Michigan authorities on Monday launched an investigation after a racial slur targeting Trayvon Martin was discovered on an electronic construction sign along a Detroit-area interstate.
Michigan State Police told NBC News affiliate WDIV-TV that someone hacked the road sign along I-94 around 1 a.m. Monday and posted "TRAYVON A N*****".
Martin was shot to death by George Zimmerman, a neighborhood watch volunteer, at a gated community in Sanford, Fla. on Feb. 26. Zimmerman has claimed self-defense, telling police Martin attacked him. Martin was unarmed.
Motorists who saw the sign heading into Dearborn, Mich., pulled over and reported the sign to state troopers.
"I feel violated by it," Elaine Bonner told WDIV-TV.
Michigan Department of Transportation spokesperson Rob Morosi said someone broke into the sign’s operating system and put up the racial slur, changing the original message.
The message on the construction sign was taken down before Monday’s morning commute.
Michigan State Police and the Michigan Department of Transportation are investigating and have turned to the public for help in finding those responsible for the hacking.
"Whoever it is needs to be found. They changed the message, now find the messenger,"the Rev. Wendell Anthony, Detroit NAACP president, told WDIV-TV.
