I just talked to Lane County Jail where Daniel McGowan is being held. They say he can get letters with just pen and paper or print, but nothing inside, no glitter, etc. Also standard postcards are allowed. They said if inmates get enough glitter it can be a weapon for eyes so they are not allowed anything with glitter on it.
They said we can send pictures but not polaroid pictures as they have two parts where things can be hidden.
No incoming calls to inmates are allowed but the inmates can call you collect. So that is another option.
Visitation seems improbable for anyone outside of family and attorney. Apparentyly they get to list 3 people on a visit list and they can change those 3 people every 4 weeks. Depending on the classification of the inmate, they can have 1-3 visits a week most commonly, outside of attorney visits, the jail said.
They said he can receive money orders in mail and then the jail guards have him sign it and it goes on his tab for stamps, etc thus sending a money order with your letter is not a bad idea.
Also, they said their address was W. 5th Avenue, not 5th Street as had been previously posted on the internet elsewhere.
So, Daniel's address right now is
Lane County Jail
101 West 5th Avenue
Eugene, Or 97401
Send him a plain letter without glitter, or a photo but not a polaroid!
