This is my hypothetical recreation of the events that happened that night.

Photos/JOSEPH KURIA and FILE Beijing Olympic Games marathon champion Samuel Wanjiru (left) of Kenya displays his gold medal on September 5, 2008. Centre: The balcony at his Nyahururu home where he apparently fell. Right: His wife Terezah Njeri is consoled by a friend outside the town mortuary on May 16, 2011.

A drunk Wanjiru went home with Nduta the barmaid. The wife came and met them at the tableroom taking some red wine. Naturally she runs berserk and becomes physical. She is easily overpowered by Wanjiru who makes it clear to her that she has to respect him since he has more than one wife and he very is capable of marrying another.
Sensing she is loosing too much ground and has no way of discussing anything with her drunk husband, she goes to the police station where she has established some close connection with a certain senior police officer who handled the earlier domestic dispute where Wanjiru had threatened her with a gun.
The police officer looking at the dejected Njeri blows a gasket, grabs a gun and rides with Njeri in her car back home. The wife gets to the gate but soon learns from the guard that there are clear instructions from the boss not to let her in. Njeri gets out of the car, reprimands the guard, gets into the compound through the smalkl gate and orders the guard to open the gate and let in her landcruiser driven by the cop friend.
Njeri walsks back to the house and finds her husband with Nduta in the master bedroom. All hell breaks loose, there is commotion, she grabs the keys and promises to expose Wanjiru and his ways to the whole world. She locks the door to the bedroom and briskly leaves the house to her car. Wanjiru has had enough, he see`s her wife leave from the balcony, jumps and lands like a cat slightly injuring his hands and knees.
He then rushes to his wife who by this time is opening the door of her landcruiser. He grabs her, shakes her up and tells her she has to give back the keys. The wifes companion aka cop friend furiously goes round the car (unseen by Wanjiru who is busy trying to wrestle the keys from his wife) and with pent up anger whips his exposed back with the butt of the gun. Wanjiru drops like a sack of potatoes. Then the cop and Njeri both realize the blow was fatal. The quickly take Wanjiru to the tableroom and try to resusctate him but its too late. The wife panics but the cop　realizing the gravity of the situation convinces the guard, a naked Nduta watching from the balcony and Njeri to carry out a quick coverup. Crucial CCTV recordings...gone, blood stains....gone....

As they say the rest is history.
