😢 Police Revealed What Happened After A Florida Mother Discovered P*** On Her Husband’s Phone—A Tragedy That Left A Grandmother, Two Little Girls And A Family Shattered
Florida Mother Shot Grandmother and Two Young Daughters After Argument Over Husband’s Porn, Police Reveal in Chilling Murder-Suicide Update
A quiet Florida neighborhood was shattered in the early hours of May 3 when a mother carried out a devastating killing spree that left four people dead, including a four-month-old baby and a four-year-old child. Months later, Plant City police have confirmed the unthinkable: Hailey Dempsey, 27, shot and killed her own mother before turning the gun on two of her three daughters and then herself.
Police Chief Richard Mills Jr. delivered the grim update on Thursday, closing a complex three-month investigation that stretched across two crime scenes, hundreds of pieces of evidence, surveillance footage, digital records, and multiple interviews. The chief’s voice cracked as he described the scene as the worst he had encountered in 34 years of law enforcement.
According to investigators, the violence began inside the family’s home on North Burton Street. In the early morning hours, Hailey shot and killed her 55-year-old mother, Valerie DeBoe. She then gathered her three young daughters and left the house on foot. Security cameras captured her walking through the neighborhood around 5:35 a.m. At one point she approached a nearby residence and asked for help. The children could be seen crying. When the resident stepped away to get a partner, Hailey and the girls had already vanished.
She continued walking until she reached a front yard on West Tever Street. There, around 6:57 a.m., she concealed herself and the children behind bushes and trees. She fatally shot her four-year-old daughter and her four-month-old baby. She also fired at her two-year-old daughter but missed. Then she turned the gun on herself.
Police received a 911 call reporting screams and arrived approximately 50 minutes later. The surviving toddler had been alone at the scene for nearly an hour. Officers found the two-year-old crying and covered in blood, though she had no physical injuries. Hailey was still alive when first responders reached her but later died at a hospital. A 9mm Glock was recovered near her body. Forensic testing confirmed gunshot residue on her hand.
The surviving child, identified in family statements as K.D., spent time in foster care under state protection before being reunited with relatives. An attorney for the Dempsey family said the little girl is now “vibrant and full of life,” and expressed deep gratitude to the foster family who cared for her during the difficult months.
Investigators ruled Hailey’s husband, Jay Dempsey, out as a suspect after a thorough examination of his whereabouts and actions. He had been staying at a friend’s house in Lakeland at the time of the shootings and cooperated fully with police. Jay was detained briefly while officers executed a search warrant but was never charged.
In the days leading up to the killings, tension had been building in the household. Police responded to the Dempsey home three times between May 1 and May 2 for verbal arguments. Chief Mills said the disputes centered on pornography Hailey had allegedly found on her husband’s phone and concerns about possible infidelity. The family held strong religious beliefs, and the discovery had created significant strain.
“There was no indication whatsoever of anything criminal, no violence involved, it was just an argument,” Mills explained. “It was in fact surrounding some infidelity and some porn that she allegedly found on one of his cell phones. They do have religious beliefs in the family, so they were going through some issues related to the porn. I think that’s where everything stemmed from.”
On May 1, Hailey gathered her belongings and left with her mother and children. She later called police because she believed a tracker had been placed on her car. Officers found none. That night the group stayed in a hotel. The following day Hailey asked police to stand by while she returned to the house to collect more items. She also met Jay for a private conversation at a library.
Neighbors reported seeing Jay wearing a bulletproof vest and loading a duffel bag into a vehicle the night before the shootings. Mills addressed the sighting directly. Jay is a gun owner with several legal firearms. After police visits, he became convinced authorities or the ATF might return and confiscate his weapons. He gathered the guns and a vest and took them to a friend’s house for safekeeping. No criminal activity was found in connection with those actions.
Valerie DeBoe was remembered by family as a devoted wife of 30 years, mother, grandmother, mentor, and leader. A GoFundMe created in her memory described her special joy in her role as “Gigi” to her three grandchildren. She is survived by her husband and two sons.
Chief Mills emphasized that the investigation was deliberately slow and careful. Releasing information too early, he said, could have compromised witness statements and the integrity of the case. Hundreds of pieces of evidence were processed. Multiple agencies assisted. Digital evidence suggested possible indications of mental illness, but officials declined to release further details about motive.
“This is a tragedy that has deeply affected two families, our community, and the men and women of the Plant City Police Department,” Mills said. He noted that a regional critical incident management team was brought in to support officers and firefighters who responded to the scene.
The surviving two-year-old’s recovery has offered the only measure of hope amid the horror. Family statements describe her as thriving after months of careful care. Yet the loss of three generations in a single morning continues to weigh heavily on everyone connected to the case.
What began as marital arguments over private material found on a phone ended in one of the most devastating scenes local law enforcement had ever encountered. A mother, a grandmother, a four-year-old, and a four-month-old infant are gone. A toddler who somehow survived the gunfire now carries the weight of a story no child should ever know. And a quiet Florida neighborhood is left trying to understand how such darkness could unfold so completely in the space of a single morning.
