing exemptions for other religious objections – such as books depicting the Muslim Prophet Muhammad.

Baxter said teachers were required to use the materials in class after the district approved certain LGBTQ-themed curriculum books in 2022. 

"When the books were first introduced in August of 2022, the board suggested they be used five times before the end of the year," he said. "One of the schools, Sherwood School, in June for Pride Month said that they were going to read one book each day."

The district initially allowed parents to opt out their children for religious concerns but reversed course by March 2023, citing concerns about absenteeism and administrative burdens.

Among the other storybooks at the center of the case is "Prince & Knight," a modern fairy tale aimed at children ages 4 to 8, which tells the story of two men who fall in love after joining forces to defeat a dragon and later marry. 

Another book frequently referenced during oral arguments was "Uncle Bobby's Wedding," which follows a young girl processing her favorite uncle’s decision to marry another man.

The Supreme Court is expected to issue a ruling in the case by late June.
