A capital murder trial began Wednesday for a Dallas man accused of killing two women in July 2015 while in a cocaine-induced stupor.

Leonard Mornes, 60, first told police that he shot Bridgitte Manning and Jacqueline Armstead after they attempted to break into his Red Bird home.

But jurors were shown a bizarre and winding interrogation video that told a different story.

Initially, Mornes would tell homicide detectives only one thing: "Don't follow the trail that they put out there for you to follow. Look for twins."

The self-proclaimed Gospel preacher said he had been framed and evidence had been planted in his home to make him look guilty, including drugs and the bodies of the two women.

"Whoever is dead in my house was killed and brought there," he said.

Mornes later said that on the day of the slayings he had been at his home smoking crack cocaine with two women he believed to be federal agents.

He'd been followed for 12 years, he said, and regularly heard voices coming from his attic. He believed these women were in on it.

Mornes said the women told him they were there to smoke crack and have sex, but at another point in the video he said they told him they were there because they were federal agents and they were going to clean his house.

He bought the drugs with one of the women and they smoked together while she told him he was being investigated and that she came to help, he said.

At one point, one of the women had blood running down her legs, Mornes told detectives, and she said it was from her period.

But he said he became paranoid that the woman had put someone else's blood on her legs so she could plant it in his home to frame him.

When the women tried to flee his house, he said, he grabbed his guns and began shooting. But he didn't think he was hitting them since he saw no blood, and he later said he believed he was firing blanks.

When a detective asked him why there were open bottles of lubricants and sex toys on the bed in the bedroom, he said he always kept those things on his bed.

He denied having sex with the women, but he said he believes he did have sex with dogs.

"They brought the dogs in the house, and I think the dogs had sex with me," he told detectives as he pulled up his pant leg to show a scratch he believes came from the animals. He attributed a flea problem in his house to the dogs.

As jurors watched the hours-long video Wednesday, Mornes struggled to stay awake and at one point fell asleep and began to snore in the courtroom.

The trial is expected to continue through the end of the week.
