FRANKLIN TOWNSHIP, NJ – A tragic series of shootings left a veterinarian, her new boyfriend, and a state trooper dead in Somerset County this weekend, authorities said, in what investigators are describing as a targeted double murder-suicide stemming from a troubled breakup.
Dr. Lauren Semanchik, 33, a veterinarian at Long Valley Animal Hospital, and her boyfriend, Tyler Webb, 29, a volunteer firefighter and mechanic, were found shot to death outside Semanchik’s home in Franklin Township on Saturday. Investigators identified New Jersey State Trooper Sgt. 1st Class Ricardo Santos, 39, as the suspect, later locating him dead from an apparent self-inflicted gunshot wound in Piscataway, about seven miles away.
Law enforcement officials said Santos’ death effectively closes the legal case but noted the reverberations will be felt in the community. They emphasized ongoing support for victims’ families and pledged to continue efforts aimed at preventing similar acts of violence.
According to details released by the prosecutor’s office, Semanchik and Santos had ended their relationship in September 2024. After the breakup, Semanchik reported ongoing harassment and controlling behavior from Santos, prompting authorities to consider his involvement when the homicides were discovered.
Police first responded to Semanchik’s residence Saturday afternoon after neighbors reported hearing gunshots and screams the previous night. Officers arriving at the scene found both Semanchik and Webb dead in the driveway from gunshot wounds. The vehicle of one of the victims was equipped with a security camera, offering investigators crucial footage for their investigation.
Reviewing the video, detectives observed Semanchik leaving work on August 1, trailed closely by a white Mercedes SUV. The footage showed the same SUV following her to her home. Later, a figure was seen moving covertly through the woods near the property. Webb, who was arriving after Semanchik, was also caught on the recording pulling into the driveway shortly before the violence unfolded.
Authorities searching for Santos found him dead inside a white Mercedes SUV at a nearby park, next to what appeared to be a semiautomatic handgun. His death was ruled a suicide by county officials. Prosecutors said the evidence, combined with the timeline and video documentation, left little doubt about the sequence of events.
Neighbors reported hearing multiple gunshots and terrified screams on the night of the killing, but said initial police response was delayed, with officers not arriving until nearly 12 hours later. The sounds described by neighbors were later confirmed by investigators as consistent with the use of a pistol.
Semanchik was remembered by friends and family as a devoted animal lover whose compassion began in childhood. She was known for her tireless efforts rescuing animals and her kindhearted nature. Those who knew her say she made a lasting impact through her veterinary work and generosity.
Webb, a member of the Pinewald Pioneer Fire Company, was recalled fondly for his commitment to helping others, both through his profession and as a volunteer firefighter. Friends described him as someone who found joy in simple pleasures, whether working on vehicles, spending time outdoors, or traveling with his dog.
As the investigation concludes, the families of both victims are receiving support from the community, with fundraising efforts underway to assist them during this difficult time.
Authorities urged anyone experiencing stalking or harassment to seek assistance, reminding the public of resources available for domestic violence survivors. The tragic deaths have underscored the dangers posed by intimate partner violence, prompting calls for greater awareness and preventive measures.
