About

Luis Rivera testified for the State as a cooperating codefendant after pleading guilty to second-degree murder under a 19-year sentence requiring his cooperation. He described Sigfredo Garcia recruiting him, two trips to Tallahassee, surveillance of Dan Markel, Rivera’s rental and operation of a green Prius, and Garcia shooting Markel after Rivera drove into the driveway. Rivera also described a payment arrangement involving Katherine Magbanua and cash received after the killing. Defense attorneys repeatedly examined his plea benefits, criminal exposure, prior statements, memory, and changes or disputes concerning the trips, guns, communications, and payment. Rivera maintained that investigators had not supplied Magbanua’s alleged role, denied a gang-based threat theory, and testified to limits on his knowledge of the Adelson family; at Donna Adelson’s trial, he agreed that, as far as he knew, Donna and Harvey Adelson were not involved. Prosecutors acknowledged his criminal history and inconsistencies while arguing that rental, toll, travel, communications, and other evidence corroborated material portions of his account.
