Harry Burkhart was charged Wednesday with setting a series of fires across the Los Angeles area.

Prosecutors said they were filing a total of 37 counts, adding that they are continuing to investigate the fires and that more charges could be coming soon.

“After reviewing the available evidence, we filed 28 counts of arson of property and nine counts of arson of an inhabited structure,” Dist. Atty. Steve Cooley said in a statement. “The complaint also alleges that the arson was caused by use of a device designed to accelerate the fire. If found true, the allegation could mean additional custody time for the defendant."

It was not immediately clear which fires he was charged with but officials said the criminal counts involve 13 fires.

Hours before the charges were filed, prosecutors in Germany said Burkhart was suspected of torching a home owned by his family six days before he arrived in the United States.
