Shortly after her funeral, an armed guard was temporarily hired to patrol Whitney Houston’s grave in case robbers should target the £300,000 (or $500,000) worth of jewellery she was buried with. However it seems the threat of grave-robbers is still very real as the late singer’s family have now requested security guards keep watch over Whitney’s resting place on a more permanent level. A guard was seen patrolling the site at the Fairview Cemetery in Westfield, New Jersey today. And while the hired security should fix the problem in the short-term, Whitney’s family reportedly hope to eventually have her casket encased in cement to prevent access to robbers for good. The I Will Always Love You singer, who died on February 11 aged 48, is understood to have been buried in a gold lined casket worth upwards of £10,000, and wearing a diamond brooch and earrings. The family were aware that grave-robbers could target the spot from the start, and after a huge influx of fans flocked to the site after Whitney’s February 19 funeral, the cemetery was closed to the general public. At the time, a source told The Daily Star: 'There is a very genuine fear that her coffin will be targeted by grave robbers. 'It would be hard for them to actually dig her casket up, but that won’t stop psychotic fans or people who think it could make them money. 'The fact she was buried with such valuable jewellery is just an invitation to sickos. 'It’s ironic that Whitney, who was most famous for The Bodyguard movie when she was alive, has to have bodyguards even in death.' Whitney’s mentor Clive Davis, her Bodyguard co-star Kevin Costner and friends Oprah Winfrey and Mariah Carey were among the congregation joining the family at Whitney’s send-off. The star was found dead in the bathtub of her Beverly Hills Hotel suite on February 11, with the cause of death confirmed as ‘accidental drowning’ one month later.
