Now he is a very unstable man, whose word and opinions cannot be taken seriously, as they are more than likely products of paranoid delusions. As well as being the profiling mentor to Goren, his studies were once considered very reliable and respected among his colleagues, but a mental breakdown changed all of that. Goren is the only person who puts any stock in his opinions.
He mistreated his own daughter, because he wished he could have had a son, which he saw in Goren. This turned her into a serial killer, and she murdered three people in order to just get his attention. When she was exposed, he was only happy that he had helped in the catching of a serial killer. This led to a breakup with Goren.
He later teams up with Nicole Wallace to kill Frank Goren and later kills her to free Goren of the three people in Goren's life he viewed as poison, including himself. Jo Gage's refusal to ever see him again was the trigger of this. He frames Goren for the murders to make him fight back and even sets himself up as one of Nicole's victims to help sell the story. He is eventually exposed and arrested for the murders.
He was tried and convicted of all murder charges against him (including Nicole's) and was sentenced to life imprisonment without parole in maximum security.
