According to the testimony of the Knox County Acting Medical Examiner Dr. Darinka Mileusnic-Polchan at the subsequent trial of Eric Boyd, Newsom was repeatedly raped and then blindfolded, gagged, arms and feet bound and his head covered. Barefoot, he was either led or dragged outside the house to a set of nearby railroad tracks. He was shot in the back of the head, the neck, and the back, and his body then set on fire. Christian's death would come only after hours of sexual torture, medical examiner Mileusnic-Polchan testified.
Christian suffered horrific injuries to her vagina, anus and mouth. She was not only raped but savaged with "an object," possibly a broken chair leg, the doctor testified. She was beaten in the head. Some type of chemical was poured down her throat, and her body, including her bleeding and battered genital area, likely scrubbed with the same solution - all while Christian was alive, the forensic expert said.
She was then "hog-tied," with curtains and strips of bedding, her face covered tightly with a small trash bag and her body stashed inside five large trash bags before being placed inside a large trash can and covered with sheets. Christian died slowly, suffocating, the medical examiner said.
