A drug dealer has been jailed after being convicted of manslaughter following the death of a woman who fell from a third-floor balcony while attempting to escape threats and violence.

Jaiden Hassan-Agard, 20, of Southampton, has been jailed for 18 years at Winchester Crown Court today (23 October), after being found guilty following a trial.

On 28 August 2025, Tia Langdon, 25, was at a flat in Cuckmere Lane, Southampton, when Hassan-Agard became enraged after accusing her and another woman of stealing drugs from him.

Armed with two machetes, he subjected both women to a prolonged period of intimidation, threats and violence.

During the incident, Hassan-Agard threatened to harm the women and assaulted Ms Langdon, breaking her nose.

The Crown Prosecution Service proved that his actions left Tia feeling frightened, trapped and desperate to get away.

Faced with the situation he had created, she attempted to escape from the flat via the balcony and fell to the ground below. She sadly died in hospital the following day.

Hassan-Agard was convicted on 14 July 2026 of manslaughter, two counts of false imprisonment, two counts of threats to kill, assault occasioning actual bodily harm, two counts of threats with an offensive weapon in private, and kidnapping.

James Foster, Specialist Prosecutor, of the Crown Prosecution Service, said: "Tia Langdon lost her life because of the fear, violence and intimidation caused by Jaiden Hassan-Agard’s actions.

"He subjected Tia and another woman to threats and erratic behaviour, creating a situation which left her feeling as if she had no safe means of escape.

"While nobody witnessed the precise moment she fell, prosecutors proved that Hassan-Agard's conduct was a significant cause of the events which led to her death.

"He then compounded the suffering of those involved by refusing to seek emergency help and continuing to threaten and control the other victim in the aftermath.

"Today’s sentence reflects the gravity of Hassan-Agard’s crimes. I recognise that no sentence can ease the profound pain and loss experienced by Tia’s family, or undo the harm suffered by the other victim in this case. 

"I hope, however, that they can take some comfort from knowing that Hassan-Agard has been held accountable for his actions."
