The case against Sandra Bullock's alleged stalker was elevated to new heights this week after investigators reportedly found an "arsenal of weapons" in his Montrose, Calif., home.

Joshua Corbett not only faces a stalking charge after breaking into the actress' Los Angeles home, but an additional 19 felony counts for possession of illegal weapons.

According to the Los Angeles County district attorney's office, those charges against the 39-year-old include 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.

Sandra's LA home which suspect Joshua Corbett allegedly broke into on June 8

Though his bond was initially set at $185,000 when Joshua pleaded not guilty last week to stalking, a judge has since raised it to $2.2 million after the disturbing discovery. He is currently being held at the Los Angeles County jail.

Arrested in the early morning hours of June 8, the suspect allegedly climbed a barbed wire and chain-link fence surrounding Sandra's property before breaking into her home. Investigators say he could have spent more than an hour inside before being found.

While the Miss Congeniality star was home at the time, it is unknown whether her 4-year-old son Louis was with her.

If convicted, Joshua faces a maximum 12 years in prison, Deputy District Attorney Wendy Segall tells reporters.
