I could. At one point my family feared I would end up like Karen Silkwood. Ever sue anyone and won? End a business or personal relationship on a bad note? etc etc. I don't think any of them would get revenge, but I also know they wouldn't cry if I didn't wake up tomorrow. If my kid turned up missing I would name them asap.
ETA: in living life it's not hard to cross people and piss them off these days.
It shouldn't be a list of "I think this person is the type of person who would abduct a child."
I only have 2 of those people on my list.
It should be:
"This person had information about my house." (handyman, plumber, contractor. Elizabeth Smart.)
"This person showed interest in my child at the store." (Petit family.)
"This person has been trying to adopt a child who looks like mine."
"This person knew my schedule."
"This person gave me the creeps."
"That person paid too much attention to my child at our yard sale."
"This person does not like me."
I could definitely do 9.
The ex wife and her husband
My ex, his wife and any family members
My in laws (should pigs start flying and they start caring, you never know.)
Surely none of them would have done anything so stupid.
Am I sure enough to not have any of them checked out if my kid is GONE?
Absolutely not.
Then there are those who WOULD do something so stupid.
My my former friend's white supremacist husband who believes I should have aborted my oldest daughter because of her "disability."
My brother in law with the dead first wife.
My creepy uncle.
I'd be checking them out myself.
If there is a child missing... you are going to think of every possible person.
Although rarely the CORRECT person. Because you'd never suspect them... or don't "know" them.
If my niece goes missing? 9 people would just be a START.
Father, his family who hasn't been allowed to see her, stepfather's 1-3 and their kids... teachers, neighbors, co-workers, etc.
