But Mr Viafore's kayak began to fill with water and tragically capsized. The 46-year-old was not wearing a life jacket, struggled to stay afloat and drowned, The ABC reports.
Ms Graswal was accused of sabotaging the kayak by secretly removing a drain plug, leading to his death. The 37-year-old woman allegedly watched Mr Viafore drown.
As PEOPLE reports, Ms Graswal has pleaded guilty to criminally neglicant homicide.
Prosecutors have claimed Ms Graswal was motivated by a life insurance plot. They argued she would have been set to receive $250,000 in life insurance benefits after Mr Viafore's death.
According to CBS’s 48 Hours, Ms Graswald was also heard confessing to the crime in a video interrogation. "I wanted him dead and now he's gone. And I'm okay with it," she said.
Grawald had also complained about their relationship, particularly Mr. Viafore’s penchant for pornography and group sex. A court previously heard that Ms Graswald told police she wanted to escape from Mr Viafore's “sex demands and threesome desires".
Her lawyer, Richard Portale, said his client “did not intend to kill him”.
"She didn’t admit she intentionally removed the drain plug so he could die. She had taken it out sometime prior to April 19 and she didn’t know there was this risk. She failed to perceive this risk,” he said.
