Burkhart is now charged with 75 counts of arson of property, 19 counts arson of an inhabited structure, two counts of arson of an uninhabited structure, two counts of attempt to burn and two counts of possession of flammable material, according to the D.A.'s Office. The charges involve 49 arson fires in Hollywood, West Hollywood, Sherman Oaks and Los Angeles between Dec. 30 and Jan. 2.
Burkhart appeared in court Tuesday afternoon and pleaded not guilty to all 100 counts. His bail, originally set at $2.8 million, was raised to $7.5 million.
Many of the fires were set underneath automobiles parked in carports of apartment buildings. Fire spread to property and buildings in several of the incidents.
No one was injured in the string of arsons, but the city estimates damages in the $3 million.
Burkhart was arrested in the early morning of January 2, when a reserve sheriff's deputy saw a minivan matching the suspect vehicle description in Hollywood. Burkhart, who was driving, was pulled over and suspicious materials were found in the vehicle.
Burkhart allegedly told police he hated America when he was arrested. Police suspect he may have been retaliating after his mother was arrested in Hollywood and held on an extradition warrant for outstanding crimes in Germany.
Harry Burkhart is also wanted in Frankfurt, Germany, on suspicion of setting fire to his house in an attempt to collect insurance money.
Burkhart's mother, Dorothee Burkhart, claims her son is mentally ill and not capable of setting the fires. She is currently held without bail and is scheduled to return to federal court Jan. 25. The two lived together in a one-bedroom apartment in Hollywood.
