I don't think there are any witnesses that Susan could bring that would make her look good.I believe the next court date is end of July. It wouldnt be surprising if Susan's lawyer asks for another continuance. Allegedly Sussn is bringing witnesses to this next hearing.
Michael AND his wife will be attending.
Michael should contact some of Jani's teachers that have had to deal with Susan. I'm sure some of them would love the opportunity to express what they've seen.
