A man from Florida, accused of killing his childhood best friend, recounted on Tuesday the details of how he murdered his friend so he could be with the man's wife. The accused, identified as Brian Winchester, cried in court as he described the details.

Brian, on Tuesday, testified against his friend's wife and lover Denise Williams, who is also on trial for allegedly plotting the death of her first husband Mike Williams. Reports state that Mike disappeared in 2000 while on a boating trip to Lake Seminole. Denise and Brian are now accused of plotting his murder by staging a boat accident. The duo reportedly also collected $1.75 million in insurance policy after Mike's death, according to the New York Post.

Authorities at the time thought Mike was eaten by alligators after falling off a fishing boat, however, his body was discovered 17 years later buried by the lake. It was later revealed that he had died from a shotgun wound to the head.

Brian, in 2017, confessed to killing his best friend, saying he first pushed him overboard in an attempt to drown him, however, Mike managed to stay afloat by swimming to a stump in the lake.

In his repeated confession on Tuesday, Brian said: "He started to yell and I didn't know how to get out of that situation. I had my gun in the boat, and so I loaded my gun and I just made one or two circles around and I ended up circling closer towards him and he was in the water, and as I passed by, I shot him."

According to prosecutors, Denise and Brian were involved in a three-year affair at the time of Mike's death. Mike and Brian were friends since middle school. However, the latter said that he didn't fall for Denise until he and his first wife, Kathy, began going on double dates with them in Tallahassee.

"We just connected like nobody else," he said of their relationship. "It snowballed really fast." The duo reportedly got married five years after Mike's alleged disappearance in 2005, and later separated in 2016.

Brian, while describing the search for Mike's body, broke in tears: "I think [my dad and I] were the last ones. My dad didn't want to give up," Brian said. "He loved Mike."

Reports state that Mike's body was found last year after Brian pleaded no contest to kidnapping Denise at gunpoint two years ago. He was then sentenced to 20 years in prison. Prosecutors then offered him immunity from murder charges if he gave them information about Mike's disappearance.

Denise was subsequently arrested in May last year on charges of murder and conspiracy. "Denise really didn't have to do a whole lot other than come up with an alibi for herself and make sure that Mike went," Brian said in court. If Denise is convicted, she faces a life term in prison.
