The 45-year-old alleged girlfriend of the murder suspect is now in jail in Martinez. Authorities say she broke into the home where the murders took place and stole evidence - specifically cellphones - and then destroyed and disposed of the evidence in trash cans near where she lives in Oakland.
Sam Haldane, defending, told the court his client claims he did not wipe the device. The barrister described Mr Flanagan-Clark, a father of two from Hemel Hempstead, Hertfordshire, as a "distinguished officer" of "previous unblemished record and as I understand it the youngest detective inspector within the country". He added the defendant has worked in policing across Westminster, Kensington, Hammersmith and Fulham, Barnet, Harrow and Hackney.
