David Sparks, who was previously named as a person of interest, and who lives at the home with his parents, was arrested on charges of abuse of a corpse and tampering with physical evidence.
After digging up the body, police also found other physical evidence linking the two: "These items were last known to be in the control of only two individuals, the missing person, and the above," Sparks' citation said, per WKYT.
Spurlock, who was 23 at the time of her disappearance, was last seen on January 4, just days after giving birth to twins. She is also mom to a two and four year old.
On the night she went missing, video surveillance showed her leaving a Lexington bar with three men, whom police believe she did not previously know, but who knew each other.
