Klink mentioned the guy was still alive in PM, so I am moving forward with that assumption.

Using one rating 6 stim patch, so I can ignore the wound modifiers
Then casting Mind Probe on the man
Since he's unconscious Pusher will need 3 hits to find anything useful, and probably no more than that.
I'll have him cast at force 3, to reduce drain, since the stim patch will add another stun in a while
Spellcasting 5 + Magic 5 = 10 dice
10d6.hits(5) = 1 hit
Drain is 3S, resisted with 11 dice
11d6.hits(5) = 3 hits, so no drain

1 hit will probably be resisted, and even if it isn't, it would only get conscious surface thoughts (which are nothing if he's unconscious).

If he doesn't bleed out in that 1 round, I'll try again
Multiple mind probes get a -2 penalty for each previous attempt, so I'll only try once more
Spellcasting 5 + Magic 5 = 10 dice
8d6.hits(5) = 5 hits (but can only get 3 hits since it was at force 3)
Drain is 3S, resisted with 11 dice
11d6.hits(5) = 4 hits

So, if there is time (6 seconds rather than 3), the ganger needs to resist (willpower + counterspelling) and if Pusher has 3 net hits afterwards (which is only possible if the ganger gets 0 hits... I was an idiot for picking force 3) then he can get the answer to one question a round for as long as he sustains the spell... which will also be limited to when the guy bleeds out (probably his body in combat turns, minus the two rounds it took his spell to stick)

Knowledge DocWagon procedures first to help in diagnosis of "patient":

DocWagon Procedures 3 + Logic 3 = 6 dice ==> 6d6.hits(5) → [4,3,5,3,2,3] = (1)

Not sure if you allow hits on Knowledge Skills to add to Active Skill dice rolls; for now assuming 'YES' and have added 1 die, remove from end of Dice Roll if you do not agree with this.

First Aid 3 + Logic 3 + Medkit 6 + DocWagon Proc 1 = 13 dice
13d6.hits(5) → [5,6,2,6,4,2,3,1,1,2,6,3,2] = (4)

So hopefully he is stabilized and maybe cured a little.
