The person whose body was found with multiple stab wounds on Constitution Beach yesterday morning was Wilson Martinez, 15, of East Boston, the Suffolk County District Attorney's office reports.
A passerby found Martinez's body around 8 a.m. near the yacht-club end of the beach.
Because the beach is owned by DCR, State Police are investigating the murder. Anybody with information can contact detectives at 617-727-8817.
“No piece of information is too small to be helpful,” DA Dan Conley said.
