A quiet evening in the small coastal town of Westbrook, Connecticut, was shattered by violence on Wednesday, October 28, 2026. The incident left one woman, Katie Diljedahl, dead and a man critically injured from gunshot wounds. The sense of security in the community, a place of just over 7,000 residents on the Long Island Sound, was profoundly disturbed by the event, which one neighbor described as something that has "never happened around here."
The shooting brought a major police presence and a LifeStar emergency medical helicopter to a normally peaceful residential street.
Connecticut State Police from Troop F were dispatched to a home on East Pond Meadow Road at approximately 5:25 p.m. following a report of a disturbance. When troopers arrived, they encountered 37-year-old John Bongiovanni outside the residence. The scene inside the home was grim. Officers discovered two people who had been shot. Katie Diljedahl was found with gunshot wounds and was pronounced dead at the scene by emergency medical personnel.
A second victim, identified as Ryan Graham, was also found inside the home, suffering from serious gunshot wounds. He was in critical but stable condition and was airlifted by a LifeStar helicopter to Hartford Hospital for emergency medical treatment. The relationship between Bongiovanni and the two victims was not immediately disclosed by authorities, leaving the community and investigators with urgent questions about what led to the fatal encounter. The investigation continued into the next morning, with a state police mobile command center parked outside the home as detectives worked to piece together the events of that evening.
As a result of the initial investigation, troopers arrested John Bongiovanni at the scene. He was charged with murder and criminal attempt to commit murder. The following day, Thursday, October 29, Bongiovanni appeared before a judge in Middletown Superior Court. Details emerged during the hearing, where his public defender stated that Bongiovanni had "significant physical injuries" that their office intended to document. The defense attorney also noted that two weapons had been recovered from the scene.
Despite the defense's arguments for a lower amount, the judge considered the serious nature of the charges and set Bongiovanni's bond at $3 million. He was ordered to have no contact with Ryan Graham. His next court appearance was scheduled for November 10, 2026.
In the immediate aftermath, state police assured the public that there was no ongoing threat. However, the motive for the shooting remained unclear as the investigation was still in its early stages. The case left a community in shock and a family to mourn the loss of Katie Diljedahl. As of late October 2026, authorities had not released further details about the circumstances of the shooting, and the case against John Bongiovanni was pending in the Connecticut judicial system.
