No, a homicide case cannot be concealed as electrocution with both entry and exit wounds.

There is associated finding in electrocution.

Thanks for considering my question, I had recently came across this article in which they have reported  a case of concealed homicide... have attached the article, kindly go through sir.

If electrocution injuries are postmortem, I think it is impossible to disregard the murder.

As we can see in the article attached , it is not only electrocution marks which are present in the body but also other injuries were found suggestive of homicide. By meticulous post mortem examination, we can differentiate between antemortem and post mortem injuries.It will be more challenging if the findings of homicide are nor evident and post mortem electrical injuries are present.
