I have always wondered about revenge being a motive of some sort. If mom did not accidentally kill the child and cover it up that is.
Possible revenge scenarios:
1. The baby belongs to another bio dad. He is angry at DB for staying with JI so he takes the child as a form of revenge.
2. DB's ex husband is very angry and he hires someone to take the baby to get revenge on his ex wife.
3. A woman is angry at DB for messing with her husband so she takes the child as revenge.
4. JI's ex wife takes the baby as revenge for losing custody of her son.
5. JI is involved in something illegal or shady and his partners take revenge.
6. The ex husband of the neighbor, SB, is very angry that night to be kicked out of his home. And he drives by and sees his wife sitting and drinking with DB. He is angry and blames them for getting him kicked out of his marriage. Revenge?
Any other possible scenarios come to mind?
