"INTEGRITY YOU CAN TRUST - SERVICE YOU CAN COUNT ON" TO: Federal Bureau of Investigation, Suite 400, Crown Plaza Building 1500 Southwest 1st. Avenue Portland, Oregon 97201-5828 (503) 224-4181.
Please respond to the following questions.

1). Ref: The DB Cooper Case. Where in Clark County was the money found? Reason for asking the question. If DB made a night time water jump and drowned, by determining where along the Columbia River where the money was recovered in Clark County, I would be able to bring in a trained cadaver dog and look for the bone fragments remains of the "DB Cooper" case. Possibly locating more evidence for your agents.
What kind of parachute was he jumping? A PCMark111/or Delta? I know it was a specially made competition chute. During this time period the only new Comp chutes were the Paracommander Mark models and the Deltas. I don't believe the squares or strato clouds were made yet.
I need this information to figure glide/drop ratios. (I used to be a[REDACTED] with USPA).
Winds were reported from the west at 25MPH. A delta chute has a forward glide rate of approx. 18-25MPH. A PCM111 12MPH glide ratio. Under canopy from 7,000 feet gives "DB" 6.30 minutes of glide time at 35MPH. (With the wind in his back). If he jumps over amboy and splashes down near CAMAS, figuring water current speed, water temp, weight of chute, harness, suspect, money, he'll drift 1/2 mile unless snagged underwater.
2). Does the FBI hire support K-9 Search staff? For finding evidence and victims? KSA[REDACTED] in the state of Oregon. I have documented more types of searches and[REDACTED] USA.
