My question involves criminal law for the state of: washington

ok i'm going to use the names joe cool and billy bad ass what todays name for there relationship would be domestic partners.

jc & bba had been in a tiff most of the day and jc was fed up with the bickering and told bba to just get the hell out well bba did leave but not b4 he took a large amount of jc grass and oxy. well jc didnt know it was gone until he went to make a sale. jc had called bba and the fight went on bba was not at any place jc could find him. this went on for a couple of days back and forth over the phone jc wanting his stuff back and bba useing it as bargaining power to get his card collection.

well bba is rolling around town in his truck that you could spot a mile away. small town and bba has his lic revoked and the law knows him and his truck very well. needless to say that he was passing the donut shop and barny fife spotted him and when he was stopped barney not only smelt the weed, it was in plain sight, 5 large zip lock bags full. after he was brought to the jail in the next town(we dont have a jail in our town) they found aprox 150 pills on him. so he got booked in on driving on a revoked which he is on probation also. dope that he had stolen. so he then calls jc collect and tells jc hes back in jail and the stuff is gone now the conversation is so wishy washy on whos stuff it is but not admitting it was jc half the conversation you caan tell whos stuff it was.

now my question is becouse they are domestic partners can they use any of that info to file charges on jc where does that privy communication become a factor not to testify or not be able to use against jc as he was not in custody it was bba in jail.does it apply to both or one thats in custody and not useable to the one out of jail....please help
