Munks noted that the tens of thousands of data points, which covered a weeklong period, were a larger data set than what he would typically see in an investigation. Melina Frattolin was found drowned to death in a marsh in rural New York, at the end of her trip with her father. Luciano Frattolin has pleaded not guilty to the two charges and has been held without bail since his arrest last July. Munks also testified that he analyzed data showing that shortly before she disappeared, the girl messaged her mother on her own phone to get in touch with one of her friends. In subsequent testimony, the jury heard how police tracked a silver Prius that Frattolin had rented and used for the trip.
