Kelsey Berreth's fiancé faces wrongful death lawsuit by her parents

The parents of Kelsey Berreth have brought a lawsuit against the man accused of her Thanksgiving Day murder in Colorado.

Patrick Frazee, 31, the father of Kelsey's one-year-old daughter, faces charges of murder and criminal solicitation for the death of Berreth’s whose body has not been found.

Cheryl Berreth, who reported her 29-year-old daughter missing Dec. 2, is suing Frazee for wrongful death along with her husband. The missing person report sparked an intensive police investigation which led to Frazee's arrest on Dec, 21 as he left his home in Florissant, Colo.
