Only 9,160 of the 38,349 missing person cases reported by police across the country in the previous five fiscal years have been solved. According to the data, the locations of 29,189 missing people have been unknown for the previous five years. This means that nearly one out of four people listed as missing is likely dead.
The number of missing persons cases has increased over the past five years. There were more than 40,000 cases reported by police in 2007. The increase can be attributed to better reporting of crime. Also, more crimes are being committed now than in past years meaning there are more opportunities for someone to go missing.
According to the FBI's Crime Statistics Report, nationwide, about 1 in 4 homicides are not solved. So it is possible that some people will always be missing no matter how much research is done into their cases.
There are several reasons why some cases do not get solved. For example, some cases may remain unsolved because the victim was known to the perpetrator and so cannot be identified publicly. In other cases, witnesses may feel too unsafe to come forward or they may be unable to identify their attacker. Underreporting also plays a role - if a crime is low-priority for law enforcement or doesn't receive enough media coverage then it won't be properly investigated.
Different countries have different rates of case resolution.
Every year, police in Australia receive over 38,000 complaints of missing people. While the majority of missing individuals are discovered within a short period of time, there are roughly 2,600 long-term missing people who have been gone for more than three months. Of these, about 170 are children.
A total of 1,611 people have disappeared without a trace from Australian cities and towns. Around four fifths of these people were men, and around one quarter were women. The average age of missing persons was 34 years old; however, there were cases involving people as young as four and as old as 76.
Almost half of all missing people were last seen in Melbourne, with Sydney following close behind at 39%. Other large cities where people tend to go missing include Perth, Adelaide, Brisbane, Hobart, Darwin and Christchurch.
Melbourne is the most dangerous city for people to go missing, with crime scene photos showing many of its missing people tied up or restrained. Others are suspected to have been killed then dumped in remote areas.
In fact, there are currently more than 100 people listed as "unaccounted for" after going missing inside Victoria's prison system. Some of these individuals have been missing for more than 10 years - many of them victims of family violence. The government has refused to release details on how many of these people are still alive.
Nowadays, the vast majority of cases reported each year are resolved; for example, as Todd Matthews of NamUs stated on NPR's All Things Considered in 2013, of the approximately 661,000 missing person cases reported in the United States in 2012, only about 2,079 remained unsolved by the end of the year. However, this was not always the case. In 1970, there were approximately 930,000 missing person cases reported in the United States. Of these, it is estimated that more than 40% remained unsolved.
The number of unsolved cases has decreased over time as technology has improved how long missing people can be expected to remain unrecovered. For example, in the early days of police work, investigators might use information from newspaper reports to try and identify suspects. If they found evidence that matched one of these suspects, he or she would likely be charged with criminal negligence if a body was recovered and evidence of violence was present, or murder otherwise. Today, computer databases allow investigators to quickly search through large numbers of suspects based on physical descriptions, photographs, and other identifying details such as tattoos or jewelry that may have been left at the scene. This can help them find suspects even if they don't know their names yet, or if they're several years removed from the incident.
As well as being dependent on technological advances, the rate at which cases are solved too depends on the nature of the crime. For example, crimes involving violence or the threat of violence have a higher likelihood of being solved.
According to recent data, the individual is discovered deceased in fewer than 1% of missing instances (0.6%), which translates to around 1,800 persons each year. According to a recent Metropolitan Police analysis, about 95 percent of these persons were adults, and three-quarters were men—the vast majority had committed suicide.
Fill out a report at your local police station. You should be aware of the police's limitations, especially if the missing individual is an adult. A person being missing is not criminal.
If the missing individual has not been discovered after 72 hours, they are normally notified, although high-risk complaints are escalated sooner. They normally get between 850 and 1,000 instances every month (5 percent of all crimes reported to police) and can give a form of profiling service to the police.
