The Salinas murder suspect, who was mistakenly released from jail last week, has turned himself in. 35-year-old Antonio Miranda Martinez reportedly walked into the Monterey County Sheriff’s Office in Salinas around 3 p.m. today and said, “Here I am.” Martinez is responsible for fatally shooting Juan Carlos Pedraza back in March. This is the second time that the Monterey County Jail has released an inmate due to a paperwork mistake.
