My question involves criminal law for the state of: Wisconsin
I recently was caught up in a sting operation where while returning from Illinois, the car in which I was a passenger was was pulled over. after a search of the vehicle and all the persons in the vehicle cocaine and paraphanelia were found on everyone but me. a significant amount of marijuana was found in the trunk of the vehicle. The vehicle belonged to the driver and I was in the back seat. The driver and a passenger then proceeded to claim the weed was mine, which I strongly denied. I do have a drug conviction over 6 years ago which I repaid my debt to society, but my question is how can the sherrifs office issue a search warrant of my residence based off of a simple statement from other drug users? and my residence was the only place searched by the police even though I was the only one in the vehicle without drugs of any kind.
