Forensic-science-relevant second bachelor's for people who already have a BA

[1652Q]

Hello. I was hoping I could get some advice on a very niche topic. I'm a lawyer who already has a BA in a non-scientific field, and a law degree. As part of my job, I work a *lot* with forensic science experts. The overwhelming majority of these experts are in broadly medical fields: toxicology, psychology/psychiatry, blood spatter, pathology, DNA identification, etc. I'm always eager to learn more about these areas, both as personal enrichment and to improve my own job performance.

I wondered whether there are any inexpensive pathways to education in forensic sciences by distance learning. Do any of the Big Three (or anyone comparable) offer degrees that would (1) be relevant, (2) which do not require residency, and (3) which allow people to get credit for tests or programs like Straighterline, CLEP, DSST, etc.? 

If I could get a second bachelor's degree in a relevant area inexpensively via distance learning (and mostly through CLEP/DSST/Straighterline/Study.com/etc. style testing out) it might actually be worth it for me to do it. I find myself having to study a lot of this material anyway (both as part of my job and enrichment), and it would be better if I could do so systematically. Earning a degree at the end of the process would also be nice, even if it takes a while.,

Anyway, any guidance you have about programs, tests, online courses, etc. would be greatly appreciated.

Thanks!
