11. General Facts
Because exercise strengthens the point where the muscle is attached to the bone, a large mark where the muscle was attached is a sign that the person was muscular.
Larger muscle-attachment scars on the bones of one arm as compared to the other indicate whether the person was right- or lefthanded.
A scar on a bone is a sign of a healed fracture.
Frequent, repeated stress on a joint can wear down the cartilage of the joint, causing the joint surface to appear smooth and shiny.
A person’s height can be calculated with this equation:
Height (cm) = (2.26 × femur length)

12. Skeletal Remains Several tendon marks on femur and humerus
Muscle scars on left radius and ulna
Joints and teeth in good condition
Several fractures on femur, pelvis, an radius
Femur size = 49 cm
Narrow pelvis
Average size
Square chin, round cranium, oval eye socket
Most bones fused except for clavicle and parts of the cranium, few small spaces between carpals
Full set of teeth, no wisdom teeth

"The Masters Case"
In 1964 Butch Masters, 16, was "accidentally" killed by his father after being pushed down a flight of stairs. His father then buried him in a shallow grave, behind a building on their farm, where he remained buried until His body was found by workers repairing an underground pipe. The Master's family rented an apartment over the garage on the property. The family had long since moved to the southern states.
McHenry County Coroner Marlene Lantz was contacted by the McHenry County Sheriff's Police to process the death scene. The scene was processed for the human remains and any items of evidential value. The scene indicated that the deceased was buried by someone "close" to him, either family or friend. The victim was buried without clothing and was positioned as though being "laid out" in a casket. Once the remains had been properly exhumed and secured, they were examined by Dr. Clyde Snow, an Internationally renown Forensic Anthropologist. Dr. Snow was able to build an accurate description of the person but didn't know who he was. The case was put on hold pending a positive identification of the deceased.
In 1994 the deceased's aunt had contacted the local police authorities, trying to find the whereabouts of her nephew. His father had told people he moved out of the area in 1964 and went to work in Alaska. The physical description Dr. Snow developed from the remains fit the missing brother. A DNA test on the family revealed the recovered remains were in fact that of Butch Masters. This DNA test also revealed that John Masters, his father, was not his biological father!
John Masters was interviewed and confessed to the crime that occurred 30 years previous. He was convicted of manslaughter and sentenced to 5 years probation.
