What are "halachic considerations"?

I'm sorry, I am not well-educated in these areas: IDF declares death of missing officer Hadar Goldin

The IDF spokesman announced early on Sunday morning that at 11:25 p.m. on Saturday, the Chief Rabbi of the IDF, Brigadier Gen. Rafi Peretz, declared the death of IDF officer Lt. Hadar Goldin, who fell in battle in the Gaza Strip on Friday.

The decision was made according to the findings of a special board, headed by the rabbi, who consideration medical, halachic and other relevant considerations.

There is lots of subtlety here that eludes me, sadly: IDF determines 2nd Lt. Hadar Goldin, previously considered captured in Gaza, is dead

The conclusion was based on forensic evidence from the scene of the attack,a statement by the IDF Spokesperson's Unit said. It added that prior to the decision, religious, medical and other relevant issues were taken under consideration.

I fear that behind these carefully considered, carefully presented words there is nothing but sadness.

This is how a tragic friendly fire incident is described, yes?

Please, somebody, somehow, bring these people some peace.
