(Richmond, IN)--Police are still searching for information leading to the arrest of whoever shot and killed a Richmond teenager Wednesday. 18-year-old Caleb Stevens lived in a home with three other people on South 13th. There had been drug activity. "I don't know if we would call it a drug house or not. However, once we obtained a search warrant and entered the crime scene, there were some illegal substances recovered," said Mike Britt with the Richmond Police Department. But Caleb had no criminal record. The other two residents in the home could shed little light on what happened. "I have not been told thusfar that any demands were made. We're not exactly certain what the motive of the violence was about," Britt added. Those two, Dillan Delucio and Kelsey Boatman, were both arrested for maintaining a common nuisance.
