These are the survival instructions left in the "capsule" by Gary Steven Krist and Ruth Eisemann - Schier for their kidnap victim Barbara Mackle, "The Girl in the Box". After her family paid a $500, 000 ransom, the FBI received a phone call informing them of her location. She was rescued after being buried alive in the box for 83 hours.

   DO NOT BE ALARMED. YOU ARE SAFE.
   YOU ARE PRESENTLY INSIDE A FIBERGLASS REINFORCED PLYWOOD CAPSULE BURIED BENEATH THE GROUND NEAR THE HOUSE IN WHICH YOUR KIDNAPPERS ARE STAYING. YOUR STATUS WILL BE CHECKED APPROXIMATELY EVERY 2 HOURS.
   THE CAPSULE IS QUITE STRONG, YOU WILL NOT BE ABLE TO BREAK IT OPEN. BE ADVISED, HOWEVER, THAT YOU ARE BENEATH THE WATER TABLE. IF YOU BREAK OPEN A SEAM YOU WOULD DROWN BEFORE WE COULD DIG YOU OUT. THE CAPSULE INSTRUMENTATION CONTAINS A WATER SENSITIVE SWITCH WHICH WILL WARN US IF THE WATER ENTERS THE CAPSULE TO A DANGEROUS DEGREE.
   YOUR LIFE DEPENDS ON THE AIR DELIVERED TO YOUR CHAMBER VIA THE VENTILATION FAN. THIS FAN IS POWERED BY A LEAD-ACID STORAGE BATTERY CAPABLE OF SUPPLYING THE FAN MOTOR WITH POWER FOR 270 HOURS. HOWEVER, THE USE OF THE LIGHT AND OTHER SYSTEMS FOR ONLY A FEW HOURS COUPLED WITH THE HIGHER AMPERAGE DRAIN WILL REDUCE THIS FIGURE TO ONLY ONE WEEK OF SAFETY.
   SHOULD THE AIR SUPPLIED PROVE TO BE TOO MUCH YOU CAN PARTLY BLOCK THE AIR OUTLET WITH A PIECE OF PAPER. A MUFFLER HAS BEEN PLACED IN THE AIR PASSAGE TO PREVENT ANY NOISE YOU MAKE FROM REACHING THE SURFACE: IF WE DETECT ANY COMMOTION WHICH WE FEEL IS DANGEROUS, WE WILL INTRODUCE ETHER TO THE AIR INTAKE AND PUT YOU TO SLEEP.
   THE FAN OPERATES ON 6 VOLTS. IT HAS A SWITCH WITH TWO POSITIONS TO SWITCH BETWEEN THE TWO AVAILABLE CIRCUITS. SHOULD ONE CIRCUIT FAIL TURN TO THE OTHER.
   THE BOX HAS A PUMP WHICH WILL EVACUATE ANY ACCIDENTAL LEAKAGE FROM THE BOX WHEN YOU TURN THE PUMP SWITCH ON TO THE "ON" POSITION. THIS PUMP USES 15 TIMES AS MUCH POWER AS YOUR VENTILATION FAN (7.5 AMPS); YOUR LIFE SUPPORT BATTERY WILL NOT ALLOW USE OF THE PUMP EXCEPT FOR EMERGENCY WATER EVACUATION.
   THE LIGHT USES 2.5 TIMES THE AMPERAGE OF THE AIR CIRCULATION SYSTEM. USE OF THE LIGHT WHEN NOT NECESSARY WILL CUT YOUR BATTERY SAFETY MARGIN SUBSTANTIALLY. IF YOU USE THE LIGHT CONTINUOUSLY YOUR LIFE EXPECTANCY WILL BE CUT TO ONE THIRD OF THE WEEK WE HAVE ALLOTTED YOU BEFORE YOU ARE RELEASED.
   YOUR CAPSULE CONTAINS A WATER JUG WITH THREE GALLONS OF WATER AND A TUBE FROM WHICH TO DRINK IT. BE CAREFUL TO BLOW THE WATER FROM THE TUBE WHEN YOU ARE FINISHED DRINKING TO AVOID SIPHONING THE WATER ONTO THE FLOOR WHEN THE TUBE END DROPS BELOW THE WATER LEVEL.
   YOUR CAPSULE CONTAINS A BUCKET FOR REFUSE AND THE PRODUCTS OF YOUR BOWEL MOVEMENTS. THE BUCKET HAS AN ANTIBACTERIAL SOLUTION IN IT: DON'T TIP IT OVER. THE LID SEALS TIGHTLY TO PREVENT THE ESCAPE OF ODORS. A ROLL OF WAX PAPER IS PROVIDED - USE IT TO PREVENT SOLID WASTE FROM CONTAMINATING YOUR BED. KOTEX IS PROVIDED SHOULD YOU NEED IT.
   BLANKETS AND A MAT ARE PROVIDED. YOUR WARMTH DEPENDS ON BODY HEAT SO REGULATE THE AIR TO PREVENT LOSS OF HEAT FROM THE CAPSULE.
   A CASE OF CANDY IS PROVIDED TO FURNISH ENERGY TO YOUR BODY.
   TRANQUILIZERS ARE PROVIDED TO AID YOU IN SLEEPING - THE BEST WAY YOU HAVE TO PASS THE TIME.
   THE VENTILATION SYSTEM IS DOUBLY SCREENED TO PREVENT INSECTS OR ANIMALS FROM ENTERING THE CAPSULE AREA. YOU RISK BEING EATEN BY ANTS SHOULD YOU BREAK THESE PROTECTION SCREENS.
   THE ELECTRICAL COMPONENTS BEHIND THESE SCREENS ARE DELICATE AND THEY SUPPORT YOUR LIFE. DON'T ATTEMPT TO TOUCH THESE CIRCUITS.
   WE'RE SURE YOUR FATHER WILL PAY THE RANSOM WE HAVE ASKED IN LESS THAN ONE WEEK. WHEN YOUR FATHER PAYS THE RANSOM WE WILL TELL HIM WHERE YOU ARE AND HE'LL COME FOR YOU. SHOULD HE FAIL TO PAY WE WILL RELEASE YOU, SO BE CALM AND REST - YOU'LL BE HOME FOR CHRISTMAS ONE WAY OR THE OTHER.
