Karl Merl has been arrested on DUI manslaughter charges in Pinellas County after police received test results that show the Largo man had marijuana in his system at the time of a car accident that killed an 83-year-old pedestrian in 2008. Merl is being held on $50,000 bail in the Pinellas County jail.
The incident took place in November of 2008 near 105th Avenue and Oakhurst Road. According to witnesses Merl made no effort to avoid Kathryn Melnick. Merl’s blood sample showed there was tetrahydrocannabinol on his system. THC is a pyschoactive substance that is found in marijuana.
