An owner abandoned his truck in an alley in Queens, New York. In spite of repeated complaints to the NYPD, the truck was allowed to remain in the alley. After several months, it was stripped of most of the parts that could be removed. Bobo Tannenbaum, age 10, was walking down the alley when the truck's gas tank exploded. The flames from the explosion set fire to Bobo's clothing, and he was severely burned. What legal theory or theories may serve as the basis of Bobo and his family's lawsuit?
