1. (1) That the summons or rule to show cause cannot be served; or
2. (2) That the respondent has failed to obey the summons or rule to show cause; or
3. (3) That the respondent is likely to leave the jurisdiction; or
4. (4) That a summons or rule to show cause would be ineffectual; or
5. (5) That the safety of the petitioner is endangered; or
