specimen charges

I've just read an English text recently, but I couldn't understand an expression in it. I'm just wondering if u could explain me the meaning of " two specimen charges" I had looked up in the dictionary, but in vain..The text was about a train driver called Robert Morgen, who caused a serious train crash in which some people died..The confusing sentence says: "Morgan, admitted two specimen charges of manslaughter after the accident on March last year and was sentenced to…"  Thanks very much for ur help in advance..

Hi! That's a tough question. A "charge" is something that one is accused of in a court of law. A "specimen charge" must be a more specific legal term for something one is charged with. "Manslaughter" is type of crime in which one murders someone, but not on purpose. So it sounds like the train driver was accused of accidentally killing two people in the train wreck.
