Jowie, who was raised in Nakuru before he went to Dubai and later Afghanistan before returning to roam in the city, is being treated as a key suspect in the murder.

Police said witnesses placed him at the crime scene by the fact that they said he was the last person to be seen in the house.

A detective has however said they are still unable to nail Jowie because they only have circumstantial evidence.

“We are relying on circumstantial evidence for now, but we have not been successful in getting any important information from the main suspect in our custody,” the source told a local paper.

So what is circumstantial evidence?

According to lawyer John Kahuti, circumstantial evidence is evidence that relies on an inference to connect it to a conclusion of fact.

Such an inference can be as a fingerprint at the scene of crime.

Circumstantial evidence, he says, allows explanations and corroborations so that a conclusion can be drawn.

Within the criminal law, circumstantial evidence allows one to infer that a fact exists.

Kahuti says circumstantial evidence makes it hard for investigators to strongly convince the court beyond reasonable doubt that the suspect is guilty of an offence.
