He lived by the gun and died by the gun. This phrase best describes Daniel Gucoma who was sprayed with bullets by unknown assailants at Gwa Kairu, Ruiru along Thika Road on Tuesday, June 22.
According to detectives probing the murder, Gucoma was dangerous criminal who had been involved in multiple acts of crime together with his wife. Apparently, he was the leader of a gang that has been terrorizing businessmen in Nairobi and was involved in a series of crimes.
His wife, Susan Wangari who days earlier had narrated how a matatu ride saved her life, was his most prominent accomplice. Gucoma had also been charged with robbery with violence together with his mother Mary Wanjiku Nditure and his wife Susan Wangare Njoroge in 2015.
Wangari had been arrested in 2014 after allegedly carjacking a motorist at gunpoint in Nairobi. In 2017, she faked police credentials and imposed herself as a policewoman. She was accused of assaulting and carjacking a businessman on the highway at night.
The trader said that Wangari, in the company of another man, was armed with a pistol. She was tracked and arrested and was charged with robbery with violence. She pleaded not guilty and was released on a Sh. 500,000 bond.  Last year, Wangari and Gucoma were once again accused of robbery with violence.
