Progress has been made, but no arrests yet.

Kennewick police report Tuesday they served search warrants in connection with two potential suspects in the recent rash of burglaries that have seen over 35 commercial and some residential burglaries occur in the city.

According to Sgt. Ken Lattin:

'Yesterday, detectives were able to serve one search warrant on a recovered stolen trailer. The property located inside was property that was originally in the trailer when it was stolen and belongs to the owner of the trailer. We do have two suspects in this case and charges are being reviewed regarding this stolen trailer. This does not appear to be related to the pending burglaries at this time."

Police are also reviewing and renewing their investigation of a suspect they described as a "black male driving a black Cadillac" in connection with a string of summer residential break ins.  A DNA hit was received from evidence at one of the burglaries and the case is being sent to the Prosecuting Attorney for review of burglary charges.

Police say they are investigating several suspects, but do not have enough evidence to file charges.  They now say they believe the residential burglaries and the recent string of commercial break ins are NOT being committed by the same person or group of persons.

For now, it appears the rash of commercial break ins, mostly in East and East-Central Kennewick have stopped.  It could be because of the increased police presence and investigation.   While no specific details have been released, significant evidence has been gathered in these cases, and it's possible the perps are backing off for fear of being caught.

Anyone with information can anonymously report it to Tri-Cities Crime Stoppers at (509)-586-TIPS (8477).
