Gabe sure is a jerk!
Spoilers...
I know that I'm not an expert and cannot say whether or not this guy killed his wife. One thing I can say, Gabe sure is rude, cocky, disrespectful... My goodness! From digging up his wife's body to move it to removing the flowers off the grave.
Even though he was proven innocent, his actions and behavior are what make him suspicious!
**Nothing is impossible, the word itself says "I'm possible"!**
