Here's the information someone was asking for earlier:
"PREVIOUS THREATS OF VIOLENCE
According to court documents, the home shared by Dunn, Adkins and Hailey, had been the location of a domestic dispute back in February 2010. The affidavit says Adkins allegedly threatened to kill Billie Jean Dunn and Hailey Dunn during the dispute. Adkins initially denied that statement, but went on to confirm that he did make those statements."

In February 2010, the Colorado City police department responded to a domestic dispute at the home of Billie Jean Dunn. According to records, he threatened to kill Dunn and her daughter during the dispute.
Adkins first told investigators he never threatened Hailey, but later confirmed he did threaten the lives of the girl and her mother.
