Details surrounding if Wanjiru's death are still unclear, if it was a suicide or horrible accident. What is clear is the endurance community suffered a huge loss on Monday when Wanjiru lost his life after falling out of the second story window of his home in Nairobi, Kenya.
Wanjiru became the first Kenyan to win Olympic Gold in the marathon three years ago in Beijing. London Marathon race director David Bedford described Wanjiru as "the greatest male marathon runner the world has ever seen."
Regional police chief Jaspher Ombati said that Wanjiru's wife Triza had returned home early to discover her husband in bed with another woman. Reports state that she locked the two inside the bedroom and left the house. Minutes later Wanjiru was dead after falling approximately 19 feet from his balcony and hitting his head on the ground.
"It is not yet clear whether it was a suicide or if he jumped out of rage, or what caused him to fall to the ground," Ombati said.
Federico Rosa, Wanjiru's agent, told CNN on Monday, that he was "100 per cent certain" that Wanjiru had not committed suicide, saying that Wanjiru had seemed happy and relaxed when he spoke to him over the weekend.
Investigations into the exact details of his death were continuing on Monday as police interviewed Njeri and Wanjiru's female companion who was allegedly with him.
Chicago Marathon race director Carey Pinkowski said, " "I knew him as a warm, kind, fearless athlete," Pinkowski said. "I'm heartbroken."
"Sammy Wanjiru was an accomplished runner who will be remembered for winning the first Olympic gold medal for Kenya in marathon and setting a new Olympic record in the process," the International Olympic Committee said in a statement. "Our thoughts are with his family and friends."
