As more facts trickle in about the man accused of deliberately setting a wave of fires across聽Los Angeles, crime analysts are trying to zero in on a possible motive and what, if any, lessons can be learned by both law enforcement and the media.聽

Harry Burkhart was arrested Monday in connection with more than 50 fires set over the course of 4 days.

Experts say聽that Mr. Burkhart's motives 鈥� even if stated 鈥� may never really be聽known. They could range from the political to the personal, and could involve everything from unresolved childhood issues, to thrill seeking, to besting the authorities in a cat and mouse game. Or all of the above.

And pinpointing a motive is made even more difficult by ravaged crime scenes.

鈥淎rson is a very difficult crime to investigate and prove because a lot of evidence is destroyed,鈥� says Robert Rowe,聽President of Pyrocop Inc., a fire forensics firm based in聽Long Beach. 鈥淚nvestigators need to be extremely diligent in building their case to guide a jury step by step.鈥�

Still, there are clues that can lead investigators to a motive.

Judging by the age of the suspect, 24, some surmise that he acted alone and out of anger, as fits the pattern of younger arsonists. Older arsonists, however, typically operate with a profit motive 鈥� cashing in on insurance scams 鈥� and many times work in groups.

鈥淩esearch shows that young arsonists have very low social skills and are attracted to the high, immediate emotional payoff of fires,鈥� says Elizabeth Dowdell, a professor at the Villanova University College of Nursing in Pennsylvania with background聽in forensic research. 鈥淔ire is so destructive that it can give the instant gratification these people feel over a perceived wrong.鈥�

Speculation shifted Tuesday night to Mr. Burkhart's mother, who reportedly faces 19 counts of fraud and embezzlement in聽Germany.

According to the federal Immigration and Customs Enforcement agency (ICE),聽Dorothee Burkhart has no legal immigration status now, having last entered the country lawfully in 2007.

A man who identified himself as Ms. Burkhart鈥檚 son appeared at a court hearing last week after the elder Burkhart had been taken into custody on an arrest warrant issued by German authorities. Demanding that she be let go, the son screamed and cursed, aiming at least one epithet at 鈥渢he United States,鈥� until court marshals removed him from the building, Thom Mrozek, a spokesman for the United States attorney鈥檚 office in Los Angeles, told the Los Angeles Times Wednesday. The younger Burkhart was briefly detained, but not arrested.

Charged with one count of arson 鈥� though more are expected 鈥� Harry Burkhart is being held without bail and is scheduled to appear in court Wednesday. After his arrest Monday, ABC reported that Burkhart smiled and said, 鈥淚 hate聽America.鈥�

Police continued to look for other suspects who may be involved in the聽four-day arson spree. But no more fires have been reported since Mr. Burkhart鈥檚 arrest.聽

Los Angeles County Sheriff Lee Baca called whoever set the fires, 鈥減erhaps the most dangerous arsonist in the聽County聽of聽L.A. that I can recall.鈥�

Media and law enforcement can learn lessons from the arson spree, analysts say.

Both perform a public disservice when they use such terms as "most,鈥� "worst,鈥� or 鈥渇astest鈥� because that might feed the perpetrator鈥檚 need for grandiosity and spur others to make an even greater statement merely by topping them,聽says James Alan Fox, a criminologist at聽Northeastern聽University in Boston who studies serial crime.

鈥淩ecords are made to be broken so I find it troubling when officials speak in those terms,鈥� he says. Fox also discourages comments emphasizing the fires were set mere minutes apart. Such comments, he says, could encourage copycatting.

鈥淭here is a fine line between between shedding light on crime and spotlighting the criminal,鈥� says Fox. One of the lessons, as he sees it, is that society should be careful about on the one hand making the criminal more important than he is, and on the other hand humanizing him too much. As the case has continued to attract global attention, Fox says, 鈥淵ou want to be sure not to go overboard in investigating and reporting the biographical sketches of such perpetrators.鈥�
