A man charged with fraud and conning a land buyer of Sh100 million was shot 13 times by gunmen along Limuru road on Thursday morning.
Paul Kariuki Ngugi was shot dead as he drove home with a female passenger.
The woman, whose relationship with the deceased is yet to established, escaped unhurt.
Gigiri CID chief Philip Kandie said police have opened investigations into the murder.
Nothing was stolen from Ngugi's car in which police found copies of title deeds and other land transaction documents.
Ngugi was charged at a Nairobi court in 2014 with conning Joseph Muthama Macharia of the money by pretending he was capable of selling a plot he did not own.
The prosecution said he forged title deeds and purported to be the owner of a Nairobi plot valued at Sh100 million.
He was accused of attempting to defraud the rightful owner of the property, in a scheme that allegedly involved accomplices not before the court.
Ngugi denied the charge of forging the title deed with the intention of defrauding Macharia.
He faced a second count of forgery, stating that the deed was signed by a registrar of titles identified in the charge sheet as F I Lubullela.
The case had been set for hearing on March 26.
