What I heard last night was, LE was directed to this guy by an officer of the court who recognized him from the video that was released. At first it was reported that he did this because of 'immigration' problems. It's not so much immigration problems as his mom was arrested because of a warrant out of Germany. He went into the courtroom, the week prior, where her hearing was being conducted and caused quite a ruckus. That's how the officer of the court remembered him....
JMHO

Hollywood arson suspect set to be in court
Authorities said he went on the rampage because of the legal troubles of his mother, Dorothee Burkhart. They said he started the fires just a day after she was arrested on 19 charges of fraud in Germany, including failure to pay for breast augmentation and failure to return security deposits on apartments she rented to tenants.
Federal agents helped identify Burkhart on surveillance tapes because he had a big outburst during his mother's first court appearance for her case.
