A former Kenyan presidential candidate who killed his three-year-old son north of Brisbane in 2014, thinking he was possessed by aliens, has been sentenced to 11 years in prison.

Quincy Timberlake’s three-year-old son Sinclair died of internal injuries after sustaining severe blunt force trauma to his stomach

Crown Prosecutor Clayton Wallis said Timberlake suffered “fantastical ideations” and “delusions”

Timberlake ran to become the president of Kenya in 2010

Quincy Zuma Wambitta Timberlake had previously been charged with the murder of his son Sinclair, but the prosecution accepted a guilty plea on the lesser charge of manslaughter in Brisbane’s Supreme Court earlier this month.

However, having been in custody for more than nine years since the incident occurred, Timberlake is set to be paroled with a supervision order in place.

In sentencing, Supreme Court Justice Paul Freeburn said that late on the night Sinclair died, Timberlake and his wife Esther Timberlake, a former Kenyan television personality, heard a thud at their Kallangur home and left their bedroom to find the child at the bottom of the stairs.
