Detective: Dúvidas

Question

Good afternoon dear! I have a big question in an activity of Python3! Follow the activity link: http://www.ic.unicamp.br/~mc102/Labs/roteiro-lab06.html

First, I’ll send you my code so you can understand how I thought and how I did it (without considering the solved cases, dead people, etc)

#-* coding utf-8-*-

N=int(input())
if N<0 or N>100:
    print("Valor inválido na entrada.")
else:
    caso={}
    deceased={}
    killer={}
    xeroque={}
    for n in range(N):
        assassino,vítima,detetive=input().split()
        caso[assassino]=["assassino"]
        caso[vítima]=["vítima"]
        caso[detetive]=["detetive"]
        deceased[vítima]=["vítima"]
        killer[assassino]=["assassino"]
        xeroque[detetive]=["detetive"]
        if assassino in detetive:
            caso[assassino]=caso[detetive]
for i in sorted(caso):
    print(60*"-")

    if i==assassino:        #ASSASSINO
        if i in deceased:
            print(str(i)+" (in memoriam):"+" assassino(a).")        
        elif i in xeroque:
            print(str(i)+" :"+" detetive.")
            break
        elif i in killer:
            print(str(i)+":"+" assassino(a).")  

    elif i==vítima:     #Vítima
        if i in killer:
            print(str(i)+" (in memoriam):"+" assassino(a).")
        elif i in xeroque:
            print(str(i)+" (in memoriam):"+" detetive.")
        else:
            print(str(i)+" (in memoriam):"+" vítima inocente.")

    elif i==detetive:   # Detetive
        if i in killer:     
            print(str(i)+":"+" detetive.")
        elif i in deceased:
            print(str(i)+" (in memoriam):"+" detetive.")
        elif i in xeroque:
            print(str(i)+":"+" detetive.")

print(sorted(caso.items()))
print(killer.items())
print(deceased.items())

So far I have done this. However, right in the third test (Maria Cicero Bianca and Maria Alan Bianca) goes wrong, since the output is like this:

2 maria Cicero Bianca

maria Alan Bianca

Alan (in memoriam): innocent victim.

Bianca: detective.

---

Maria: killer(the).

I cannot understand because the program does not read the Core, since I print the dictionary of case and victims and it appears as a victim in both!
