The case against Andy B. Frye, 1608 Seaver Road, is currently pending in Sullivan County Criminal Court. Kingsport Police Det. Chris Tincher said evidence was presented to the grand jury last month.
According to a press release from police, the vandalism was reported on April 19 on the Meadowview Parkway I-26 overpass. Some of the graffiti referenced Obama as, "the modern Hitler," while other beams on the underpass read "all blacks must die" and "KKK."
Photos of the graffiti are posted on the website for the Douglass Alumni Association, a community group based in the Riverview community of Kingsport.
Det. Tincher said Frye was developed as a suspect following a piece on the vandalism that was aired by WCYB. Anonymous tipsters then contacted Kingsport Police and implicated Frye.
Frye has not admitted to being the culprit, Tincher said. He added that the tipsters said Frye had also posted racist and anti-Obama comments on the Internet, but authorities were unable to verify those claims.
Police say the Tennessee Department of Transportation spent nearly $1,000 paint over the graffiti.
