Maybe not very likely, but still possible with in vitro fertilization. Example: Melissa Etheridge and Julie Cypher (sp?), with David Crosby being the sperm donor.
I understand, but the age of the child (a toddler?) makes me suspicious that it isn't theirs.

I also believe that is somewhere around the time Fritsh came to UofA.
Again, speculation on my part. I can hope, can't I?
