I'd say he found an recent injection site on her body that she could have done herself. The outer skin would be fairly clean around that injection site if someone used a alcohol swab. Perper wants to know she was in the habit of using alcohol swabs before she injected herself.

Anyone in the medical field or anyone who injects themselves often knows that you should use a alcohol swab.

My guess is this injection site was not cleaned with a alcohol swab and Perper knows this. He also knows what was injected at the injection site as tissue in that area would have more drugs in it if the injection was recent.

Still it does not show if she injected it herself to commit suicide or if someone else did it to kill her. Plus we don't know if she used sterile methods in the past when injecting herself. Perper is using the process of elimination by finding out her habits.

Well we know Howie "isn't a doctor" but with respect to injections; they can be intramuscular or intravenous and if one is either stupid or malignant an IM injection done IV would be fatal.

Any RNs out there who could provide more information?

When there is a an injection site found this what happens...

The cell area around the injection site would be more sterile that other areas on the body.

They take skin cell scraping from around the immediate injection site, then they take skin cell scrapings from area near the injection site (from a outside an area that is at least 2" in diameter away from the injection site)

These skin cells are then examined against each other. The skin cells coming from the area right at the injection site should be more sterile if a alcohol swab was used.

Then they also take tissue and muscle samples from the area under the injection site to determine what drug was injected in to that area.

Makes sense. But won't HKS just lie depending on which way it makes it look like she injected herself? I wonder whether anyone else witnessed the injections besides ANS and HKS that could provide a history...
