The cash discovered in the couple’s bedroom, and jewellery found alongside Ms Kerr’s naked body, also raised eyebrows.
British couple Andrew Searle and Dawn Kerr appeared to be a happy expat couple living out their retirement in rural France.
Ms Kerr, 56, died after receiving “several blows to the head”, while Mr Searle, 62, died from hanging, a post mortem revealed.
On the day before the couple’s bodies were discovered, Mr Searle was seen on CCTV buying two Euro Lottery tickets and a chocolate bar.
It was also claimed Mr Searle had taken over a year to settle a bill of several thousand euros, according to local media.
