Can Someone Be Charged for Drugs Found on Another Person?

Yes, and it happens more often than people expect. Understanding how requires knowing a bit about how drug possession and constructive possession laws work.

Physical possession means the drugs were on your person. Constructive possession means the prosecution is arguing that you had control over or access to drugs even if they were not physically on you. If your fiance was present in a vehicle, a residence, or another shared space where drugs were found on someone else, prosecutors can argue constructive possession if they believe he had knowledge of the drugs and some degree of control over them.

The fact that the other person pleaded guilty and signed an affidavit claiming your fiance's innocence is meaningful, but it does not automatically end the case. Prosecutors have discretion to continue pursuing charges even when a co-defendant recants or accepts sole responsibility. They may believe the affidavit is not credible, that it was signed under pressure, or that other evidence still supports the charge against your fiance.

A few questions that matter significantly here: Was your fiance in close proximity to where the drugs were found? Did he have any prior drug-related history? Was there any other evidence connecting him to the drugs beyond presence, such as messages, fingerprints, or witness statements?

The most important thing right now is that your fiance has a defense attorney reviewing everything, including the affidavit from the co-defendant. That affidavit needs to be entered into the record formally and your fiance's attorney needs to use it aggressively. A co-defendant taking full responsibility in writing is not nothing, and a skilled defense attorney will make sure the judge or jury hears it clearly.
