Exercise 4

Riga and Mortis Smith are suspects in the murder of their rich aunt. They are identical twins. Tissue samples taken from under the fingernails of the aunt reveal the DNA of the murderer. The police know that Riga and Mortis are identical twins and that only one of them can be the murderer because one has a rock-solid alibi with reliable witnesses-but the witnesses do not know which twin it was.
Will the DNA testing prove who the real murderer is?
