Jennah Marie Seibert, 24, a woman from the Belle Vernon area of Rostraver Township, was discovered dead inside her home on Lenity School Road on April 11, 2025. Police and the Westmoreland County coroner identified Jennah Marie Seibert, 24, at the scene, and authorities soon classified the case as a homicide. Initial reports from the scene described a violent death and a house where the power had been cut; investigators also noted that her vehicle was missing.
The discovery rattled a typically quiet stretch of road as detectives secured search warrants and began piecing together a predawn timeline.
Jennah Marie Seibert, 24, was found after her fiancé contacted police; a search-warrant affidavit recounted his account of returning around midday and finding her in bed amid blood and a ransacked home. Investigators traced the couple’s black SUV through traffic cameras and plate readers to Monongahela, where it was recovered. Surveillance stills released by the district attorney’s office showed a mustachioed man—publicly labeled a person of interest—buying items at a convenience store that same morning as the vehicle’s movements were tracked.
Within days, county detectives publicly sought that person of interest, while local outlets documented the expanding investigation at the house and along regional roadways. Officials confirmed that Jennah Marie Seibert, 24, died of gunshot wounds and that multiple warrants were executed as the case shifted from a “suspicious death” to a homicide. Community reports described the cordoned road, the hours-long police presence, and the growing sense that what happened inside the Lenity School Road home had been deliberate and planned.
On May 19, 2025, prosecutors announced an arrest: Dorian Jeri-Greene, 39, of Monongahela, was charged with criminal homicide, robbery, burglary, and theft in the killing of Jennah Marie Seibert, 24. Investigators said video from inside the residence showed a man dressed in dark clothing and a mask entering from behind a storage shed about ten minutes after the fiancé left for work, carrying an AR-style rifle. The home’s electrical meter had been physically removed to cut power. A discharged cartridge casing, a damaged basement safe, and the theft of the victim’s car, jewelry, and narcotics were all detailed by authorities as part of the evidence trail.
Detectives reported that license-plate readers, traffic cameras, and private surveillance mapped the suspect’s movements between Westmoreland and Washington counties. After still images from a convenience store were released, tipsters identified Jeri-Greene, and police seized items in Monongahela believed stolen from the house. In early May, investigators said they found that jewelry taken from the residence had been pawned in Florida, where a later search turned up Adidas sneakers matching those seen on video and loose diamonds consistent with a necklace missing from the home. Authorities said Jeri-Greene was taken into custody in Florida on unrelated charges before being charged in this case.
As the charges were filed, the portrait of the hours around the killing of Jennah Marie Seibert, 24, grew sharper: a cut power line, a masked intruder with a rifle, a stolen vehicle traced on regional cameras, and a trail of pawned jewelry reaching out of state. Local coverage continued to track the case from the first emergency call through the identification of a person of interest to the filing of homicide and related charges, while memorial pages and funeral notices marked the loss felt in Rostraver Township and the Belle Vernon community.
