Well let's say she is 30 pounds. That would take a strong person (possibly man) to carry 30 pounds around for a good amount of time. What if, JB did take the baby, however he was on foot, because he came back to stalk his wife, then made it to his car with the baby on foot, then went to god knows where with baby Lisa. The river? I pray not. I just know it would be hard for me to carry 30 pounds around for too long, and I know that from carrying a ten month old around every day, up and down stairs. Not to mention the four year old hanging on me, along with a Yorki Terrier who hangs on my pants leg anytime I walk through the house, LOL.
