Cats May Be Tampering With Crime Scenes, Scientists Say

Cats don't mind their own business and get their paws on anything they can.

According to a study published last month in the journal forensic science international: genetic supplement series, it turns out that they are effective for the use of genes.

70 percent of the samples were strong enough to be linked to a person of interest in a crime scene investigation, and 80 percent of the samples were found to be human genetic material.

"Collection of human DNA needs to become very important in crime scene investigations, but there is a lack of data on companion animals such as cats and dogs in their relationship to human DNA transfer," said study lead authorHeidi Monkman.

The presence and activities of the inhabitants of the household or any recent visitors to the scene can be assessed with the help of these companion animals.

There is a chance that cats and other companion pets could be carrying genetic material that could be used to solve a case.

Pets could introduce foreign DNA that could lead to an innocent person being implicated. A pet could be carrying someone else's genetic material, or it could be carrying someone else's own.

Maria Goray is an experienced crime scene investigator and expert in DNA transfer. She thinks that their findings could help clear up how pets could be involved in a crime.

Are these findings a result of a criminal activity or could they have been deposited by a pet? Goray wanted to know.

It's a question worth asking, especially since innocent people have been jailed for mistakes in the past.

The cops uploaded the image of the suspect from the DNA.
