Greek police have now raised suspicions that Caroline Crouch's pilot husband may have been a drug trafficker and killed his wife after she found out.
Theories of possible involvement in drug trafficking came to light after an investigation into Charalambos Anagnostopoulos' finances revealed that he lived in luxury despite earning a pilot's salary.
Police officers discovered that the couple had recently bought a 47 47,000 plot of land, and designed a 140 140,000 house, had also gone on some luxury trips to Dubai.
The revelation, suggests that Anagnostopoulos, 33, who is known as Babis, may have had an alternative source of income and he killed Caroline when she discovered this.
Caroline's father, David Crouch, has said he believes Babis may be involved in drug trafficking.
In the months before her death, Babis became increasingly controlling, a source said.
He allegedly installed a tracking app on her phone and accompanied her to therapy sessions.
