SALEM – Drug charges against a Lynn man were dropped Monday after a Superior Court judge determined police did not have probable cause to search his car.Celestine Martinez Reyes, 39, of 13 Johnston Ter., #1, stood charged with trafficking over 100 grams of cocaine and trafficking over 14 grams of heroin in connection with his arrest on Feb. 18.In Salem Superior Court Monday, Assistant District Attorney Michael Sheehan said he was dropping the charges against him because of a ruling by Judge Howard J. Whitehead involving a preliminary trial motionDefense lawyer Edward L. Hayden, III, challenged the legality of the search when police stopped Reyes in a 1998 Honda Accord in the High Rock section of Lynn for failing to signal on a turn.The officer became suspicious because Reyes apparently kept shaking and then observed 12 air fresheners in the car along with a heat-sealer machine and two cell phones.A search was conducted and police seized a quarter-pound of cocaine, and almost three quarters of an ounce of heroin, stashed under the console of the vehicle.Hayden argued before Whitehead that police did not have probable cause to search the vehicle, and Whitehead agreed, thus tossing out the drugs confiscated.Reyes was indicted by an Essex County grand jury in April and has been free on $1,000 cash bail since his arraignment.
