No, this may be true of the sacrificial service, which is overridden by murder, wherefore the burial of a meth-mitzvah overrides it, as opposed to the Sabbath, which is not overridden by murder, wherefore the burial of a meth-mitzvah should not override it. And it is written (Devarim 21:23) "His body shall not remain all the day upon the tree." (i.e., On the day that you are permitted to execute him [excluding the Sabbath], you are permitted to bury him.)
