A woman died in a Twickenham house boat after an early hours argument with her boyfriend.

Lori Waterworth, who lived in Ducks Walk, was found hanged on July 31, 2014 after battling with depression, West London Coroner's Court heard on November 27.

The 24-year-old, who was unemployed at the time of her death, was on anti-depressants and struggled with anger-management issues, the court heard.

Chris Sheppey, Miss Waterworth's boyfriend of two-and-a-half years, said: "I was aware they put her on something but I thought it was to help her sleep.

"She was OK, she would have her down days but then she would bounce back - she would be down because she knew what she had done was bad, but I never held it against her."

He said the couple had argued the night before their lodger found her dead.

Mr Sheppey added: "I don't even know how to describe it, I have never seen a person like that - it was just not Lori, it was like she was possessed.

"The last time we spoke was 4am when I left because I couldn't see the situation getting any better.

"I thought the best thing to do was to leave and it would calm down because she was in a dark place."

Miss Waterworth, who was born in Halifax, moved to Twickenham to be with her partner.

She had worked at a care home and as a restaurant manageress.

Her mother, Julie Waterworth, broke down in tears while giving evidence at her daughter's inquest.

She said: "I knew she had been depressed but I didn't know until she passed that she was on anti-depressants.

"She just shouted and screamed a lot when she got angry - it was nothing out of the ordinary."

She added that she was on holiday when Miss Waterworth was found dead and that the family was "surprised" by the news.

Miss Waterworth was recommended for anger-management and psychiatric care, the court heard.

A toxicology report found she had taken cannabis and "been affected" by alcohol at the time of her death, as well as non-prescribed antidepressants.

Coroner Chinyere Inyama recorded an open verdict as he could not be satisfied whether or not Miss Waterworth was hoping to be found alive.

The case took more than one year to be heard at coroner's court and Mr Inyama apologised to Miss Waterworth's family.

He said: "I can't go into detail but it shouldn't have [taken more than a year] and I apologise for that.

"It is poor case management."
