(CBS 8) - This story could go into the "San Diego's Dumbest Criminals" file. A Lakeside man goes to visit his son in a Colorado prison and ends up behind bars himself on suspicion of smuggling drugs. Convicted felon Donald Curtis, 56, was arrested by FBI agents Friday at a Florence, Colo. federal lockup after plotting over a monitored phone with his imprisoned son for two months. According to an FBI agent's report, Denney planned to smuggle a golf ball-sized chunk of black tar heroin he had wrapped in plastic and hid in his rectum. Authorities say Denney was going to transfer the drugs by giving his 29-year-old son, who has the same first name, a mouth-to-mouth kiss during a visit. "I felt so disgusted and would never imagine taking something out of my butt and putting it in my mouth in the first place, but to kiss my own child?" neighbor Mike V. said.
