A Jefferson County man faces two felony charges after Madison Police say he texted an off-duty officer about setting up a possible drug deal earlier this month.Prosecutors filed the two charges Tuesday in Jefferson Superior Court against Jason Riddle, 34, for dealing in a controlled substance.According to the probable cause affidavit, Patrolman Aaron Watson received a text message from an unfamiliar phone number while off duty on Dec. 9. The message contained information the officer believed to be about prescription medication drug activity, specifically Subutex.Watson responded to the message, setting up a time and location to meet the person sending the messages. Watson also contacted other officers about the information he was receiving, the affidavit said.Later the same day, Watson and Senior Patrolman Jacob Schmidt went to Broadway Park to meet with the person sending the messages. After exchanging more text messages, Watson was able to identify Riddle as the sender after Riddle sent information about his exact location.Officers located Riddle in a vehicle on Broadway and questioned him and another person in the vehicle about what they were doing at the park. Both men told officers they were there just to talk.When officers said they believed Riddle was at the park to sell narcotics, Riddle told them he was not and only had his prescription of Subutex with him.Officers also questioned Riddle about who he had been texting throughout the day. Riddle said he had been attempting to communicate with a friend named Aaron about selling computer parts, the affidavit said.When Watson called the number that had been sending the messages throughout the day, Riddle's phone began to ring and displayed the name "Aaron" on the phone's screen.Riddle did not have any computer parts with him at the park, the affidavit said.After separating the two men, the other person that had been in the car told officers Riddle does sell his prescription pills. The man told officers he had met Riddle at the park only to collect a debt owed to him.Riddle was arrested Dec. 9 and taken to the Jefferson County Jail.On Dec. 16, Madison Police officers became aware of additional circumstances pertaining to the case. Riddle had 8.8 grams of a controlled substance when he was arrested at the park, which enhanced one of the charges to a Level 4 felony.Riddle also was the passenger in a vehicle where a child was present. The circumstances led to Riddle also being charged with a Level 3 felony, the affidavit said.Riddle is scheduled to appear Monday in Jefferson Superior Court for an initial hearing in the case.
