OAKLAND, CA — Andres Bejarano, a former Berkeley homicide detective, testified in the ongoing murder trial of Will Watson, 29, Monday at the Rene C. Davidson Courthouse / Alameda County Superior Court.
In 2016, Watson allegedly shot and killed 19-year-old Gregory Ignacio, Jr., in Berkeley. His charges include murder, great bodily injury and the use and discharge of a firearm while committing a felony, according to his arrest record.
Bejarano, who is now a patrol sergeant for Alameda County Sheriff’s Department, testified about his analysis of Watson’s call detail record data. The court approved Bejarano as an expert witness, given his training and experience with CellHawk, a program software used to interpret and analyze the data.
Bejarano explained that a call detail record is a historical record of the device’s use that gives information such as length of phone calls and the device’s approximate location when connected to a cell tower while calling or texting.
