A woman whose body was found in Redington Pass in August died of an accidental drug overdose, an autopsy report released late Tuesday reveals.

The death of Melissa Sparks, 28, is “ascribed to a methamphetamine intoxication,” the report stated.

Sparks’ body was found Aug. 14 in a rural area off Redington Road on Tucson’s far east side. Two men were arrested on suspicion of manslaughter in her death, but the charges were dropped two weeks later for insufficient evidence.

The men were with Sparks the day she died. They flagged down a car in the area and asked the driver to call police because their friend had committed suicide. Deputies detained the men for questioning and later arrested them.

The men admitted to drinking and doing drugs with Sparks the night before she died, the sheriff’s report stated.

Court documents noted that Sparks had bruising around her neck described as “obvious ligature marks.”

The men told investigators they had strangled Sparks during sex.

The autopsy report revealed Sparks had “a patterned pale indentation consisting of multiple loop-shaped areas of discoloration” encircling her neck, but she did not die of strangulation. She also had scrapes and bruises.
