This one na real toughie.
Well, if it were to be me, i wont cover him at all. If he delibrately killed the person, I will report him to the police immediately, but if i knew it was not delibrate, we'll both go to the church and pray before reporting to the police.
I will do these because, I might think it was not delibrate and it might be. If you dont report him, you might be the next person on his list.
A yoruba addage says, "pasan ta fi na iyale, o wa loke aja fun iyawo".
If you really love him, you wont cover him up, you will report him and help him find a way out (with prayer).
Although it is not easy, but one would just have to do it.
