In the aftermath of the three deaths, it has been reveled that Semanchik had tried for months to escape Santos’ obsessive control, whereas multiple institutions, including law enforcement, failed to act.
Semanchik and Santos had only dated for three months in 2024, before she ended the relationship after a few months. 
While that relationship ended after three months in September 2024, what followed, according to her family and police records, was a year-long campaign of stalking, sabotage, and harassment. 
Prior to the murder Semanchik accused Santos of harassing her and controlling behavior, investigators said.
‘He showed up at her work. That’s where the car was keyed. He put recording devices in her home, water in her gas tank. He harassed her left and right,’ her sister said. 
When Semanchik had tried to block his calls, Santos resorted to using restricted numbers.

Dr. Lauren Semanchik was employed at the veterinarian at Long Valley Animal Hospital in Long Valley. She was known for her love for the animals and good natured attitude towards owners

The victim’s mother Jeannine Semanchik said her daughter tried several times to get restraining orders, but none was issued.
‘A lot of agencies failed her. She tried to get restraining orders. Nobody called her back.’ 
Semanchik then tried contacting her stalker’s colleagues for help, albeit with no relief. The abuse continued.  
The final dastardly move by Santos was captured in detail on footage from a surveillance camera Semanchik had installed in her car in the face of the relentless stalking.
The security footage recorded on Friday, August 1, shows her car leaving her business address at Long Valley Animal Hospital, around 5:25pm, when a white 2008 Mercedes SUV, pulls out right behind her, tailing her for 30 miles to her home.
