Question

Criminal Investigations

Discuss the issues (if there is any) that would confront a homicide investigator in the following cases:

1. A male, aged 20 to 40, has been found in an alley in the bar area of town. There is no obvious cause of death. The body was found when a janitor came out of a bar at approximately 4:00 a.m. When the officers arrived at the scene they checked for signs of life and canceled the ambulance. At that time, according to the responding officer, the body was warm to the touch, about 90 degrees. Based on what appear to be scuff marks, it is possible that the body was dragged into the alley.

2. A female, aged approximately 15 to 25, has been found in a fraternity bedroom. The victim is lying on her side on the bed. The responding officers have learned that the fraternity had a party the night before and that she was one of the students at the party. The bedroom is a mess, but this might or might not indicate a struggle, as other rooms in the same hallway are also disordered. However, some of the bed covers are on the floor, which may indicate that something out of the ordinary went on. There is no visible blood in the room.

Answer 1

1. in first case,

It's possible that if a person is running and dies suddenly—blood circulation stops—the heat in their muscles would have nowhere to go and the body would heat up temporarily, says Noble. Or perhaps drugs that manipulate blood flow could play a role. But decompositional bacteria probably couldn't cause post-mortem heating, he says, because "the immune system is still functional at 24 hours postmortem and bacterial growth is generally suppressed."

The bacteria in our guts may continue to break down food after we die, which could generate some heat. And the cells in your body don't all stop metabolizing at once. They'll continue to use oxygen and break down food for as long as they can—which is maybe a few minutes after breathing and circulation stops. As the carbon dioxide they produce builds up with nowhere to go, the resulting acid starts to break down the cells in a process called autolysis, or self-digestion. That process could also theoretically generate heat.

2. in second case

it's possible in party they got drunked and some reasons they engaged in a fight and tha's the cause of the death without any blood marks
