In a case that reads like a horror movie scripted by betrayal and rage, 30-year-old Jenna Strouble allegedly turned a casual “hang out” text into a meticulously planned triple execution — first luring the father of her two young children into a deadly back-seat massage, holding a silenced Glock to the back of his head for a full eight minutes, and then driving straight to his parents’ home to gun them down too.

The chilling details come straight from Strouble’s own mouth, according to court documents and her statements to investigators after her arrest. She didn’t deny the killings. She explained them — coldly, methodically, and with a calmness that has left prosecutors and the community stunned.

It all began on the night of March 22, 2026, in the south suburbs of Chicago. Strouble, a mother of two from St. John, Indiana, texted her on-again, off-again boyfriend and co-parent Jacob Lambert, 32. She asked if he wanted to “hang out” and go for a drive. Lambert agreed. What he didn’t know was that Strouble had allegedly bought a Glock 19 fitted with a suppressor months earlier — solely for this plan.

They drove to Plum Creek Nature Preserve, but when it was closed, she pulled over on a quiet stretch of Burnham Road in Sauk Village. There, she told him she had a “surprise” for him: a back massage with a massage gun.

Lambert reclined the passenger seat, took off his shirt, and lay face-down. Strouble climbed on his back, straddling him, and began massaging for about 20 minutes. Then, according to her confession, she reached under the seat, pulled out the loaded, silenced handgun, and pressed it against the back of his head.

She held it there for eight long minutes.

During those agonizing minutes, Strouble later told deputies she wavered. She considered putting the gun down. She thought maybe she would do it another day. The weapon stayed pointed at Jacob Lambert’s skull as he lay completely vulnerable beneath her.

Then he said something.

Exactly what Jacob Lambert uttered in those final moments remains the trigger that, according to Strouble, made her squeeze the trigger instantly. One sentence — one comment — flipped the switch. She fired. The bullet tore into the back of his head at point-blank range. Jacob Lambert was dead in an instant, his body still in the reclined passenger seat of her car.

But Strouble wasn’t finished.

She allegedly drove the short distance to the home of Lambert’s parents — Patrick Forde, 55, and Stacy Forde, 54 — in Crete Township, Illinois. When Patrick opened the door, she opened fire immediately, striking him multiple times (reports indicate up to 17 shots). As Stacy came downstairs to see what was happening, Strouble continued shooting, hitting her at least three times. Both parents were killed in or near the entryway of their own home.

The triple homicide was cold, targeted, and over in minutes.

Strouble then drove back to her home in St. John, Indiana. She later handed a bag containing the loaded handgun to someone and made incriminating statements. She was arrested shortly afterward and extradited to Will County, Illinois, where she now faces nine counts of first-degree murder.

In interviews with investigators, Strouble offered little remorse and even less of a traditional motive. She complained about the way Jacob spoke to their children and described his parents as “overbearing.” When asked if she killed his parents because she didn’t want them to have custody of the kids, she reportedly replied, “That’s some of the reasons.” She also allegedly admitted considering killing her own parents because she didn’t feel her children would be safe with them.

Prosecutors paint a picture of premeditation that is almost unimaginable. Strouble bought the gun and suppressor specifically for this purpose. She lured Lambert with a friendly text. She created a vulnerable, intimate setting with a “surprise” massage. She held the gun to his head for eight full minutes — long enough to reconsider multiple times — before one sentence from him sealed his fate and triggered the rest of her plan.

The couple shared two young children, ages 3 and 4. Strouble had reportedly turned the children over to Lambert and his family at one point, only recently getting them back. Tensions over parenting and family involvement appear to have simmered beneath the surface of their on-and-off relationship.

The brutality of the crime has shocked the close-knit suburbs south of Chicago. Jacob Lambert, his mother Stacy, and stepfather Patrick were found dead during a welfare check — Lambert in the car in the driveway, his parents near the front entryway. The killings were described by authorities as targeted and isolated, with no threat to the broader public.

Strouble waived extradition and appeared in court in Will County. She faces the possibility of life in prison if convicted. Prosecutors have asked that she be held without bond, citing the calculated nature of the attacks and her own statements about considering further violence against her own family.

This case peels back the layers of a toxic co-parenting relationship that allegedly boiled over into one of the most premeditated and shocking family annihilations in recent memory. A mother of two, a Glock with a suppressor, a fake massage, eight minutes of hesitation with a gun to a man’s head — and then one sentence that ended three lives in a single night.

Neighbors and family members are left reeling. The two small children have lost their father and both paternal grandparents in one horrific evening. Questions swirl about warning signs, custody battles, and how a seemingly normal text to “hang out” could end in execution-style murder.

Jenna Strouble allegedly planned it for months. She got Jacob Lambert alone. She made him comfortable. She held death against his skull for eight excruciating minutes.

Then he said something.

And in that split second, according to her own account, the plan she had prepared for so long was carried out without further hesitation — first on him, then on the parents she allegedly didn’t want raising her children.

The suburbs of Chicago and northwest Indiana are still processing the horror. A triple murder carried out with chilling calm. A silenced gun. A back massage turned death trap. And one sentence from a doomed man that allegedly sealed the fate of an entire family.

As the case moves through the courts, the central mystery that may never be fully answered in public is simple yet devastating: What did Jacob Lambert say in those final eight minutes with a gun pressed to his head that made Jenna Strouble pull the trigger and then drive straight to his parents’ door to finish what she started?

Three people are dead. Two young children are orphaned of their father and grandparents. And a mother sits in custody facing nine counts of first-degree murder — all because, according to her, one sentence changed everything in an instant.
