Charges of felony arson and forgery are included as part of an investigation Pleasanton police submitted to the Alameda County District after the incident.
Zuffa is reportedly recovering from extensive burns in an undisclosed location.
Since the explosion on Dec. 8, 2008, the burned out home has been an eyesore in the neighborhood and also for parishioners at St. Augustine Catholic Church, which has its main driveway located just across Angela Street from the home.
Sgt. Jim Knox of the Pleasanton Police Department said police wrapped up their investigation "a few months ago" and sent the paperwork off to the DA's office for review.
Zuffa and her husband Keith filed for Chapter 13 bankruptcy in June 2008, according to public records. Records also show the home, at one time valued at nearly $1 million, was sold for $75,000 in a foreclosure sale on in September 2008 to Marilyn and Richard Greenberg in the name of the Greenberg Trust.
Wrecking crews demolished the house but left the undamaged foundation and utility connections in place. It's expected the lot will be sold and a new home constructed on the site.
