SHINGLETOWN, Calif. -

Court records reveal a long criminal history for the at-large suspect in a triple homicide, 45-year-old Shane Franklin Miller – just not in Shasta, Tehama or Butte counties.

Miller is a suspect in the homicide of his wife, Sandy, 34, and daughters, Shelby, 8, and Shasta, 4. The woman and two children were found dead with multiple gun shot wounds in their home on Alpine Way in Shingletown Tuesday night.

Miller was released from federal prison on May 18, 2007 after being tried in the California Northern District U.S. District Court. He plead guilty to being a felon in possession of a firearm back in 2003 and was sentenced to four years in prison.

The case also involved charges of conspiracy to manufacture and distribute marijuana, manufacture of and possession with intent to distribute marijuana, possession of a machine gun and money laundering. All of these charges were dismissed.

Miller was one of two defendants in this case which also included a Terry Franklin Miller. It is unknown whether the Millers were relatives.

Miller also had a record in both Humboldt and Mendocino counties. According to the Times-Standard, in Humboldt County Miller was charged with a felony hit-and-run case in 1996, a misdemeanor case of driving on a suspended license in 1994, being drunk in public and a misdemeanor DUI in 1993.

The spokeswoman also said that Miller had been convicted in 1996 of felony marijuana cultivation.
