jury duty guilt

I was on jury service recently and we had a case about rape and wounding with intent. The details of the case made it hard for evidence to be gathered in general. However, in this particular case, the police and prosecution did not do enough to gather enough evidence to convict the defendant. There were many damning gaps in their investigations which could’ve changed the verdict, i.e. if they had just followed up on a signature to test substances left behind in the crime scene. The fact that the victim did not show up in court and was unreliable also made it harder to believe their side of things.

A lot of us thought he was guilty but could not prove it and as a result the jury returned a majority not guilty verdict and the case finished.

We were able to research details and I probably shouldn’t have but I found out the defendant had committed sexual assault before and now I feel so guilty for not being able to convict this felon even though the evidence was not adding up. I know I should direct my anger towards the police’s negligence and the prosecution however I can’t help but feel guilty for having a role in this man being set free. Now I’ve been getting horrible migraines and don’t know what to do about this horrible feeling.
