A mum warned her children not to enter the bedroom after she murdered her cheating lover before taking her own life.
Jessena Sheridan was found dead next to the body of lover Gary Williams at her Welsh home just days after Christmas last year.
The 46-year-old, from Llanelli, discovered that her victim had a wife and was in another long-term relationship with a third woman.
An inquest at Pembrokeshire and Carmarthenshire Coroner’s Court heard that Sheridan had left a note on her bedroom door after the bloodbath.
She wrote: “Kids do not come, call police instead. Don’t want you to see this. So sorry. I lost it I’m ill”.
Gary Williams ran a business selling caravans and left his Swansea home after telling his wife he was away to deliver a caravan but would return the following morning.
But the father-of-one instead travelled to Sheridan’s home where his body was later discovered saturated in blood, Wales Online reports.
The inquest 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.
Coroner’s officer Malcolm Thompson told the inquest in Llanelli that Mr Williams had spent the morning of Christmas Eve looking after his two grandchildren.
He left home that afternoon to deliver the caravan, saying he would be back for Christmas morning.
Mr Thompson said: “This was the last time he was seen by his family. 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 from the Llanelli area with whom he would spend several nights during the week.
“He had informed her that he was separated from his wife and he had a son living abroad. “She regarded themselves as partners.
“Unbeknown to either his wife or his partner Gary, was also having an affair with Jessena Sheridan.
“It is believed Gary attended at her home on December 24 after leaving his family home.”
A forensic tent remained outside the property in Lakefield Place, Llanelli, on December 31.
The court heard that the last contact Miss Sheridan’s family had with her was a text message on the afternoon of Christmas Day.
On the evening of December 29, members of her family went to her home in Lakefield Place, Llanelli, having become concerned for her welfare.

The naked, bloodstained body of Mr Williams was found in a bedroom near that of Miss Sheridan, who had lacerations to her wrists and arms.
“The walls, the floor were heavily bloodstained and several knives of various sizes were on the bedroom floor,” Mr Thompson said.
A post-mortem examination found that 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.
In the months leading up to Miss Sheridan’s death, the inquest was told that she had been admitted to a mental health unit following concerns for her welfare.
The hearing was told following the death of her 13-year-old son, Wayne, in 2004 in a bicycle accident, Miss Sheridan was “devastated and overwhelmed with intense grief”.
Upon admission to A&E at Glangwili Hospital on September 9, 2019, she told members of the crisis team “about the death of her beloved teenage son” and made reference to fears that her current relationship “was about to end”.
Acting Senior Coroner Paul Bennett said “there was no doubt” Miss Sheridan was “a troubled individual who had experienced many traumatic and tragic things in her life”.
“She had a number of referrals to mental health services as a young person and an adult.”
The two deaths, which were held as separate inquests, were described by Mr Bennett as a “particularly difficult and tragic case of which to hear evidence.”
He added: “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’ assailant at the time.”
For Mr Williams, a conclusion of unlawful killing was recorded by the coroner.
The conclusion for Miss Sheridan’s death was given as a narrative conclusion – which mentioned “sharp force injury to the left wrist and elbow and multi-drug toxicity”.
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”.
