Analysis 15.The applicable law on sentencing for the offence of manslaughter is found under the provisions of Section 205 of the Penal Code which reads as follows;"Any person who commits the felony of manslaughter is liable to imprisonment for life." 16.The life sentence has been declared to be unconstitutional and it has held that an accused person may receive a sentence that could potentially allow him a chance of parole and release at some point in time; The above notwithstanding, it is the duty of this Court to impose a sentence that meets the facts and circumstances of the case; 17.The aggravating factors are the choice of weapon that had been used by the accused during the dispute over jumping the water queue; in this instance there was no evidence that the action was premeditated; the other aggravating factors are substance abuse and the lack of anger management that led to the unfortunate incident which then led to a needless loss of an precious life and all the accused was interested in was getting water for his household; despite his pre-occupation with his socio- economic stressors he ought to have exercised restraint; the mitigating factors are that the accused was a young man then aged 22 and is now aged 26 years and he is found to have no previous record and is deemed to be a first offender; last but not least is by accepting the Plea Bargain Agreement the accused had not wasted judicial time; 18.Other factors taken into consideration is the Victim Impact Assessment Report; Having perused the Report that despite the accused and his family having taken reconciliatory steps the family of the victim has not forgiven the accused and it is noted that they are yet to come to terms with their son’s demise. 19.In the light of the key aggravating factor that is the weapon of choice this Court finds that a custodial sentence be imposed to send a message and to act as a strong deterrent on the use of knives or lethal weapons being used in interpersonal disputes. that have such unfortunate consequences. 20.This court is satisfied that the accused is undeserving of leniency and or a non-custodial sentence and is instead deserving of a custodial sentence that would be a deterrent to others and finds a custodial sentence of ten (10) years to be an appropriate sentence. 21.He is found to be deserving of the benefit of proviso to Section 333(2) of the Criminal Procedure Code which section requires this court to take into account the time the offender spent in custody during the trial.
