LA Arson Suspect Motivated by Deportation? The prime suspect in the series of up to 55 blazes in the Los Angeles area told authorities upon his detention, "I hate America," according to ABC News sources directly involved in the case. The sources told ABC News exclusively that the man identified by police as a "person of interest" is now considered a "prime suspect" and is believed to be a German national who may have been motivated by a deportation hearing against his mother that took place in LA County about a week and a half ago. The information was given to the intelligence and operational task forces involved in the manhunt from the state department, according to the sources. Earlier today, police seized flammable materials during the search of a mini-van which matched the materials used in the blazes, according to sources. Police arrested the man this morning following 11 fires ignited overnight, the latest in a series of vehicle and carport fires around Hollywood and West Hollywood since Dec. 30. Sources said that the suspect is being uncooperative and will be asked to sit for a polygraph as part of the investigation. Warrants for a search of the suspect's residence were in the process of being executed. Although this suspect is considered the most likely person to have set all the blazes, a second suspect was still being detained by authorities and interrogated in connection with them. Los Angeles Police Chief Charlie Beck said today he believed officers apprehended the sole arsonist. I feel very good that we've got the right guy. [The suspect] had the right stuff in his van, and we are very confident we found our man," Beck said. This morning, arson investigators and sheriff deputies swarmed the scene where the man -- said to resemble the person in a surveillance video released Sunday by Los Angeles police -- was stopped and detained. He was the fourth person detained in connection with the tidal wave of arson fires that has engulfed the city. Capt. Moore confirmed that 10 of the fires set overnight Sunday were in Los Angeles, while two were in West Hollywood.
