“I’ll never forget and it’ll never leave my mind, the look on that doctor’s face as he was reading through the files,” Dorsett, 53, said. “… He was just shaking his head, like: ‘what in the living hell is going on?’”

His mother, 70-year-old Dorothy Dorsett, was in recovery after a surgeon removed a tumor from her digestive tract. But she was hardly eating and had an abnormally fast heartbeat, according to a lawsuit Dorsett later filed. She was moved to the ICU nearly a week after the surgery.

“She just started really spiraling, pain,” Dorsett said. “She was not my mom.”

She died days later, on Aug. 4, 2023.

About a year later, another patient, William Bryan, 70, died after the same surgeon operated on him.

The surgeon, Thomas Shaknovsky was arrested this week, accused of accidentally removing Bryan’s liver instead of his spleen, prosecutors said. Shaknovsky operated on both Dorothy Dorsett and Bryan at Ascension Sacred Heart Emerald Coast in Miramar Beach.

Shaknovsky and his lawyer could not be immediately reached for comment. However, he has denied wrongdoing in Dorothy Dorsett’s case in court filings of his own, arguing that some of the allegations were inaccurate and that descriptions of Dorsett’s care were incomplete. The lawsuit remains ongoing.

The hospital did not immediately return a request for comment. Earlier this week, Macdonald Walker, a spokesperson for Ascension Sacred Heart, said in a statement that Shaknovsky “was never a Sacred Heart Emerald Coast employee and has not practiced at any of our facilities since August 2024.”

Weyman Dorsett filed a lawsuit against Shaknovsky and Ascension Sacred Heart last year, accusing the doctor and hospital of negligence. He spoke out for the first time since his mother died in an interview with NBC News on Thursday.

“I’ve got two boys, a wife, now a grandbaby, and you know, I’m trying to be there for them, but, man, I’ve struggled mentally in dealing with it,” he said. “It’s just not right.”

On July 24, 2023, Dorothy Dorsett was admitted to the hospital after suffering abdominal pain, Weyman Dorsett, said. At the time, he said his mom was “in great health.”

“She was going non-stop. She lived on her own, drove everywhere, she went all over,” he said. “Prior to the surgery, she flew to my oldest son’s wedding in Bentonville, Arkansas, with a broken leg from a car wreck.”

At the hospital, his mom was diagnosed with gastrointestinal bleeding and acute blood loss anemia, according to the civil complaint.

The next day, the Dorsett family met Shaknovsky, whom Weyman Dorsett described as “odd.” He said the doctor prayed by his mom’s bedside before the surgery.

“It was way over the top,” Weyman Dorsett said. “It was very insincere to me.”

He said his mother thought Shaknovsky was “very weird.”

That day, Shaknovsky performed a colonoscopy and found a tumor in Dorothy Dorsett’s digestive tract, which he removed on July 27, 2023, according to the complaint.

During the surgery following the colonoscopy, Shaknovsky did not perform a routine test, which would have ensured there were no leaks in a newly joined intestine, according to the complaint.

Shaknovsky told the family that the surgery “went great,” Weyman Dorsett said, but his mother’s condition immediately started to deteriorate.

He said that his mom was moved to the ICU on Aug. 2, 2023.

Weyman Dorsett left that night, but his mother called him to come back to the hospital at midnight, saying she was going to die.

“My mom looked at me and just said, ‘It is what it is. I’ve lived a good life,’” he said. “And I had to sit there and watch her die.”

On Aug. 3, 2023, a doctor on call, Dr. Chun W. Chen, documented Dorothy Dorsett’s condition, according to the complaint, noting that he saw “more air than I would expect postsurgical” and mentioning concern “for bowel perforation specifically around the chain sutures in the pelvis.”

Chen added in the report that pockets of air had formed around Dorothy’s pelvis, according to the complaint.

“Although this may be postsurgical, cannot exclude bowel perforation,” he wrote.

Chen said in a brief phone call that he didn’t remember the patient and declined to comment further.

That evening, Shaknovsky documented in a daily progress note the air and fluid collection in Dorothy’s pelvis, according to the complaint.

Shaknovsky did not advise surgical intervention due to Dorothy’s declining organ function and risks associated with anesthesia, the complaint says.

Dorothy Dorsett was pronounced dead at 5:29 a.m. on August 4, 2023, according to the complaint. She passed away surrounded by family, the complaint says.

“Until you go through it yourself, and to be there with my mom and watch her suffer, and to be there when she takes her last breath has been devastating,” Weyman Dorsett said. “I suffer every day. It’s a haunting memory that I can’t erase out of my mind.”

Allegations of another botched surgery

On Aug. 21, 2024, prosecutors allege that Shaknovsky accidentally removed William Bryan’s liver instead of his spleen during what was scheduled to be a laparoscopic splenectomy.

Shaknovsky, who had been licensed to practice medicine in several states, had his Florida license suspended about a month after Bryan’s death. Later that year, he voluntarily surrendered his license to practice in Alabama. New York then suspended his license in 2025.

Bryan’s widow, Beverly Bryan, filed a civil lawsuit against Shaknovsky in 2025, accusing the surgeon of causing her husband’s death.

After the suit was filed, Weyman Dorsett learned that the Florida Agency for Health Care Administration completed an investigation into his mom’s death in September 2024, after Bryan’s botched surgery and more than a year after Dorothy’s death.

The investigation found that Shaknovsky and other hospital physicians “failed to appropriately use diagnostic testing and delayed in ordering imaging to timely treat sepsis” in Dorothy Dorsett’s case, according to a copy of the report.

The Florida Agency for Health Care Administration did not return a request for comment.

Shaknovsky was indicted by a grand jury on a charge of second-degree manslaughter in the death of Bryan, according to officials.

“It’s bittersweet,” Weyman Dorsett said. “You know, nothing’s going to bring back Mr. Bryan, or my mom and all the other people that are still out there that have been butchered and suffered.”

Dorothy Dorsett grew up in Birmingham, Alabama, where she and her husband, Weyman Dorsett II, her high school sweetheart, raised their two children: Weyman Dorsett III and his sister.

“She just was everything you would think the American dream mom would be,” he said. “She led by example, best cook in the world. She was our rock.”

She and her husband moved back and forth from Alabama to Miramar Beach, Florida, about 30 miles west of Panama City. She moved to Miramar Beach permanently following the death of Weyman Dorsett II in 2021.

Weyman Dorsett III described his mother’s passing as a “big piece missing.”
