I just recently found out. Not a huge fan but I used to listen to some of his songs.
According to TMZ, police sources said the rapper had suffered the seizure while walking through the airport and was bleeding from the mouth when paramedics arrived. Juice, real name Jarad Anthony Higgins, was still conscious when he was taken to a hospital but was pronounced dead shortly after. The cause of death is not yet known.
