Cape Town -

A couple accused of killing a policeman and burying his body in their backyard appeared in the Western Cape High Court on Friday.

Barnabas Sentiwe and his wife Phumza Veli were dressed casually and seemed sullen as their pre-trial conference was called up.

The court heard the defence team had been given further particulars, but had not yet consulted with the pair.

The matter was postponed until next Friday.

The couple had been the neighbours of 29-year-old Constable Monwabisi Mnyombolo in Extension 6, Mfuleni, Cape Town.

It is the State's case that Sentiwe got into an argument with Mnyombolo at the couple's house in October 2009, accusing him of having an affair with his wife.

Sentiwe allegedly stabbed the police officer.

In 2010, he sold his house to Moses Njovana.

Njovana's wife saw a pair of tracksuit pants in the ground next to the house in 2011 and when he dug them up found bones inside.

Police were called to the scene and a shallow grave with more human bones was unearthed.

Forensic testing revealed the bones belonged to the constable and a post-mortem revealed he was stabbed in the head.

The State has charged Sentiwe with murder and his wife as an accessory after the fact. - Sapa
