On the morning of the murders Jeremy Bamber telephoned his girlfriend Julie Mugford at around 3am. The timing of this call was the subject of much investigation and was attested to by Julie and two of her flatmates.
According to Julie, Jeremy told her on the telephone that his father had telephoned him to say that his sister had the gun and that he was to phone the police. Julie said that she told him to go back to bed.
We also know that Jeremy did telephone the Essex Police control room at Chelmsford some time later at approx 3.26am and reported the same telephone call from his father.
During his interview shortly after the murders Jeremy mixed up the timings of the telephone calls.
And in 2003 he claimed that, "I did not speak to Julie prior to speaking to the police, but spoke to her after I had spoken to them. The principle reason I spoke to her was because I was concerned about phoning the police and getting them involved in a private family matter."
