Twenty-year-old Alex Lee Baker of Clarksville was charged with making the calls Sunday during a 35-minute stretch.
The first caller claimed to be a witness to a murder. The second claimed he had been stabbed, while the third said a woman had been killed and buried.
Police said Monday that all the calls originated from a phone owned by Baker, who remained jailed on $15,000 bond. A spokesman said Baker had not retained a lawyer.
