Do we know if there was any discord in the relationship of the parents?
could they of had a fight after the party (2 days before) and baby Lisa got accidently hurt and they were to afraid to call 911 and she died?
so they told grandpa she was sick and made up all of this?
Lisa's grandfather knew she had a cold. He said she was a little fussy that day. He was there at the party with her.
