Roger Berry is a murder suspect.
History[]
Berry is mildly developmentally disabled. He was falsely accused of being the Soho Strangler in 1983 by Detective John Hawkins, only to be released on parole in 2001.
Soon after his release, another series of murders began, and Hawkins was on his tail ready to take Elliot Stabler along for the ride, much to his chagrin. However, Berry was eventually exonerated after the real killer was identified. (SVU: "Redemption")
