This is the first picture of a mistress who was found dead at her home after a mystery ‘altercation’ with her married lover – who she stabbed to death before killing herself, an inquest heard.
Jessena Sheridan, 46, was one of two secret lovers of businessman Gary Williams, 58, from Swansea, South Wales.
Mr Williams, who was leading a triple life with three different women, was a devoted husband, father and grandfather with two other women on the go.
On Christmas Eve last year, the caravan dealer told his wife Elaine he was away on business, intending to spend the night with Miss Sheridan.
The inquest heard there was a mystery ‘altercation’ between the pair and they were both found dead in Miss Sheridan’s home, in Llanelli. A post-mortem examination found Mr Williams had been stabbed more than 50 times.
Mr Williams had been married to Elaine for almost 40 years but was having an affair with another woman since 1991.
He started a third relationship with Ms Sheridan in 2014 and neither women knew of each other’s existence.

Coroner’s officer Malcolm Thompson told the hearing: ‘Unbeknown to his family, it would appear that Gary had been leading a triple life.
‘Since 1991, Gary had been involved in an affair with a woman and would spend several nights a week with her.
‘He had informed her he was separated from his wife and had a son living abroad. She regarded themselves as partners.
‘He was also having an affair with Jessena Sheridan and attended her home on December 24 last year after leaving his family home.’
The inquest heard Mr Williams had spent the morning of Christmas Eve looking after his two grandchildren at the couple’s home in Swansea, South Wales.
He told his wife he had to deliver a caravan to Yorkshire and would be back on Christmas morning. His family never saw him alive again.
Miss Sheridan’s family received a text from her on Christmas Day and raised the alarm when they failed to hear from her again.
Evidence read at her inquest said that two of Miss Sheridan’s children entered the home in Llanelli on December 29 and went upstairs to find a large piece of cardboard blocking the stairway.

On it was written: ‘Kids do not come, call police instead. Don’t want you to see this. So sorry I lost it I’m ill.’
Upon entering an upstairs room, they found father-of-one Mr Williams naked with multiple stab wounds to the neck and chest along with arm injuries where he had tried to fend his lover off.
Mr Thompson said: ‘The walls and floor were heavily bloodstained. Several knives of various sizes were found on the bedroom floor.
A post-mortem examination found Mr Williams had been stabbed more than 50 times. He suffered injuries to his neck, chest and abdomen. He also had defensive injuries to his wrist.
Miss Sheridan’s body was found nearby with fatal knife wounds to the wrists and arms.
Carmarthenshire Coroner Paul Bennett said: ‘There are no clear details of what took place other than there must have been some sort of altercation between Gary and Miss Sheridan.
Police officers were called to the property in Llanelli at just after 8.30pm on Sunday, December 29, 2019. The court later heard that Miss Sheridan had died from self-inflicted knife wounds combined with an overdose
‘The tragedy is not knowing what it was that led to this terrible series of events and what the intention of Mr Williams’s assailant at the time.’
The court later heard that Miss Sheridan had died from self-inflicted knife wounds combined with an overdose.
She had suffered for much of her life from mental health problems, which were exacerbated by the death of her 13-year-old son, Wayne, in a bicycle accident in 2004.
Miss Sheridan had sought help in September last year, fearing her relationship with Mr Williams was ending.
The inquest also heard that Mr Williams, who had met his wife at 18 and married soon after, would often be away overnight travelling to motor auctions around the country as he had previously owned a car sales business.
Acting Senior Coroner Paul Bennett recorded a verdict of unlawful killing for Mr Williams and a narrative conclusion that Miss Sheridan had taken her own life.
‘I have found this to be a particularly difficult and tragic case of which to hear evidence,’ he said.
‘It is not disputed Gary Williams had been living a triple and somewhat complicated life. Not only was Mr Williams married but he also had a partner and was also having an affair with Jessena Sheridan whom he had met and formed a relationship with in 2014.
‘This relationship had been secretly kept from both Gary’s wife and his partner. This triple existence was managed for many years by Gary as continued his working and social life.
‘He had been able to separate these relationships entirely without either his wife or long-term partner having any knowledge of his further involvement with Miss Sheridan.
‘The reality is that he left to visit Miss Sheridan at her home that same day. No clear details are available of what actually took place thereafter other than there must have been some sort of altercation between Gary and Miss Sheridan.
‘The real tragedy of this case is not knowing what it was that led to this terrible series of events and what the intention of Mr Williams’s assailant at the time.’
Mr Bennett said Miss Sheridan was a ‘troubled individual who had experienced many traumatic and tragic events in her life’.
A separate inquest on Miss Sheridan was held three hours later to keep the two families of the deceased businessman and his lover apart.
A statement from Miss Sheridan’s children was also read aloud at the hearing.
It said: ‘Mum was an incredibly strong woman. She would treat her children to excellent restaurants and loved exploring the coast with them to find the best beaches.
‘She had a passion for cooking and created her own signature dishes and relished her family enjoying her dishes.
Her family recalls that Jessena, who had part-Welsh part-Mauritian heritage, often said: ‘My heart is in Wales but my soul is in Mauritius’.
