Autopsy: Jailed Texas woman died from blood clots




DALLAS (AP) — A woman who went into convulsions at a Texas jail in May died after blood clots traveled into her lung, according to an autopsy.

The Harris County Institute of Forensics ruled that 22-year-old Symone Marshall died of pulmonary thromboemboli due to deep vein thrombosis. Her manner of death was ruled natural, according to the autopsy, which was released Tuesday.

Authorities have said Marshall had been in Walker County jail in Huntsville for two weeks when she died on May 10 after being taken to a hospital. She was being held on $5,000 bond after Texas Department of Public Safety officers arrested her following a single-vehicle rollover on April 26. She was accused of possession of a controlled substance and failure to identify by giving false information.

Authorities have said Marshall declined medical treatment immediately following the wreck and was later seen by jail medical staff after complaining of loss of appetite.

The case drew attention on social media in May, with some questioning the circumstances of her death.

The autopsy said that such clots can develop because of inherited or acquired conditions and that an inherited condition can't be ruled out in Marshall's case. The autopsy, which noted Marshall had no evidence of injuries, said she had a family member who died from pulmonary thromboembolism.

Walker County Sheriff Clint McRae has said emergency medical responders were called after the wreck. The sheriff said Marshall and another person exited the car and walked around. He said neither had visible injuries and both denied medical treatment.

The sheriff said while Marshall was jailed, she was seen by medical staff after experiencing a loss of appetite and was at one point seen by a doctor. Marshall's sister, Honey Marshall, had told Houston television station KHOU that her sister complained to her from jail that her head was hurting and she felt like blacking out.

Dr. Judy Melinek, an independent forensic pathologist from San Francisco who is unaffiliated with the case, reviewed the autopsy.

"Family history suggests that the blood clots were at least, in part, due to genetics, but without genetic studies on her blood it would be speculative to say with any certainty," she said.

She said it doesn't appear that the death would have been the direct result of any traumatic injuries from the vehicle accident, but noted that immobility is a "major risk factor" for clots to develop. For example, if Marshall were immobilized from pain following the accident, that could have been an indirect contributor, she said.

The autopsy does not mention the accident or how active Marshall was in jail. The sheriff did not return a call from The Associated Press Wednesday.

The Texas Rangers said their investigation into the death was completed last month and the results were forwarded to the Walker County district attorney's office, which did not respond to a message left by the AP.
