It's early Monday morning. Sun is not up yet. Greg is sitting in a silver Audi, in front of Jeff's apartment building and holding a new type of pneumatic syringe gun which Rebecca got him from her veterinarian friend. The gun has space for six medicine dosages, that means he has six shots for four bodyguards. He tried it out in Rebecca's garden, and he is confident that if he gets within five feet, he will definitely hit the target.
The gun is small enough to almost fit in his palm. 'Perfect, it will stay hidden.' The gun makes some noise, but if used on the street, regular noise from traffic and people will cover up the sound.
Greg adjusted air pressured chambers to deliver enough anesthetic to knock down a grown-up person for few hours. Once needle hits the target, it takes about a second to administer the medicine from the chamber and in no more than five seconds, target will be sedated.
