Coverage

Coverage as a word is often used to describe how much of a search area or sector has been searched. This is wrong. Coverage has a specific mathematical definition in search theory. It refers to the Area Effectively Swept divided by the Area of the Search Sector. This figure is then used in Koopman’s Exponential [...]

Probability Density (Pden)

The probability density is found by dividing the Probability of Area (POA) by the size of the search area or sector. This gives you an idea of the likelihood that the missing person or object is in an area of the same size in two different search sectors. It is an extremely important concept to [...]

SAR Dictionary

I have decided to start an online SAR dictionary that I will add to every week. Hopefully it will help those looking for more information and/or definitions of various SAR terms. So far I have added; Probability of Area (POA) Probability of Detection (POD) and Probability of Success (POS) More will be added week on week.

Probability of Success (POS)

Probability of Success is the likelihood of finding the misper or search object given the search area and search resource. It is calculated as below; POS = POA x POD It is the role of the Search Management Team to maximise the POS of the search. [Find the missing person or object as quickly as possible!] This [...]

Probability of Detection (POD)

Probability of Detection refers to the likelihood of a search resource finding the object they are searching for if it was in the area they were searching. Thanks to Koester, Cooper, Frost and Robe’s 2004 study we can now safely say that it is impossible to subjectively estimate POD. No more should we hear supposed Search Managers [...]

This month's feature is the Missing Rights Campaign being run by Missing People.

If your house is burgled you are automatically offered emotional, practical and legal support. If your child goes missing you may get nothing.

Missing People. are calling on the Government to give families of missing people the same basic rights as victims of crime.

Over 250,000 people go missing in the UK every year. While most of us will have read or heard about a disappearance, little is understood about the emotional, legal and financial burdens it can bring to those closest to the missing person. Families left behind face their homes being seized, jobs being lost, divorce, social stigma and suicidal thoughts.

Here are the detailed aims and objectives of the Missing Rights Campaign. Without your support, though, they will not be able to bring about change for families of missing people.

Aim #1:
Families of missing people should know everything possible is being done to find their missing loved one.

Objectives:
•Every region to have a local missing persons coordinator who will hold local services to account
•Every family to have a named single point of contact in the police force dealing with their missing loved one
•All unidentified bodies to be cross matched with missing person reports

Aim #2:
Families affected by a disappearance should have access to support.

Objectives:
•Every family of a missing person to be signposted to Missing People’s free emotional, practical and legal support services by the police
•A network of specially trained counsellors to be developed to support the unique needs of families of missing people

Aim #3:
Families left behind should be spared the pain of unnecessary financial and legal bureaucracy.

Objectives:
•All banks to introduce standard mortgage arrangements for families of missing people
•All insurance companies to enable families to freeze or take over their missing relative’s policy payments.
•Presumption of Death Act to be introduced in England of Wales
