the detectives who coerced eddie lowery into falsely confessing, douglas johnson and harry malugani, rom law enforcement. in depositions for the civil suit, doug johnson suggested perhaps eddie lowery was still involved with the rape. >> he was so defiant still at that time that he put the right person in prison that he started -- he made up an excuse how i could have been there. >> i still believe it's possible that he may have been at the scene or that he may have -- >> patrick caffey, the prosecutor who convicted lowery, made a similar statement during msnbc's interview with him. >> maybe he did know something about the crime. i don't know. i don't know that. >> how would he know anything about the crime? >> well, you're asking me for speculation -- pure speculation here, but perhaps he was with the rapist. i don't know. >> barry scheck reacted strongly when told of the former prosecutor's statement. >> you're telling me that eddie lowery gave a false confession that he and he alone committed this crime and protected brewer, a serial rapist who was raping other people in the neighb
