Yes, a person is likely to bleed if they are killed by blunt force trauma, such as being hit on the head with a baseball bat. Blunt force trauma can cause significant damage to the tissues and blood vessels in the affected area. The impact of a baseball bat to the head can lead to fractures in the skull, lacerations in the scalp, and damage to the brain, all of which can result in bleeding.
When the head is struck with significant force, the blood vessels within the scalp and brain can rupture, leading to bleeding. Additionally, if there are fractures in the skull, it can cause bleeding from the bone itself.
The severity and amount of bleeding will depend on various factors, including the force of the impact, the location of the injury, and the individual's overall health. Head injuries of this nature can be life-threatening and require immediate medical attention.
