Larry Dunn, who has not yet tested positive for HIV, visited Cicely Lee Bolden's home for unprotected sex one last time in September 2012, and then took a knife from the kitchen and stabbed Bolden in the neck as she laid in bed, according to his video testimony that was played in court Tuesday at his murder trial, the report said.
"She didn't see it until it was in her throat," Dunn told police, the report said. "She wasn't very strong."
Her body was discovered by her two young children in bed, naked from the waist down, the report said.
If convicted, Dunn, who said he was worried he infected his wife, faces up to life in prison in the killing. His attorney will try to prove he acted with "sudden passion," which carries a 20-year sentence, the report said.
Dunn initially denied killing Bolden when he was initially confronted by police, the report said. Brian Tabor, a Dallas detective, told the court that Dunn was convincing, but he continued pressing the suspect because of his likely connection, the report said. He admitted to the crime in a second interview, the report said.
