'Jealous' boyfriend, 29, 'drowned a mother-of-two in a 4ins-deep pond and even answered

A 'jealous' boyfriend drowned his partner in a four-inch deep pond after flying into a rage because she was 'talking to other blokes', a court heard.

Robert McWhir, 25, allegedly forced Marissa Aldrich's face down into the shallow pool of water that runs through Loves Farm housing estare in St Neots, Cambridgeshire.

And the suspected murderer took a chilling phone call from a friend who he told 'I'm killing her, I'm killing her' as he pinned the groaning mother-of-two down, a jury heard today.

When the friend asked McWhir why he was drowning Ms Aldrich, the defendant allegedly responded 'she's talking to blokes behind my back'.

A group of his friends then rushed over and wrenched him off the oxygen-starved girlfriend and dragged her on to the bank.

An ambulance was scrambled to bring Aldrich, who had suffered a cardiac arrest and had no pulse, to Hinchingbrooke Hospital where she died on December 22.

Prosecutor Peter Gair QC told Cambridge Crown Court: 'The defendant, Robert McWhir, referred to by many witnesses you'll hear as Bobby, is accused of murdering his girlfriend.

'Drowning her in a pool of water, which flows through Loves Farm housing estate in St Neots, Cambridgeshire. It is the Crown's case.

'In the early hours, the defendant and Marissa who had been visiting friends nearby were seen to argue.

'They left alone together on foot to return to the Marissa's house.

'That route took them across a route where the pond and brook were and it was there where the defendant drowned Marissa.

'Pressed her face down into a pond containing water about 10cm deep.'

The court heard McWhir told his friends to 'get to the wooden bridge now' where they allegedly saw him holding Miss Aldrich under the water.

They wrestled him out of the way and pulled the 5ft 2 mother on to the bank, where they called 999.

A post mortem found that she died as a result of drowning.

McWhir previously pleaded not guilty to murder and today appeared in the dock at Cambridge Crown Court wearing a dark grey tracksuit.

Mr Gair told the court that Miss Aldrich and McWhir had an 'on-off relationship' and that he could be jealous.
