A phone charger and baby wipes don't bode suicide to me. More like not going back to get a charger, cleaning up in the rough and some more time making arrangement in the car? What would you need to clean if you're planning on suicide?
Could taking the test have been a stresser?
There was a computer programmer/tech guy from the Seattle area that went missing awhile back. They found his car in the parking lot of Deception Pass State Park too. They searched and searched. My understanding is it was eventually assumed he had jumped. Being local, its more often than not that they never find the person. The water is so fast and so deep there.
Sorry but you are incorrect. Jeremiah Foco is the missing programmer from Seattle and his car was found parked in the garage of his apartment building, not at Deception Pass. No one has any idea what happened to Jeremiah but yes, suicide is a possibility.
