Phone records
Records from AT&T, Verizon, and other carriers document call activity and cell site location data for multiple individuals including Sigfredo Garcia, Luis Rivera, Katherine Magbanua, Charlie Adelson, and Donna Adelson. In the Magbanua retrial, both prosecution and defense opening statements addressed call detail records linking the Adelson and Magbanua phones. In the Charlie Adelson trial, the records were examined during Christopher Corbitt's cross-examination and referenced in defense opening as showing calls among Charlie Adelson, Magbanua, and Donna Adelson.
About
Phone records and cell site data were used across two trials to establish the communication pattern among alleged co-conspirators and to corroborate physical location evidence at key times in the lead-up to the murder.
