The accused denied the charges.
Ng’ang’a’s lawyer Assa Nyakundi held brief for three others during the ruling – they sent apologies saying they were attending to cases in other courts.
Outside the courtroom after the judgment, Njeri’s relatives said they will appeal the ruling as they were dissatisfied.
Widower Martin Mbugua said he could not comment as he needed time to come to terms with the ruling on his wife’s death.
Mbugua’s father Peter Ndung’u said his children had been denied justice.
Ng’ang’a distanced himself from the accident that year and accused police and the media of tarnishing his name by linking him to it.
He said he is “not like [Salvation Healing Ministry Pastor Victor] Kanyari”.
“MINE IS A LEGITIMATE MINISTRY AND YOU CANNOT PULL ME DOWN,” HE SAID.
