A forensic scientist said there was "no physical evidence" to back up former lifeguard Mark Bridger's claims that he ran over schoolgirl April Jones, a court has heard.
April, who had cerebral palsy, vanished while playing near her home in Machynlleth, mid-Wales, on October 1 last year.
Yesterday the trial of Bridger (47) heard from forensic scientist Roderick Stewart who said there was not a trace of "physical evidence" either on Bridger's Land Rover or on April's bike to back up Bridger's claim there had been a collision.
Bridger denies abduction, murder and intending to pervert the course of justice by disposing of April's body, which has never been found. He says he accidentally killed April when he ran her over and accepts that he must have got rid of her body, but cannot remember how due to memory loss caused by alcohol and panic.
The prosecution says Bridger snatched and killed April in a "sexually motivated" attack.
