>> i started in the boulder district attorney's office in 2009. i started under the new administration with d.a. stan garnett, and sure enough, in the summer of 2009, dave hayes showed up on our doorstep with boxes upon boxes upon boxes of the investigative file into the murder of sid wells. in december of 2010, 27 years after sid wells was murdered, the d.a. signed off on an arrest warrant accusing thayne smika of murder in the first degree. >> after getting the warrant, we put together a coordinated search which included sending detectives to every place where there was members of the smika family or close friends of the smika family. unfortunately, the family without exception told us they did not know where thayne was and did not know how to locate him. >> i think mistakes were made. i think this family has suffered what my family did, incompetence, bad judgment, mistakes, and that precluded the real bad guy, the guy that killed sid, from facing justice. >> well, sid's been gone for 30 years. the things he's missed out on, while thayne is out there
