Caelan Morrison had to deal with being a teen parent while also managing his deteriorating relationship with his children's mother, McKayla Adkins, on TLC's Unexpected. The pair, who had been together since they were 14 years old, found themselves adolescent parents not once, but twice. After their first daughter was born in April 2008, they also had a son a year later. Unfortunately, the stress of being a young father was too much for Caelan, who died at age 19. His body was discovered by family members who came to visit him in prison. They believed he had taken his own life because he couldn't face another stint in jail. However, an autopsy revealed that there were signs of trauma about his body that didn't match up with how he had described his death to them. Authorities believe someone may have killed him instead. In December 2009, it was reported that Caelan's mother had been charged with murder after allegedly hitting her son in the head several times with a blunt object before putting him in the trunk of his car and driving with him all over Tennessee trying to hide his body. She was said to be very distraught over his death. It's suspected that she killed him so she could get out of paying child support for both of her sons. She was held without bail until her initial court appearance last month.
