They called 5 times back to back when I was driving and I kept hitting ignore because I was driving.  He said he was a private investigator trying to reach my brother and his wife about an urgent time sensitive matter.  I asked what it was about and instead of answering me he started naming off family members who he has tried to call and how nobody would help out.  I asked if this was a collection call?  He said absolutely not and that he was doing an investigation that my brother supposedly asked him to start.  ??!
 He said he called his son who then blocked his number so he couldn't call back.  I asked if this was a criminal matter and he said no he is not affiliated with any police dept.  I then said I was not getting involved and he said then you are choosing to put your brother in harm's way.i hung up.
