Physically of course she'd have the strength to do it.
Mentally/emotionally, I'm not so sure. She strikes me as a dependent personality, almost clingy, requiring frequent reassurance and affirmation. Reaching out to friends is expected, but there's something about how Terri has gone about this that makes me wonder how fragile her self-esteem really is. I also think if she had been the sole perp here, she would have broken already. I don't think she could stand up to the pressure knowing she would be the only one to go down for this.
IMO, if she is involved, it's either directly or indirectly with another person.
Just my gut.
'course, my gut's been wrong before
ahhhhh but if she has an accomplice (or if she is the accomplice) she has someone she can sell out......so i think it would be easier for her to crack that way
