In Summary
  • Ms Kamangara was killed in the house of her husband Joseph Kori Karue’s mistress, Judy Wangui Mungai.

  • She died of brain concussion, the report concluded, with the skull having been crushed by between two and seven centimetres.

  • Ms Mungai had earlier told detectives that after Mr Karue killed his wife, he gave her Sh2 million to buy her silence.

Detectives believe they are on the trail of a complex tale of money, love, blackmail and murder as they try to piece together the last moments of Mary Wambui Kamangara, the businesswoman whose lifeless body was retrieved from a dam nearly two weeks ago.

This follows the interrogation of Michael Githae Mathenge, a car-hire services operator, who on Friday led police to a thicket in Ruiru where evidence key to resolving the mysterious death of Ms Kamangara was recovered.

Ms Kamangara was killed in the house of her husband Joseph Kori Karue’s mistress, Judy Wangui Mungai, on Saturday January 26 under circumstances that are yet to be fully established.

Detectives initially went with the lead given by Ms Mungai that she and Mr Karue were at the scene of the murder. Later, detectives removed Mr Karue from the scene without exonerating him following their tracking of his phone signal and vehicle.

PRESSURE COOKER

Mr Mathenge also appeared to remove Mr Karue from the scene during interrogation in custody after he was arrested on Monday.

Basing his narration on what Ms Mungai also apparently told him, Mr Mathenge said Ms Mungai killed Ms Kamangara by hitting her on the forehead with a pressure cooker.

This is in line with post mortem findings, seen by Nation, that Ms Kamangara’s was hit with a blunt object nine times before being suffocated.

She died of brain concussion, the report concluded, with the skull having been crushed by between two and seven centimetres.

This contrasts sharply with the version Ms Wangui earlier gave the police suggesting that Mr Karue hit his wife with the butt of his gun.

Detectives are treating Mr Mathenge’s testimony with suspicion as he also sought to extricate him from blame, saying Ms Mungai blackmailed him into helping her dispose of the body from her apartment at Fourways Junction Estate.

KILLED WIFE

Ms Mungai had earlier told detectives that after Mr Karue killed his wife, he gave her Sh2 million to buy her silence.

Detectives are now grappling with which version of the events, both told by Ms Mungai to different people in different circumstances, comes close to unravelling what happened that night.

Friday, Mr Mathenge led detectives to a thicket in Ruiru where he and Ms Mungai dumped the items used to dispose of the body. The clothes used to wrap the body in and a baby seat were recovered from the scene.

Missing, however, was the pressure cooker and a carpet that Mr Mathenge told police was spread on the back seat of the deceased’s Mercedes car where the body was laid on the way to disposal. In what would be an indictment of the lax manning of road blocks, Mr Mathenge told detectives they passed a police check at Kamiti Corner and they were waved on with only insurance being checked.

SIX HOURS

According to Mr Mathenge, police said, he went to Ms Mungai’s residence at Fourways Junction at 00:07 on her invitation, almost six hours after Ms Mungai and the deceased arrived there and started arguing over the love triangle involving Mr Karue.

Ms Wambui was apparently bitter after she found her husband’s photos hanging on the wall in the house with furnishings identical to those in their family home at Safari Park Gardens Estate.
