Mbombela - Her third husband was supposed to have died in a "hijacking", but instead, Maria (Marietjie) Ferreira is to spend seven years behind bars for the "murder" she tried to stage.Ferreira, 53, pleaded guilty in the Regional Court in Mbombela on Wednesday to conspiracy to commit murder, Netwerk24 reported.In terms of a plea deal with the State, she will serve seven years of a 12 year sentence which has been suspended for five years."I'm just glad that the case was wrapped up so quickly and that we could save the guy's life," said the Hawks' Colonel Danie Hall, who arrested Ferreira."She [Ferreira] was sentenced about four months after her arrest and I hope this is sending a clear message that crimes such as this won't be tolerated."Hall said Ferreira would have to serve her full sentence should she be found guilty of any violent crime, including assault, after her release. He arrested Ferreira at a filling station in White River after she promised a man R20 000 to kill her husband, 55-year-old Carlos Ferreira. However, the "assassin" turned out to be a member of the Hawks.Hall said the couple had visited friends in White River on the weekend of March 19. Ferreira apparently wanted her husband killed during a "hijacking" on their way to Mozambique. The couple managed the Primo Cabanas Lodge in Mozambique."Her husband was very surprised when we informed him of her alleged plans," Hall said.Ferreira's first husband died of cancer.Her second husband, Alan Hepburn, was 42 when he was stabbed to death on February 5, 2012, on a smallholding in Bronkhorstspruit while changing a tyre.No one has been arrested for his murder.
