Task: Question Generation
Input (English): Passage: Ruthless killer Steve Michel is known to the public as "The Claw" for his way of killing his victims with his prosthetic hook. After his accomplices Ryan and Taylor have broken in and stolen furs from the Flawless Furs warehouse, Steve kills the guard with his hook. When the police arrive at the crime scene in the shape of Detective Dick Tracy, he talks to Humphries, who is the owner of the store; Peter Premium, who is a representative for the insurance company; and a man named Cudd, who is the insurance investigator. The insurance company only has twenty-four hours to find the stolen goods, or they have to reimburse the fur company. Tracy and his semi-competent assistant Patton examine the dead body at the morgue and find a note on it stating that there were three perpetrators performing the hit against the warehouse. It also mentions that they used a truck with the name "Daisy" on it. Unfortunately, the three perpetrators disguise the truck before Tracy can find it, and the lead is a dead end. The robbers soon leave their hideout in a local junkyard and go to a nearby bar to phone their boss and get new instructions. As they speak with the boss on the phone, their conversation is overheard by an informant, a blind beggar called Sightless, who goes to pass the information on. Sightless is sloppy and noisy when eavesdropping, and is nearly caught by The Claw. Still, he manages to escape the bar.
Output (English): Which lead is a dead end?
