Attorney Benjamin Crump said he wants to bring national attention to Georgia after the death of 17-year-old Kendrick Johnson.
Crump is no stranger to the national spotlight. He represented Trayvon Martin's family and helped pushed for prosecution in that case.
A jury exonerated neighborhood watch George Zimmerman.
Crump is now representing Johnson's family.
The teen was found dead in his high school gym in January. His body was stuck upside down in a rolled-up wrestling mat.
Investigators with Lowndes County Sheriff's Office ruled his death accidental.
Today Crump joined Johnson's parents outside the Superior Courthouse in Lowndes County.
He called the death a murder and suggested calling it accidental is an insult to Johnson's family.
"It flies in the face of all common sense. So I stand here with Attorney King, proclaiming that we will solve this murder-mystery. We will get to the truth," said Crump.
In June, Johnson's parents were granted a court order to have his body exhumed for a second, independent autopsy.
"Kendrick was the light of the family. They didn't give my son any justice," said Kenneth Johnson.
Kenneth Johnson said he and his wife were horrified to learn their son's internal organs had been removed and his body was stuffed with newspapers.
"We have been let down again and when we buried Kendrick, we thought we were burying Kendrick, not half of Kendrick," said Johnson.
