A Paraguayan prosecutor known for his work in fighting organized crime, was killed on the Colombian tourism island of Baru, the same day as he and his wife announced she was pregnant.
Colombian authorities have said they believe the assassins arrived by jet skis to the beach where Marcelo Pecci was relaxing and killed him with three shots fired on Tuesday.
Pecci and his wife, Paraguayan journalist Claudia Aguilera were on their honeymoon at a resort near the Caribbean city of Cartagena after getting married on April 30.
