Forensic Psychology: Violence and Sex Crimes

Dr. LaCalle frequently participates in National and International Conferences and Seminars dealing with capital murder, violence and sex crimes.

In regard to sex and violence cases, due to the nature of his practice since the year 2000,  Dr. LaCalle only accepts cases of a notorious nature that
involve Hispanics either as perpetrators or victims. He is frequently retained
in cases involving both murder and sex ( rape, sado-masochistic practices,
ritualistic sexual abuse, molestation).

Since the early 1970s when Dr. LaCalle was asked to evaluate mentally
disordered sex offenders (MDSO), Dr. LaCalle has had the opportunity to
evaluate several hundred cases involving sex crimes, domestic violence, 
violent sex crimes, child molestation, rape, attempted murder and other violent
crimes. Over eighty percent of these cases have been with Hispanics, either
as perpetrators or as victims. 

He has been retained by the courts to do evaluations concerning issues 
such as competency to stand trial, insanity, dangerousness, amenability to
treatment, recidivism,  etc.  Cultural issues influencing Hispanic defendants
and Hispanic victims are frequently addressed in his forensic reports 
as well as in his court  testimonies.
