Just after midnight on May 18, 2025, 25-year-old Alyssa Rose Wiest of West Conshohocken was found facedown on the 200 block of Moorehead Avenue with gunshot wounds to her torso. Investigators determined the shooting began inside her home; she fled out the front door, made it partway down the block, and collapsed. She was taken to Lankenau Hospital and pronounced dead shortly thereafter. Detectives noted the residence door was ajar, a blood trail led from inside to the sidewalk, and five projectiles were recovered inside and near her body.

Police and county detectives quickly focused on Alyssa’s boyfriend of two years, 26-year-old Michael Dutkiewicz of Warminster. A neighbor reported seeing him beside a silver Ford F-150 moments after the gunfire, and license-plate readers recorded the truck moving through the area beginning around 12:25 a.m. A warrant was issued and he turned himself in by noon the same day; he was charged with first-degree murder, third-degree murder, and possession of an instrument of crime, denied bail, and remanded pending a May 27, 2025 preliminary hearing.

Friends and colleagues described Alyssa as a young microbiologist whose promise and warmth were felt by everyone who knew her. Does anyone in West Conshohocken have information about Alyssa, the events of that night, or the silver Ford F-150 seen nearby?
