UNC Silent Sam vandalized pic.twitter.com/lhFLysVsTP — Josh Lockhart (@codeguy) July 5, 2015

CHAPEL HILL, N.C. (WTVD) -- Police are investigating after someone spray-painted the words "murderer" and "black lives matter" on the "Silent Sam" Confederate memorial on the campus of UNC Chapel Hill.The statue has frequently been a source of controversy and the scene of protests over the years."As an African-American woman, who is a student here, that statue is the very statue that pretty much says I don't belong here, that I shouldn't be here," said UNC student, Kirsten Adams. "It is a relevant statue, and so it should be there, on the other hand if we keep Silent Sam up, if we keep all these halls named after these racists, it's like we're celebrating the racism so you kind of have to draw a line somewhere.""The artist responsible for this thing we like to call vandalism I think what they've done is not vandalism, they've made a major improvement to the statue," said UNC student, Nikhil Umesh.The statue of a Confederate Army soldier was erected on campus in 1913 as a memorial to the more than 300 UNC students who died in the Civil War.Sculptor John Wilson intended the soldier to be "silent" because there is not a cartridge box on the man's belt so he cannot fire his gun - hence the "Silent Sam" name."To go out and deface that, that's been here however long it's been here, that's crazy," said James Elder, one of many who stopped by to see what happened to the statue overnight."(The statue) represents hate, represents slavery, represents the division between blacks and whites and it's not, UNC, we've gone through a lot of stuff, but that's in the past, leave it in the past, that's history," said Elder."I think it's a cowardly act done by people who skulk around in the dark of night who are not willing to protest visibly," said Chapel Hill resident James Ward.In December, 2014, someone put a plastic hood over the statue's head and left a length of rope at its feet.The overnight vandalism came as no surprise to the local chapter of the Sons of the Confederacy. One of its members told Eyewitness News he was actually keeping watch over the statue until about 11:00 p.m. Saturday night, expecting someone would do something to it on the July 4th holiday.Rick White, UNC's Associate Vice Chancellor of Communications and Public Affairs, released the following statement to ABC11:Earlier this month, a Confederate memorial in Durham's Maplewood Cemetery was vandalized.Someone spray-painted "Black lives matter" on the granite marker on West Chapel Hill Street near Duke University.The words "Tear it down" were spray-painted on the other side.
