Los Angeles (CNN) -- The man arrested at Sandra Bullock's home last week allegedly owns "an arsenal of weapons" that included a half dozen illegal machine guns.
Joshua Corbett, who was charged with stalking Bullock, burglarizing her home and possessing one illegal gun, now faces much more serious charges, according to the Los Angeles County district attorney's office.

The discovery of the arsenal during a search of Corbett's Montrose, California, home has led to 19 felony counts, including seven counts of possession of a machine gun, two counts of possession of an assault weapon and 10 counts of possession of a destructive device, the prosecutor's spokeswoman said.
