17-Year-Old High School Student Arrested in Las Vegas in Connection with Homicide of Homeless Woman
On May 5, 2026, a 17-year-old male, identified as Dennis Geiggar, was arrested in Las Vegas in connection with the April 21 death of Marceline Biasini, a 61-year-old homeless woman found with blunt head trauma on a sidewalk. The Clark County coroner ruled the death a homicide. Surveillance footage from near the scene captured audio of a scream and approximately 61 loud impact sounds, though the attack itself was not visible. Geiggar, previously expelled from Valley High School for allegedly attempting to start a fire, has a documented history of anger-related behavior and was attending school online at the time of arrest. He was reportedly seen wearing clothing matching that of a suspect in 7-Eleven surveillance. New York Post additionally reports the presence of bloody footwear impressions at the scene.
Both sources rely heavily on reporting from the Las Vegas Review-Journal and present largely identical core facts. However, New York Post provides marginally more complete coverage due to the inclusion of forensic evidence (bloody footwear impressions) and a cleaner presentation without extraneous headlines. Fox News includes distracting, unrelated crime links and uses a generic attribution ('Fox News Digital'), which may suggest a content aggregation or placeholder function.

Fox News
