Respectfully it is not that simple.
Look at how another police force explains how it assesses "risk level" in missing persons. It is about the person, not the circumstances:
How we assess the level of risk:
We will assess the level of risk by building up as accurate a picture of the person and their personal circumstances as possible. To do this we will take in to account such things as:
- the person’s age
- whether they need essential medication or treatment
- whether they are on the Child Protection Register.
We will also consider the circumstances of the disappearance, such as whether:
- the disappearance is out of character
- there is a suspicion of murder
- the missing person has financial, employment or relationship problems.
To report a missing person, fill in our online form or call 101. If it is an emergency and you feel that the missing person may be at risk of immediate harm, dial 999. There is no time limit on when you can report a missing person – you don’t have to wait 24 hours.
