The cause of death, the medical examiner confirmed, was a stab wound to the chest.

On Wednesday, officials from the Bexar County Sheriff's Office, including personnel from the missing persons and homicide divisions, recovered the body of a woman in a wooded area near Wildhorse HOA Sports Park.

Bexar County Sheriff Javier Salazar addressed the investigation on Thursday, stating that while it's possible Siles' death was self-inflicted, "it’s just as likely at this point that someone else is responsible for this."
