1. Indications or confessions are admissible if made freely and voluntarily without coercion, threat, or inducement. The onus rests on the State to prove this beyond reasonable doubt. When an accused is found to have lied in a trial-within-a-trial, this casts doubt on their testimony unless independently corroborated, but the court must still assess all evidence to determine voluntariness. 2. Admissibility of evidence concerns procedural propriety (how evidence was obtained), while truthfulness concerns substantive weight (whether the content is credible). Admissible evidence must still be assessed for probative value. 3. A clear, unambiguous confession that directly proves the accused committed the crime constitutes direct evidence, not circumstantial evidence, as it requires no inference to connect the accused to the crime. 4. Under section 273 of the Criminal Procedure and Evidence Act, an accused may be convicted solely on their own confession provided the offence is proven to have been actually committed. 5. Intention to kill can be inferred from objective circumstances including: the weapon used, the body parts targeted, the number and nature of blows inflicted, the depth of penetration, and the accused's conduct before and after the act (per S v Mutoti). 6. Circumstantial evidence, while not providing direct proof, can establish guilt beyond reasonable doubt when facts form a tight, interlocking chain that cumulatively and logically points to the accused's guilt. 7. A murder committed with premeditation, using a lethal weapon, on an unsuspecting unarmed victim, without provocation, constitutes murder under aggravating circumstances warranting a sentence exceeding the minimum presumptive penalty of 20 years under section 47(4)(a) of the Criminal Law Code.
