Houston was taken to a hospital and later transferred to an extended-care facility. His condition improved, but on August 29, he experienced breathing problems. He died a day later.
The Jackson County Medical Examiner ruled Houston's death a homicide due to a closed head injury with complications.
On September 8, a witness told police that 41-year-old Lisa Wilson had admitted stealing the guns and money from Houston. In an interview with police on Thursday, Wilson told police a sordid story of sex for money and betrayal.
Wilson told police that she saw Houston sitting on his porch. Three times before, she had traded sex for money with Houston. On this day, they agreed to $60 for sex. She said they went inside Houston's home, and she went into the bathroom. When she came out of the bathroom, she said Houston was holding a handgun and demanding his $60 back.
Wilson said she gave Houston the money. She said he told her to take off her clothes, and he set down the handgun. Wilson ran. Houston chased her, naked but unarmed. Wilson reached the front door but hit Houston with a lamp. She wasn't sure how many times she hit him, but it was more than once. Houston went down "moaning."
Wilson admitted running upstairs and taking Houston's guns and an envelope with $700 to $800 in it.
Wilson is charged with second-degree murder and armed criminal action.
