A shotgun has been discovered in the wreckage of the vehicle, along with other items that are yet to be identified.
Chief officer Patrick Rice said they had left no stone unturned in their investigation to date and appealed for anyone with relevant information to get in touch.
‘Officers have carried out a significant number of enquiries so far. We have conducted door-to-door enquiries in relevant areas, we have searched various premises connected to Mr Alps and spoken to people he was close to, including those who saw and spoke with him last.’
Rumours were shared on social media over the weekend that human remains had been found in a lock-up used by Mr Alps.
Mr Rice said there was no truth in that speculation.
There was also no concrete evidence that the remains found in the wreckage of his car belonged to Mr Alps.
‘A fire expert from the UK has visited the island to help with a further examination of the car,’ he said.
‘We have confirmed the identity markings on the car and the vehicle is registered to Mr Alps,’ although the date of registration is not known at this time.
‘While it would be very easy to draw conclusions between the confirmation that skeletal remains were present and the vehicle being registered to Mr Alps, it does not mean that such an assumption is accurate.’
