He pleaded guilty to the offense, which he committed on the evening of 2 April last year, behind the family home’s pit toilet.
The man came home drunk that evening, between 7 and 8:30pm where he took the victim out and sexually assaulted the 7 year old, by inserting his penis in her mouth. He also fondled her genitals.
Her father found them outside, after he passed out, as he was under the influence of alcohol.
Despite the plea, the age difference was a factor the court considered when deciding his sentence.
He spent one-year, six-months and 24 days in custody prior to his sentence today.
That time period will be suspended from the jail term of 15 years.
He will serve the remaining 13 years, six-months at Bomana.
