A French judge has wrapped up 20 years of investigations into convicted terrorist Carlos the Jackal's possible role in four bombings in the early 1980s, a lawyer said Wednesday. Anti-terror judge Jean-Louis Bruguiere, renowned for tracking down Carlos, whose real name is Ilich Ramirez Sanchez, finished his investigations April 12, said lawyer Isabelle Coutant-Peyre. A prosecutor must now decide whether Ramirez will stand trial. The investigations center on a 1982 attack in western Paris that killed one and injured 63; a 1982 bombing on a Paris-Toulouse train that killed five and injured 77; a 1983 attack at a Marseille train station that killed 2 and injured 40; and a 1983 bombing on a train south of Lyon that killed 3 and injured 11. The suspect's lawyer now has 20 days to study the files and request more information.
