Well, let us hope that the DA's office and the police are not as cold-hearted as you, and value her life more.  

Her killer or killers need to be brought to justice.  It is not uncommon for drug dealers to kill addicts or low level dealers that the government has leverage with, in order to protect themselves from prosecution.   That could easily be a potential motive for murder.  

Bringing justice for this young woman should be everyone's focus.
