Everybody hates mosquitoes. They irritate, they bite, and they carry disease. In fact they are likely the most deadly creature on Earth since they spread malaria through many regions of the world. They also spread things like yellow fever and Zika – – – and a host of other nasty little problems.
But can mosquitoes place you at a crime scene? If so, how would this work?
Let’s say investigators come to a murder scene and find a smashed and dead mosquito on the bed sheets near the corpse. It might be reasonably assumed that this mosquito bit someone and that person then killed it, leaving it where it fell. Could that be used to ID the killer?
It appears that human blood can remain in the mosquito’s stomach for up to two days. And if this is extracted, it can be used in DNA profiling. So the mosquito at the crime scene could be collected and tested, and if DNA were found, a profile could be generated and lead back to the killer.
Esoteric, but fascinating.

I wondered if anyone has ever been convicted of a crime based on a mosquito bite. 😉

Not that I know. This technique is so new I doubt it has reached the courtroom yet.

Is it safe to say a mosquito could also place an innocent person at a crime scene?,

That would be unusually fast turnaround to test DNA in two days, right? But possible.

No that’s definitely doable. And since this was a research endeavor the turn around time would be part of the protocol.

Doug,
This is an awesome blog post. And this is just crazy enough to be totally plausible in a novel, and in real life. It seems that science and technology get better and better and crimes are being solved faster than ever before. It is an amazing thing.
Thank you for this blog post!
