Judge Robert Greco has ordered Nathaniel Fujita, 18, held without bail in connection to the murder of 18-year-old Lauren Astley.
Both teens were 2011 graduates of Wayland High School. They had recently ended a three-year relationship, according to Assistant District Attorney Lisa McGovern.
Astley's body was found on a marshy area near the Wayland-Sudbury line on Monday morning. Police arrested Fujita and charged him with her murder early Tuesday morning, according to a press release from the district attorney's office.
A probable cause hearing has been set for Aug. 15.
