Local law enforcement had had their eye on suspect Guillermo Campos-Silva for quite some time — more than a decade, in fact. Years of investigation and hard work behind the scenes finally culminated in a raid last Friday that took down an alleged drug dealer in Harvey County. “This was a large operation,” said Harvey County Sheriff T. Walton. The raid — which resulted in the arrest of Campos-Silva — occurred at about 8 p.m. Friday, Nov. 16, in the 200 block of Southwest Second St. in Newton. The area was shut down prior to the raid. Walton said more than 80 people were involved in the operation, including units from Harvey, Reno and Sedgwick counties, as well as the Newton Police Department. An armored vehicle also was utilized. Campos-Silva currently is being housed in the Harvey County Detention Center. According to Harvey County Attorney David Yoder, he has been charged with three counts of selling methamphetamine; three counts of possession of meth without a Kansas drug tax stamp; and use of a cell phone to arrange a drug transaction. Campos-Silva is set to have a preliminary hearing at 9 a.m. Dec. 13. Walton credits Detective Nef Torres with the Newton Police Department for his persistence on the case, and for all of Torres’ work that eventually led to the raid. “Nef never gave up,” Walton said.
