mordes
"Mordes" is the genitive singular form of "Mord," meaning "of murder."
'Mordes' is used in the genitive case to indicate possession or association, showing someone being charged with the act of murder.
Der Verdächtige wurde des Mordes angeklagt.
The suspect was charged with murder.
'Mordes' here is used to specify what kind of evidence was overwhelming, again in the genitive case to modify 'Beweise'.
Die Beweise des Mordes waren überwältigend.
The evidence of the murder was overwhelming.
'Mordes' is used after the preposition 'wegen' which requires the genitive case, referring to the reason for the trial.
