A tenement building explodes and the lone victim is Joseph Haden. The building was rent controlled and there had been a tenant strike, so the police initially suspect arson. But the landlord doesn't have insurance, ruling out their arson theory, and the medical examiner discovers that Haden's neck was broken and he was tied up before the explosion happened. Trying to figure out Haden is even more difficult. He didn't appear to have a family or a girlfriend and never got any substantial mail. He worked at the Jiffy Job service station making minimum wage, yet had $90,000 in the bank. Briscoe and Green do some more digging and find out that Haden was using an alias, and his real name was Yusuf Haddad.
