Avery is currently serving a life sentence without the possibility of parole for the murder of Wisconsin photographer Teresa Halbach, but proclaims his innocence. The father of five was embroiled in a $36 million civil lawsuit against Manitowoc County, WI for wrongful conviction in an unrelated rape case for which he served 18 years in prison when he was arrested for Halbach’s murder. Many believe law enforcement planted evidence to frame Avery for murder in retaliation for suing – claims Kratz denies.

In the video above from Monday’s episode of Dr. Phil, Kratz tells Dr. Phil the reasons he believes Avery is guilty of murder, including luring Halbach on to his property, blood found in six different places inside her SUV, and Avery’s reported history with women.
