A married businessman who lived three lives with three different women was found stabbed to death by one of his secret lovers, who then killed himself.
Gary Williams, 58, had been married to Elaine for many years but had a long-term relationship with another woman since 1991 and had a girlfriend, Jessena Sheridan, 46.
On Christmas Eve last year, the caravan dealer informed his wife Elaine that he was away on business to spend the night with Mrs. Sheridan.
The investigation revealed that there was a mysterious altercation between the two and both were found dead in Miss Sheridan's house.
Mr. Williams had been married to Elaine for nearly 40 years but had had an affair with another woman since 1991.
He began a third relationship with Ms. Sheridan in 2014 and neither woman knew of the other's existence.
Gary Williams, 58, of Swansea, South Wales, was a devoted husband, father, and grandfather who had two other wives en route.
Coroner Malcolm Thompson said of the hearing: “Unknown to his family, it appears that Gary lived three lives.
Gary had been involved in an affair with a woman since 1991 and spent several nights a week with her.
He had informed her that he was separated from his wife and had a son who lived abroad. She saw herself as a partner.
"He also had an affair with Jessena Sheridan and visited her on December 24th last year after leaving his family home."
The investigation found that Mr Williams had spent the morning of Christmas Eve tending to his two grandchildren at the couple's home in Swansea, South Wales.

He told his wife he had to deliver a trailer to Yorkshire and would be back on Christmas morning. His family never saw him alive again.
Miss Sheridan's family received a text message from her on Christmas Day and alerted them when they stopped hearing from her.
They went to their home in Llanelli on December 29th and saw a white cardboard sign on the door.
Mr. Thompson said, "It told them not to come in, call the police and what their intention was."
A Mr. Williams' father was found naked in an upstairs bedroom with multiple stab wounds to his neck and chest and arm injuries while trying to fend off his lover.
On Sunday, December 29, 2019, shortly after 8:30 p.m., police officers were called to the property in Llanelli
Mr. Thompson said, “The walls and floor were badly stained with blood. Several knives of various sizes were found on the floor of the bedroom.
Miss Sheridan's body was found nearby with fatal knife wounds on wrists and arms.
Carmarthenshire Coroner Paul Bennett said, “There are no clear details of what happened, other than that there must have been some sort of argument between Gary and Miss Sheridan.
"The tragedy is not knowing what led to this terrible series of events and what the intent of Mr. Williams' attacker at that time was."
The court later heard that Miss Sheridan had died from self-inflicted knife wounds combined with an overdose.
She had suffered much of her life from mental health problems, compounded by the death of her 13-year-old son Wayne in a road accident in 2004.
Miss Sheridan had asked for help last September because she feared that her relationship with Mr. Williams would end.
Acting coroner Paul Bennett recorded a verdict on the unlawful homicide of Mr. Williams and a narrative conclusion that Miss Sheridan had committed suicide.
"I have found this to be a particularly difficult and tragic case for which evidence can be heard," he said.
& # 39; It is undisputed that Gary Williams led a threefold and somewhat complicated life. In addition to being married, Mr Williams had a partner and also had an affair with Jessena Sheridan, with whom he developed a relationship in 2014.
& # 39; This relationship had been kept a secret by both Gary's wife and partner. This triple existence was administered for many years by Gary who continued his professional and social life.
“He had been able to sever these relationships completely without his wife or longtime partner knowing of his further involvement with Miss Sheridan.
The reality is that he visited Miss Sheridan's home that same day. No clear details are available about what actually happened afterwards, other than that there must have been some sort of altercation between Gary and Miss Sheridan.
"The real tragedy of this case is not knowing what led to this terrible series of events and what the intent of Mr. Williams' attacker at that time was."
Mr Bennett said Miss Sheridan was a "troubled person who has seen many traumatic and tragic events in her life".
A separate investigation into Miss Sheridan took place three hours later in an attempt to separate the two families of the late businessman and his lover.
