What aspect of an assault case increases its severity?

The severity of an assault case is significantly increased by the use of a weapon. When a weapon is involved, it typically elevates the potential for serious injury or fatality, thus enhancing the overall dangerousness of the situation. This aspect not only reflects the level of threat posed to the victim but also often leads to more severe charges under the law, such as aggravated assault, which carries heavier penalties compared to simple assault. The presence of a weapon implies a greater intent to cause harm, which courts recognize as a critical factor in determining the seriousness of the offense.

While the other choices may contribute to the overall context of the case, they do not directly correlate to the intrinsic severity of the assault itself as the use of a weapon does. Witnesses can provide information but do not inherently change the nature of the assault. The value of stolen property relates more to theft than to assault, and while the age of the victim can influence charges in some situations, it is the use of a weapon that fundamentally alters the landscape of the assault in terms of legal repercussions.
