To date, LAFD has been handling two different arson cases. They confirmed that a first round of fires was set by one person; they believe that suspect is 22-year-old Samuel Arrington of Sunland.
A second round of fifty-five fires were set by a separate person, LAFD tells news. Investigators claim A total of 55 fires of concern have broke out in the Los Angeles area over the last four days from 12/30/11 to 01/02/12. Forty-five fires have erupted in the Los Angeles area, nine in West Hollywood, and one in Burbank.
I believe Arrington was lighting trashcan fires outside of a greedymart, and then tried to light some diesel/gas tanks on fire when he was chased down and caught. If fact, he set trash cans ablaze along a five-block stretch of Sunset Boulevard. He was hard not to miss. I believe Arrington was a typical copycat nutcase, who got caught up in all the hub bub, and just couldn't help himself.
