From our CEO, Danny Hellwig:
For more than 15 years, the murder of Theresa Morlock has been part of my professional life.
I worked on this case during my time at Sorenson Forensics, Intermountain Forensics, and now Resolve Forensics. Through multiple laboratories, changing technologies, and many years without an answer, the case never went away.
Last week, James Petersen pleaded guilty to Theresa’s 1993 murder after DNA evidence and investigative genetic genealogy helped investigators finally identify him.
It is difficult to describe how much joy and relief I feel seeing this case resolved after 33 years. Cases like Theresa’s are why so many of us stay committed to this work, even when the answers take days, weeks, years..or decades..to arrive.
I am deeply grateful to the Salt Lake City Police Department investigators including the absolute bulldog, Cordon Parks who never let this investigation go and the forensic scientists and genealogists at Intermountain Forensics, the prosecutors, and everyone else who continued pushing this case forward.
Most importantly, I hope this guilty plea brings some measure of justice and peace to Theresa’s family and everyone who loved her.
Theresa was not forgotten. Not for one single moment!
-Danny
