ATHENS — Police are probing another murder case involving the Greek helicopter pilot who confessed to killing his British-Filipino wife because he said she was going to leave him and take their infant daughter.

The British newspaper The Sun said that authorities are looking into the killing of restaurateur Stavros Dogiakis, 53, shot dead some six weeks after Charalambos “Babis” Anagnostopoulos, 33, said he smothered Caroline Crouch, 20, with a pillow as their year-old daughter Lydia lay nearby.

Dogiakis' death was first ruled a uicide, but friends are asking how that is possible when he had gunshot wounds to the head and chest, the paper said. He was a neighbor of Anagnostopoulos and his wife who were clients at his restaurant, it was said.

The report added that Anagnostopoulos, who was paid 3,000 euros ($3567) monthly, spent lavishly on expensive holidays at luxury resorts and was spending big. 

Both men’s phones cell phones are being examined but the report didn't disclose any details about why Anagnostopoulos was allegedly linked to the other murder.

The paper said he has been given privileges in prison and jail sources not identified said he was sharing a cell with three men including a former guard and that he's asked for job “so he can be useful”.

"Some inmates are getting annoyed with the attention he gets. He may have to watch out,” one source allegedly told the paper, adding that police are also looking into a visit to Crete by his wife who it said looked at a villa with one of his colleagues.
