Puffing with exertion as he dragged his two victims' bodies down the street in a suitcase, Yostin Mosquera believed he had carried out the perfect murders.
The Colombian sadist sex worker was only rumbled on the Clifton Suspension Bridge in Bristol when a passing cyclist saw his luggage was almost bursting open with blood leaking from the seams.
Mosquera planned to throw the remains of Albert Alfonso, 62, and Paul Longworth, 71, into the gorge below Brunel's masterpiece.
But MailOnline can reveal that the police officer leading the investigation in the West Country has set out how he believes he could have 'got away with it'.
Det Insp Neil Meade has said that had Mosquera just killed the men and then booked a flight back to Colombia - he would probably be a free man today.
