Johannesburg - An ex-Playboy model who is rumoured to be the girlfriend of Czech fugitive Radovan Krejcir has caught the attention of forensic investigator Paul O’Sullivan, it was reported on Tuesday.

Marissa Christopher, 35, is currently unemployed but lives in a R15m four-storey house in Linkfield Ridge and drives a fleet of luxury cars, The Star wrote.

Christopher, the estranged daughter of former Umkhonto weSizwe leader Russell Christopher, denied being romantically involved with Krejcir, who faces a range of charges, including murder.

She does state on her Facebook page that she is “in a relationship” but does not say with who. Krejcir is married with children.

O’Sullivan said he tried asking the former Playboy model where she got her wealth but she refused to speak to him.

The investigator said the house’s owner had told him to accommodate Christopher in the luxury home.

Krejcir and three others have been charged with the murder of Zimbabwean debt collector Phumlani Ncube.

He and six others have also been charged with conspiring to murder O’Sullivan and top police officer Colonel Nkosana “Killer” Ximba.
