Maybe. Possible disadvantage or detriment to def-EN, depending on whether state did perform GSR test or not, and whether test concluded TM had GSR or not.
Hypos:
1. LE evd tech & Med Exam'r performed NO GSR test on TM, remains released to fam
.
A. Cremated. No remains to test.
.................Result: no poss future test by St., def-EN, or future def.
................?Poss equally beneficial or detrimental to St., def-EN, or future def??? IDK.
................?Allows def: 'St skipped test that c/show TM armed & fired; def fired in self def.'
.
B. Buried Remains avail to exhume & test, by St, def-EN or future def.
................Result: Post autopsy & burial prep, test results = ?poss not meaningful? imo.
................?Poss. equally beneficial or detrimental to St., def-EN, or future def.? IDK.
................?Allows def: 'St skipped test that c/show TM armed & fired; def fired in self def.?
2. LE evd tech & Med Exam'r performed GSR test on TM, remains released to fam
.
A. Cremated. No remains for def. team testing, whether def-EN or future EN
..................If St test result shows noGSR, then Beneficial to St.,
..................Shows TM was not armed, did not shoot, so no self-defense argument for def.
..................Also shows shooter-def-EN was at least (X distance, 2-3 ft?) away from TM.
..................Also shows BM or ?* was at least (X distance, 2-3 ft?) away from TM.
..................Possible for def. team to attack ^St's witnesses & evd. by cross exam re
................. collection, swabs, chain of custody, contamination, tester expertise & interp.etc
..................Poss for def team to put on own expert witness re opinion St wit & evd. &
..................poss can refute underlying basis for St wit opinion & evd
.
..................If St test result shows GSR, shows TM was -
..........................-armed, shot own gun (benefits def for poss self-def argument for EN) or
..........................-shot by def-EN, close enough (X distance, 2-3 ft?) to leave GSR or
..........................-shot by BM or ?, close enough (X distance, 2-3 ft?) to leave GSR.
..................Possible for def. team to attack ^St's witnesses & evd. by cross exam re
................. collection, swabs, chain of custody, contamination, tester expertise & interp.etc
..................Poss for def team to put on own expert witness re opinion St wit & evd.
.
B. Buried Remains avail to exhume & test, by def-EN or future def.
................Result: Post autopsy & burial prep, test results ?poss not meaningful? imo.
................If St shows noGSR, same poss bene & detriment to St & def-EN as ^2A^.
................If St shows GSR, same poss bene & detriment to St & def-EN as ^2A^.
Could also go thru same drill re GSR testing on BM, KM, et al. Poss'ly diff adv & disadv.
I may very well be overlooking some points re adv and disadv above.
Hoping someone can fill in missing pieces.
