Pierce County prosecutors on Thursday rested their case against Tyler Savage, the South Hill man on trial in the death of a teenage girl found strangled three years ago.
The defense is scheduled to begin its case Dec. 10.
Savage, 21, is charged with aggravated first-degree murder in the death of Kimberly Daily, who was 16 when she died. He faces life in prison without release if convicted as charged.
Prosecutors contend Savage sexually assaulted and killed the Special Olympian in August 2010.
Defense attorneys say the girl died accidentally during a consensual sex experiment.
The state called Pierce County Medical Examiner Thomas Clark as its last witness.
Clark testified that Daily died of strangulation and had vaginal injuries consistent with sexual assault.
Under questioning from deputy prosecutor Phil Sorensen, Clark said the vaginal injuries most likely occurred while Daily was still alive.
If true, that would be proof of rape and help prosecutors argue that Savage is guilty of aggravated murder.
But Clark conceded on cross examination by defense attorney Les Tolzin that the injuries could have occurred when Daily appeared dead but was still alive after being choked unconscious with her underwear and shirt.
Savage told detectives he touched the girl's vagina after she died to make it appear she was a rape victim.
It is expected that Savage will take the stand in his own defense when the trial resumes.
