C.O.R.E. Intruders

You and your team, along with a hacker have been hired to break into C.O.R.E. Technologies and retrieve a very important piece of technology. You know the doctor and his assistant are at a lunch meeting and your hacker has the security software under control. However, there is nothing you can do about the patrols of on-site security but your hacker can warn you when they are coming. Can you find the package before the doctor returns? Can you stay out of sight if security comes by?
