"The reconstruction of the murder victim from skeletal remains will be more accurate now, helping to identify that person. DNA left at a crime scene can give forensic scientists a clue as to the perps skin color and hair color, helping them to identify him."
The real answer is yes and no. Skull shapes do help determine race and from there you can guess at hair coloring and eyes etc.. DNA is helpful provided it is not degraded. If the crime if ancient any of this information is worthless since you have no database to draw from and both would be dead by now.
In forensic science we often have a DNA profile however no one to match it up to so it doesn't really "identify" the perp or the victim UNLESS you have something to match it to.
