A 17-year-old student at a "therapeutic boarding school" in Utah died of sepsis after school staff ignored her health complaints, according to recent autopsy results and a lawsuit filed on behalf of the deceased student and her family.

Taylor Goodridge died of peritonitis, an infection of abdomen tissue, followed by sepsis, which caused her organs to fail, in December 2022 at Diamond Ranch Academy in Utah.

"It's something that's easily treated with antibiotics, especially with a healthy 17-year-old," attorney Alan W. Mortensen of Mortensen and Miline told Fox News Digital. "The first signs of peritonitis are vomiting and stomach cramps, both of which Taylor had for… at least two-and-a-half weeks before she died. She was never taken to the hospital. Her complaints were ignored, and she was punished for making the complaints."

The infection eventually spread to her heart, liver, kidney and pancreas, said Mortensen, citing the Utah Medical Examiner's autopsy results.

Goodridge was allowed to call her parents once a week at the school that touts itself as a "world-class residential treatment center and therapeutic boarding school," but school staff allegedly blocked her access to the phone when she was sick.

Utah Department of Health and Human Services records obtained by Mortensen show Goodridge vomited at least 14 times prior to her death, including seven times within an 11-hour time frame.

Staff at the school, which has a $12,000 monthly tuition per student, allegedly told Goodridge "that she was faking it and needed to ‘suck it up.'" When the 17-year-old student was experiencing "excruciating pain," school employees told her to "drink water and take aspirin," the lawsuit states.

On the day of her death, staff allegedly forced Goodridge to get out of bed, take a shower, and go to the school's medical clinic, where her family's attorneys believe she died.

"We are devastated to learn that Taylor’s death was entirely preventable had Diamond Ranch Academy cared," the girl's parents, Dean Goodridge and AmberLynn Wigtion, said in a recent statement. "We are also dumbfounded that the State of Utah’s Department of Health and Human Services has not held Diamond Ranch Academy accountable for Taylor’s death, settling with Diamond Ranch Academy without any input from our family."

They continued: "We intend to continue to pursue all avenues to hold Diamond Ranch Academy accountable for her death to make sure this does not happen to other innocent teens and their families."

Mortensen mentioned three other separate incidents involving alleged abuse at the school, which could not be reached for comment.

"This place should be out of business, and the fact that the state of Utah allowed them to go back into business is beyond," the attorney said, adding that he would "never send" his own child to the school.

Celebrities such as Michael Jackson's daughter, Paris Jackson, who attended Diamond Ranch Academy, and Paris Hilton, who attended Provo Canyon School in Utah, where she said she was sexually abused, have also called for the school to be shut down, according to Elle magazine.

"It is vital that facilities like Diamond Ranch Academy are held accountable," Hilton said in a December 2022 tweet after Goodridge's death.

Russia reportedly has deployed a new battle tank in Ukraine that the United Kingdom Ministry of Defense suggests commanders will be "unlikely to trust" in combat. 

The T-14 Armata, which has an unmanned turret and is operated by a crew remotely controlling its armaments from "an isolated armored capsule located in the front of the hull," has started firing at Ukrainian positions, Reuters reported, citing the Russian state-run RIA Novosti news agency. 

State media said the new tanks have "not yet participated in direct assault operations," but have undergone "combat coordination" at training grounds within Ukraine and are being defended with extra protection on their flanks, Reuters added. 

However, the U.K. Ministry of Defense says rolling out the new tanks is "likely to be a high-risk decision for Russia."

"Eleven years in development, the program has been dogged with delays, reduction in planned fleet size, and reports of manufacturing problems," it said in a series of tweets in late January. 

"An additional challenge for Russia is adjusting its logistics chain to handle T-14 because it is larger and heavier than other Russian tanks," it tweeted. 

"If Russia deploys T-14, it will likely primarily be for propaganda purposes," it added. "Production is probably only in the low tens, while commanders are unlikely to trust the vehicle in combat." 

Moscow first ordered production of 2,300 of the tanks by 2020, but that goal has since been pushed back to 2025, Reuters reported, citing Russian media.

In December 2021, the Interfax news agency said the Russian state-owned conglomerate Rostec had started working on building around 40 of the tanks with an expected delivery after 2023, according to Reuters. 

The T-14 reportedly can reach a max speed of 50 mph. 

News of the deployment Tuesday came as Putin ally and former Russian President Dmitry Medvedev said in Moscow that "the world is sick and quite probably is on the verge of a new world war." 

Medvedev, who is currently the deputy chairman of the Security Council of the Russian Federation, added that concerns about a nuclear conflict are more serious than worries about climate change, according to Reuters. 

"If the United States continues to follow its current course of confrontation with Russia, with the stakes constantly escalating on the verge of sliding into direct armed conflict, then the fate of START [nuclear arms treaty] may be a foregone conclusion," Vladimir Yermakov, who leads the Russian Foreign Ministry’s Non-Proliferation and Arms Control Department, also was quoted by the news agency as saying Tuesday.
