A Jackson County man faces charges that he provided alcohol to a Dickson County teenager that ultimately contributed to her death. 26-year-old Dustin Dwayne Bartlett of Union Street in Gainsboro was indicted by the Dickson County grand jury last month on two misdemeanor counts of providing alcohol to someone under 21 and one felony charge of criminally negligent homicide. The same indictment charges 31-year-old William E. Gillis of Highway 47 in Dickson with one count of providing alcohol to a person under 21. Prosecutors allege that Bartlett’s actions were “criminally negligent conduct” that were a proximate cause of the death of a 19-year-old Dickson County woman. An investigation showed the teen died July 10 at Maury Regional Medical Center in Columbia from what investigators said was a lethal mixture of alcohol and prescription medication. The first two counts of the indictment charge Bartlett while the first count includes Gillis for purchasing an alcoholic beverage for or at the request of a person under the age of 21 but do not specify to whom the alcohol was given. The 19-year-old’s death led Nashville prosecutors to dismiss seven charges of statutory rape and sexual assault by an authority figure against a former Dickson County High School teacher and coach. The Davidson County District Attorney’s office said it could not proceed with the case without the teen’s testimony about the sexual relationship she had with the teacher that led to an investigation in 2011. Bartlett was originally indicted in January on two counts of providing alcohol to an underage person but a superseding indictment adding the criminally negligent homicide charge was handed up in June. Bartlett has been in jail since his arrest Jan. 21. Bartlett and Gillis are scheduled for an arraignment in Dickson County Circuit Court July 14.
