A British court has heard chilling details surrounding the death of a 25-year-old woman who allegedly jumped from a third-floor balcony after becoming trapped inside a flat with an armed teenager accused of threatening to torture her.

Tia Langdon suffered fatal injuries after falling approximately 35 feet from a balcony at an apartment building in Southampton, England, in August 2025. Prosecutors argue that her actions were driven by overwhelming fear after a series of escalating threats inside the property.

According to evidence presented at Winchester Crown Court, 18-year-old Jaiden Hassan-Agard entered the flat where Langdon and her friend, Shannon McNeil, were staying during the early hours of August 28. What began as an ordinary gathering allegedly turned into a terrifying ordeal.

The court heard that tensions rose after Hassan-Agard demanded that the two women help him package drugs. Prosecutors claim he became increasingly aggressive and accused them of stealing £250.

Armed with two machetes, Hassan-Agard allegedly threatened both women and spoke about subjecting them to torture. Jurors were told he referenced “waterboarding” and other forms of abuse while becoming increasingly hostile.

The situation reportedly became so frightening that Langdon was left in a state of extreme panic. Prosecutors said she was punched in the face and became visibly distressed. Witness testimony described her cowering in a corner of the room, trembling with fear and even losing control of her bladder.

“She was in a hysterical state,” the court was told.

As the threats continued, Langdon repeatedly moved between the living room and the balcony, apparently searching for a way to escape. Prosecutors argued that she felt trapped inside the apartment and believed there was no safe route through the front door.

The court heard that after another confrontation involving threats toward McNeil and her dog, Langdon made one final attempt to flee. She is believed to have either climbed or pushed herself over the balcony railing before plunging to the ground below.

Emergency services rushed to the scene, but despite medical efforts, she died from her injuries the following day.

Prosecutors maintain that although nobody witnessed the exact moment she went over the edge, the circumstances leading up to the fall paint a clear picture of a young woman driven to desperate measures.

“How frightened do you have to be?” prosecutor Sarah Jones KC asked jurors. “How trapped do you have to feel before deciding that climbing over a balcony is your best option?”

The court also heard allegations that Hassan-Agard continued threatening McNeil after Langdon’s fall. Prosecutors claim he prevented her from leaving immediately and used a machete to intimidate her before they eventually left the scene.

Witnesses allegedly saw the teenager walking away from the area while urging another person to hurry. Jurors were told that he and McNeil later changed clothes before separating.

Afterward, McNeil reportedly returned home and contacted police.

Investigators also presented evidence suggesting Hassan-Agard monitored news reports about Langdon’s death and exchanged messages on Telegram that appeared to reference fleeing from a possible murder investigation.

Hassan-Agard, who is now 19, denies all charges. These include manslaughter, assault causing actual bodily harm, making threats to kill, false imprisonment, and multiple offenses involving the use of a machete. He also denies allegations relating to the detention and intimidation of McNeil.

The trial remains ongoing, and jurors will ultimately decide whether the alleged threats and confinement inside the flat were responsible for creating the circumstances that led to Langdon’s fatal fall.
