POLICE have scaled down the search in Cornwall for Guernsey girl Frankie Chappel.

The 17-year-old was travelling in the back of a Volvo with her brother, Ryan Martel, 26, driving and two passengers in Zennor near St Ives early on Saturday.

The car plunged into a swollen stream after the road they were travelling on collapsed because of flash floods.

Front seat passenger Oliver Gardner, 20, managed to get out and raise the alarm.

The body of a 20-year-old back seat passenger, believed to be Luke Mackin, was discovered on Saturday.

A second male body, believed to be that of Mr Martel, was discovered on a nearby beach on Sunday, but police have yet to confirm his identity.

Former teachers and friends of the siblings say they have fond memories of the pair.

Ryan Martel, who was also known as Ryan Chappel and Ryan Nelson, was born in Guernsey and attended St Sampson’s Infants, Vauvert Primary and St Andrew’s Primary schools.
