Happy to help. Seriously tho, just toss it all. Even that little bit of blood isn’t significant. But don’t let this bag bother you too much it’s nothing to do with your dad it’s just the packaging for the meds they used plus probably some saline. You said in another comment that they were waiting for the medical examiner, which if that’s true then it would be illegal for them to remove anything that they had in place for the attempted resuscitation.
OP, sorry. Resuscitation can be chaotic and there is a chance that the bag got pushed off to the side and then they missed it cleaning up.
That does not make it okay because it looks like their BVM is in the bag, which means that was placed their after the resuscitation. Your picture doesn’t show anything aside from the little bit of blood that isn’t just garbage, so don’t worry about how to get rid of it, just throw it in the trash. But again, sorry, I’ve never personally and I haven’t worked with anyone who would intentionally leave garbage on a scene after an attempted resuscitation, it’s a small detail that someone’s family shouldn’t have to think about in this kind of situation.
I also don’t like talking to the police, even more so when I’m off duty, but I work in Florida and I’ve worked in a few counties, some after I attempted resuscitation I’d call the medical examiner’s office and tell them what’s going on and then they’d say if they wanted to come investigate or not, but currently where I work operates the same as you’re describing medical examiner comes out and investigates any death that didn’t happen under direct care of a physician.
Anyway, I’m sure you’ve got a lot going on so please toss that bag of garbage, it isn’t worth your time and effort to think about and I wish you the best in this tough time.
