Missing Colorado mom Kelsey Berreth's haunting final text messages with her fiance, Patrick Frazee, have been released. “I bought some sweet potatoes in case you wanted sweet potato casserole,” read one text that was sent to Frazee. He never responded. Instead cops say he went to Berreth's home and beat her to death. He allegedly took her phone and spent the next three days sending fake texts to create the illusion that she was still alive.
